-# AegisGitea-MCP
+# AegisGitea MCP
 
-Security-first MCP server for self-hosted Gitea, available as **two transports built on one shared core**:
+A full-access [Model Context Protocol](https://modelcontextprotocol.io) bridge to the whole Gitea
+API. It exposes one MCP tool per operation of the pinned Gitea 28.1.0 swagger (537 operations)
+plus `gitea_api_request` for endpoints newer than that spec: 538 tools in total. Everything is
+enabled by default, including administration, secrets, webhooks and deletes. You narrow it down
+with configuration and with the scope of the Gitea token you hand to it (see
+[ADR 0001](docs/adr/0001-full-access-by-default.md)).
 
-- **Local (stdio)** — `uvx aegis-gitea-mcp`. A single-user server for your own machine that authenticates with your Gitea Personal Access Token. No OAuth, no web stack. Ideal for Claude Desktop / Claude Code on your laptop.
-- **Server (HTTP/OAuth)** — `aegis-gitea-mcp[server]` / Docker. The public, multi-user deployment with per-user OAuth2/OIDC, dynamic client registration, rate limiting, and per-user repository authorization. Exposes MCP over Streamable HTTP and a legacy SSE alias.
+It runs over stdio (a local process started by your MCP client) and over streamable HTTP (a
+remote server). It is built on the official `mcp` Python SDK, with a hash-chained audit log, a
+bounded and secret-masked result format, and two authentication modes.
 
-Both transports share the same tools, policy engine, secret sanitization, tamper-evident audit log, and — new in 0.2.0 — **safe full-API coverage** via the policy-gated `gitea_request` escape hatch plus **resource-type-aware authorization** for the admin/user/org surface.
+Who should run it: someone who wants an AI client to operate a Gitea instance end to end, who
+owns that instance (or the token), and who accepts the trade-off below. If you only want an
+assistant to read issues, use `READ_ONLY=true` and a read-only token, or pick a different tool.
 
-> Branching / contribution flow: `HEAD -> feature branch -> dev -> main`. All pull requests target `dev`; `dev` is merged to `main` for releases. Never commit or push directly to `dev` or `main`.
+> The configured Gitea token's power is exposed to every connected client. With an admin token
+> and no filters, a connected client can delete repositories, create users, change Actions
+> secrets and rewrite webhooks. On HTTP, whoever holds `MCP_BEARER_TOKEN` has the same
+> power. Treat that token like the Gitea token, use TLS, and restrict exposure with `READ_ONLY`,
+> `TOOLSETS`, `DISABLED_TOOLS` and a narrower Gitea token when full access is not needed.
 
-## Run locally (stdio, single user)
+## Security notice: Gitea content is untrusted
 
-Install nothing and run it with [`uv`](https://docs.astral.sh/uv/):
+Issue bodies, pull request descriptions, comments, commit messages, wiki pages and file contents
+are written by other people (or by other AI agents) and can contain instructions aimed at your
+assistant. This server returns all Gitea data labelled as data: every result carries an
+`untrusted_content` notice, and the server itself never acts on instructions found in content.
+MCP clients (Claude, Mistral, local tools) must do the same: treat anything under `data` as
+data, never as instructions, and do not let it trigger further tool calls without your approval.
+Prompt injection through repository content is the main risk of giving a model write access, so
+keep tool-call confirmation on for destructive tools.

+Estimated time from a fresh clone to a working server: 5 to 10 minutes, most of it spent
+creating the token in Gitea.
+
+Prerequisites:
+
+- Python 3.10 or newer and [uv](https://docs.astral.sh/uv/)
+- A Gitea instance (the tools target 28.1.0; other versions work for the operations they share)
+- A site-admin token with every scope set to write, or the `all` scope: in Gitea open
+  Settings, Applications, Generate New Token
 
 ```bash
-GITEA_URL=https://git.hiddenden.cafe \
-GITEA_TOKEN=<your-gitea-personal-access-token> \
-uvx aegis-gitea-mcp
+git clone https://git.hiddenden.cafe/Hiddenden/AegisGitea-MCP.git
+cd AegisGitea-MCP
+uv sync
+uv run aegis-gitea-mcp setup
 ```
 
-Or install it:
+`setup` asks for the Gitea URL and the token (hidden input; or pass `--gitea-url` and set
+`GITEA_TOKEN`). It then:
+
+- checks that Gitea is reachable and reports its version;
+- checks that the token is valid, belongs to a site administrator and has the required scopes
+  (`GET /user`, `GET /token`);
+- when you give a public base URL (`--public-base-url`), registers the `aegis-gitea-mcp` OAuth
+  application in Gitea for per-user sign-in (use `--no-oauth` to skip it);
+- writes `.env` with mode 0600, generating `MCP_BEARER_TOKEN` and `TOKEN_ENCRYPTION_KEY` when
+  they are missing, and keeping values it does not know;
+- prints ready-made client configurations and a docker-compose snippet.
+
+Secrets are only ever written to the env file, never printed. `serve` reads `./.env` only
+while it keeps the 0600 mode and your ownership; to keep the file elsewhere use
+`--env-file PATH` (or `AEGIS_ENV_FILE`) on both commands.
+
+Run it:
 
 ```bash
-pip install aegis-gitea-mcp        # core only (local stdio)
-aegis-gitea-mcp                    # reads GITEA_URL + GITEA_TOKEN (or a .env file)
+# stdio: normally started by your MCP client, see "Client configuration"
+uv run aegis-gitea-mcp serve
+
+# streamable HTTP on 127.0.0.1:8080
+MCP_TRANSPORT=http uv run aegis-gitea-mcp serve
+curl http://127.0.0.1:8080/health
 ```
 
-Wire it into Claude Code:
+`/health` answers `{"status":"ok","version":...,"tools":538,"gitea":"reachable"}` when Gitea
+responds to a cached version probe, and 503 `{"status":"degraded","gitea":"unreachable"}`
+otherwise. It never includes URLs, tokens or exception text.
+
+## Token scopes
+
+Gitea tokens have scope categories: repository, issue, organization, user, admin, notification,
+package, misc and activitypub, each as read or write (write implies read), plus the special
+`all`. A token with `all` (or write on every category) enables every tool. A narrower token
+works too: calls outside its scopes fail with Gitea's own 403, which is returned in the result
+as an error with its message, so the model can see why.
+
+| Tool domain | Scope category Gitea checks (mainly) |
+|---|---|
+| repo, pull, release, wiki | repository |
+| issue (including labels and milestones) | issue |
+| org, team | organization |
+| user | user (starred, watched and own repositories fall under repository) |
+| hook | repository, organization, user or admin, depending on the hook level |
+| actions | repository, organization, user or admin, depending on the level |
+| admin | admin |
+| notification | notification |
+| package | package |
+| misc | misc |
+
+The pinned swagger has no operations under the activitypub category, so no tool needs it.
+Gitea is the authority on what a scope allows; if a call returns 403, widen the scope or the
+user's permissions.
+
+Sudo: every tool accepts an optional `sudo` argument, a Gitea login. It is sent as Gitea's
+`Sudo` header and Gitea honours it only for site-admin tokens. The acting identity and the sudo
+user are visible in every result.
+
+## Authentication modes
+
+Both modes can run on one HTTP deployment at the same time (details in
+[ADR 0004](docs/adr/0004-auth-modes.md)).
+
+- Admin-token mode (default). `GITEA_TOKEN` is used for every call. stdio always runs this way.
+  On HTTP, a request that carries the static `MCP_BEARER_TOKEN` (compared in constant time) runs
+  this way.
+- Per-user OAuth (HTTP only, `OAUTH_ENABLED=true`). Users sign in with their own Gitea account.
+  The server is an OAuth 2.1 authorization server for MCP clients with dynamic client
+  registration (what claude.ai and Mistral Le Chat expect) and a confidential OAuth client of
+  Gitea upstream (authorization code with PKCE S256 and a fixed list of granular scopes). Tool
+  calls then run with that user's own Gitea token, so Gitea enforces that user's permissions:
+  admin tools fail with Gitea's own 403 for non-admins. Upstream tokens are refreshed
+  automatically. Stored user tokens are encrypted (Fernet, key derived from
+  `TOKEN_ENCRYPTION_KEY`) in `DATA_DIR/oauth-store.json` with mode 0600; the server's own
+  tokens are stored only as SHA-256 hashes. A store written with another key stops startup until
+  the key is restored or the file is moved away. The signed-in login is visible in the
+  `identity` field of every result. Before the browser goes to Gitea, a consent page
+  (`/oauth/consent`) names the client and where the result goes and needs an explicit approval;
+  for public deployments set `OAUTH_REDIRECT_ALLOWLIST` to the hosted clients you use. An
+  OAuth-only deployment (no `MCP_BEARER_TOKEN`, no `GITEA_TOKEN`) is supported: it has no admin
+  identity to fall back to.
+
+## Client configuration
+
+The `setup` command prints these with your own values. Placeholders: `<your-gitea-token>` is the
+Gitea token, `<MCP_BEARER_TOKEN>` is the value from the env file.
+
+### Local stdio
+
+Claude Code:
 
 ```bash
-claude mcp add aegis-gitea -- uvx aegis-gitea-mcp
-# with env values:
-claude mcp add aegis-gitea -e GITEA_URL=https://git.hiddenden.cafe -e GITEA_TOKEN=<pat> -- uvx aegis-gitea-mcp
+claude mcp add --env GITEA_URL=https://git.example.com --env GITEA_TOKEN=<your-gitea-token> --transport stdio aegis-gitea -- uvx --index https://git.hiddenden.cafe/api/packages/Hiddenden/pypi/simple/ aegis-gitea-mcp
 ```
 
-Or Claude Desktop (`claude_desktop_config.json`):
+Keep `--transport stdio` and the server name after the `--env` options: `--env` accepts several
+values, so an option placed before the name would swallow it.
+
+Claude Desktop, Cursor and other local clients that read an `mcpServers` block:
 
 ```json
 {
   "mcpServers": {
     "aegis-gitea": {
       "command": "uvx",
-      "args": ["aegis-gitea-mcp"],
+      "args": ["--index", "https://git.hiddenden.cafe/api/packages/Hiddenden/pypi/simple/", "aegis-gitea-mcp"],
       "env": {
-        "GITEA_URL": "https://git.hiddenden.cafe",
-        "GITEA_TOKEN": "<your-gitea-personal-access-token>"
+        "GITEA_URL": "https://git.example.com",
+        "GITEA_TOKEN": "<your-gitea-token>"
       }
     }
   }
 }
 ```
 
-The local server resolves your PAT's Gitea user at startup and pins every call to that identity. The policy engine and `WRITE_MODE` gate still apply (writes are off by default), and the audit log is written to a per-user path (e.g. `%LOCALAPPDATA%\aegis-gitea-mcp\audit.log` on Windows, `~/.local/state/aegis-gitea-mcp/audit.log` on Linux). See [docs/local-quickstart.md](docs/local-quickstart.md).
-
-## Securing MCP with Gitea OAuth (public server)
-
-> The HTTP/OAuth server needs the web stack: install with `pip install 'aegis-gitea-mcp[server]'` (or use Docker) and run `aegis-gitea-mcp-server`.
-
-This guide uses the live deployment values as the running example:
-
-| Thing | Value |
-|-------|-------|
-| Gitea instance (`GITEA_URL`) | `https://git.hiddenden.cafe` |
-| This MCP server (`PUBLIC_BASE_URL`) | `https://gitea-mcp.hiddenden.cafe` |
-| OAuth callback to register in Gitea | `https://gitea-mcp.hiddenden.cafe/oauth/callback` |
-| MCP URL you give to Claude | `https://gitea-mcp.hiddenden.cafe/mcp` |
-
-Substitute your own hostnames if they differ. The two URLs are **different hosts**: `git.*` is Gitea, `gitea-mcp.*` is this proxy.
-
-### 1) Create a Gitea OAuth2 application
-
-1. Open `https://git.hiddenden.cafe/user/settings/applications` (or admin application settings).
-2. Create an OAuth2 app.
-3. Set the redirect URI to **this MCP server's callback** (not Gitea's own host):
-   `https://gitea-mcp.hiddenden.cafe/oauth/callback`
-   This is the only redirect URI Gitea needs — the MCP server forwards each client's real callback through a signed state parameter.
-4. Save the app and copy the generated `Client ID` and `Client Secret`.
-
-Required scopes:
-- `read:repository`
-- `write:repository` (only needed when using write tools)
-
-### 2) Configure this MCP server
+Always pass the `--index` of the project's registry. The name `aegis-gitea-mcp` is not
+registered on public PyPI, so a bare `uvx aegis-gitea-mcp` would resolve there, and whoever
+registers that name would receive your Gitea token through the environment. The owner should
+reserve the name on PyPI to close that gap (see [packaging.md](docs/packaging.md)). To run from
+a clone instead, use `uv` as the command with the arguments
+`run --directory /path/to/AegisGitea-MCP aegis-gitea-mcp serve`, or on the command line:
 
 ```bash
-cp .env.example .env
+claude mcp add --env GITEA_URL=https://git.example.com --env GITEA_TOKEN=<your-gitea-token> --transport stdio aegis-gitea -- uv run --directory /path/to/AegisGitea-MCP aegis-gitea-mcp serve
 ```
 
-Fill in exactly these values in `.env` (everything else has safe defaults):
+### Remote streamable HTTP
 
-```env
-# The Gitea instance this server talks to
-GITEA_URL=https://git.hiddenden.cafe
+The endpoint is `<base URL>/mcp` (`MCP_PATH`).
 
-# Per-user OAuth mode (recommended)
-OAUTH_MODE=true
-GITEA_OAUTH_CLIENT_ID=<client-id-from-step-1>
-GITEA_OAUTH_CLIENT_SECRET=<client-secret-from-step-1>
-
-# Public URL of THIS server (no trailing slash). Claude's MCP URL is this + /mcp
-PUBLIC_BASE_URL=https://gitea-mcp.hiddenden.cafe
-
-# Secret that signs the OAuth proxy state. Generate with: openssl rand -hex 32
-OAUTH_STATE_SECRET=<random-32-byte-minimum-secret>
-
-# Where dynamically-registered OAuth clients are stored — MUST be a writable,
-# persistent path. The default matches the aegis-mcp-data volume in compose.
-DCR_STORAGE_PATH=/var/lib/aegis-mcp/dcr_clients.json
-```
-
-### 2b) Service PAT (`GITEA_TOKEN`) — needed in practice
-
-Gitea issues **OIDC access tokens** that carry only `openid/profile/email`. They establish identity but **cannot call the repository REST API**, so in pure-OAuth mode most tools fail (you will see a generic error, or `list_repositories` returning nothing usable). Configure a service PAT so the tools actually work:
-
-1. Create a **dedicated bot account** in Gitea (not a personal account).
-2. Generate a Personal Access Token with least privilege:
-   - `read:repository`
-   - `write:repository` only if you enable `WRITE_MODE`
-3. Set it in `.env`:
-
-```env
-GITEA_TOKEN=<bot-personal-access-token>
-```
-
-This does **not** weaken per-user security. OAuth remains authoritative: before every repository call the server verifies that the signed-in user has permission on the target repo through Gitea (`_verify_user_repository_access`) and denies it otherwise. The PAT only performs the API call after that check; OAuth provides identity, per-user authorization, and audit attribution.
-
-Note: with a service PAT, `list_repositories` is **scoped to the signed-in user** — it returns only the repositories that user owns or contributes to (resolved via Gitea's repo search with the `uid` filter), not everything the bot can see. Visibility of private repos still depends on what the service token itself can access. All other tools require an explicit `owner`/`repo` and run the per-user permission check first.
-
-### 2a) Required writable volumes (read-only container)
-
-The provided `docker-compose.yml` runs the container with a **read-only root filesystem**. The server therefore needs two writable volumes, both already wired up in compose:
-
-| Path | Purpose | Volume |
-|------|---------|--------|
-| `/var/log/aegis-mcp` | tamper-evident audit log | `aegis-mcp-logs` |
-| `/var/lib/aegis-mcp` | dynamic client registration store (`DCR_STORAGE_PATH`) | `aegis-mcp-data` |
-
-If `/var/lib/aegis-mcp` is **not** writable/persistent, the OAuth `authorize`, `token`, and `register` endpoints fail and the browser shows a bare `Internal Server Error` during login. Keep the `aegis-mcp-data` volume mounted (or point `DCR_STORAGE_PATH` at another writable, persistent location), and make sure it survives restarts so registered clients are not lost.
-
-### 3) Configure Claude, Claude Code, or Cowork
-
-Claude's hosted, desktop, mobile, Claude Code, and Cowork surfaces share the same remote MCP connector infrastructure. There is no Claude-specific server code path.
-
-In claude.ai:
-
-1. Open **Settings > Connectors**.
-2. Choose **Add custom connector**.
-3. Paste `https://gitea-mcp.hiddenden.cafe/mcp`.
-4. Complete the OAuth consent flow. Dynamic Client Registration (`/register`) handles Claude client registration.
-
-In Claude Code:
+Claude Code with the static bearer token:
 
 ```bash
-claude mcp add --transport http aegis-gitea https://gitea-mcp.hiddenden.cafe/mcp
+claude mcp add --transport http aegis-gitea https://gitea-mcp.example.com/mcp --header "Authorization: Bearer <MCP_BEARER_TOKEN>"
 ```
 
-Cowork uses the same connector model and MCP URL.
+claude.ai custom connector: Settings, Connectors, Add custom connector, URL
+`https://gitea-mcp.example.com/mcp`. With OAuth enabled, leave the OAuth client fields empty.
+Claude registers itself (dynamic client registration) and sends you to Gitea to sign in.
 
-Manual OAuth client configuration remains available for clients that do not use DCR:
+Mistral Le Chat custom connector: Intelligence, Connectors, Add Connector, Custom MCP
+Connector, URL `https://gitea-mcp.example.com/mcp` (HTTPS with a valid certificate). Adding
+connectors in Le Chat may require workspace admin rights.
+Authentication is either HTTP Bearer Token with the `MCP_BEARER_TOKEN` value, or OAuth 2.1 with
+dynamic client registration so users sign in with their own Gitea account.
 
-- MCP server URL: `https://gitea-mcp.hiddenden.cafe/mcp`
-- Authentication: OAuth
-- OAuth client ID: the client id returned by `/register` or your preconfigured client id
-- OAuth client secret: only for confidential clients
+538 tools is a large tool list. Claude Code copes through tool search. For claude.ai and Le
+Chat, which may truncate or slow down on very long lists, expose a slim profile, for example:
 
-Hosted Claude callbacks are allowed by default: `https://claude.ai/api/mcp/auth_callback` and `https://claude.com/api/mcp/auth_callback`. Loopback redirects for Claude Code local development are allowed for `http://127.0.0.1:*` and `http://localhost:*`.
+```bash
+TOOLSETS=repo,issue,pull,release,wiki
+READ_ONLY=true            # drop this line when the assistant should be able to write
+```
 
-### 4) OAuth-protected MCP behavior
+## Deployment
 
-The server publishes protected-resource metadata:
+Image: `git.hiddenden.cafe/hiddenden/aegisgitea-mcp` (tag `dev` is built from the dev branch,
+`latest` from main). The compose snippet printed by `setup`:
 
-- `GET /.well-known/oauth-protected-resource`
+```yaml
+services:
+  aegis-gitea-mcp:
+    image: git.hiddenden.cafe/hiddenden/aegisgitea-mcp:dev
+    restart: unless-stopped
+    env_file: .env
+    environment:
+      MCP_TRANSPORT: http
+      MCP_HOST: 0.0.0.0  # allowed because authentication is configured
+      DATA_DIR: /var/lib/aegis-mcp
+    ports:
+      - "127.0.0.1:8080:8080"
+    volumes:
+      - aegis-mcp-data:/var/lib/aegis-mcp
+    read_only: true
+    tmpfs:
+      - /tmp
+    cap_drop:
+      - ALL
+    security_opt:
+      - no-new-privileges:true
 
-Example response:
+volumes:
+  aegis-mcp-data:
+```
+
+Put a reverse proxy with TLS in front of it. Caddy:
+
+```
+gitea-mcp.example.com {
+    reverse_proxy 127.0.0.1:8080 {
+        flush_interval -1
+    }
+}
+```
+
+For nginx, set `proxy_buffering off;` inside the proxying location so streamed responses are
+not held back. Set `PUBLIC_BASE_URL` to the public https URL and add its host to `ALLOWED_HOSTS`
+when the proxy forwards a different `Host`.
+
+Bind rules: the server binds to `127.0.0.1` by default. A non-loopback `MCP_HOST` refuses to
+start (exit code 2) unless `MCP_BEARER_TOKEN` or a complete OAuth setup is configured. Requests
+with an unexpected `Host` header are rejected (DNS-rebinding protection). The MCP endpoint is
+rate limited (`RATE_LIMIT_PER_MINUTE`) per client IP and per hash of the Authorization header.
+Behind a proxy on another address set `FORWARDED_ALLOW_IPS` so the real client IP is used. A
+non-loopback bind without `PUBLIC_BASE_URL` or `ALLOWED_HOSTS` logs a startup warning (remote
+`Host` headers get 421). The server also exits with code 2 when the audit log cannot be opened
+for append, and refuses tool calls it cannot audit.
+
+More in [docs/deployment.md](docs/deployment.md) and [docs/hardening.md](docs/hardening.md).
+
+## Configuration
+
+All settings are environment variables (or an env file), case-insensitive. The env file is
+`--env-file PATH`, else `AEGIS_ENV_FILE`, else `./.env` only when it is a regular file owned by
+you with mode 0600 (what `setup` writes); any other `./.env` is ignored with a warning (run
+`chmod 600 .env` or pass `--env-file`). Real environment variables always win. Core ones:
+
+| Variable | Default | Meaning |
+|---|---|---|
+| `GITEA_URL` | required | Gitea base URL (a trailing `/api/v1` is removed) |
+| `GITEA_TOKEN` | unset | Token for stdio and admin-token mode |
+| `MCP_TRANSPORT` | `stdio` | `stdio` or `http` |
+| `MCP_HOST`, `MCP_PORT`, `MCP_PATH` | `127.0.0.1`, `8080`, `/mcp` | HTTP bind and endpoint path |
+| `MCP_BEARER_TOKEN` | unset | Static bearer for HTTP, at least 32 characters |
+| `OAUTH_ENABLED` | `false` | Per-user OAuth on HTTP |
+| `READ_ONLY` | `false` | Expose only operations annotated read-only |
+| `TOOLSETS` | `all` | Comma separated domains to expose |
+| `DISABLED_TOOLS` | empty | Tool names to hide |
+| `SECRET_DETECTION_MODE` | `mask` | `off`, `mask` or `block` |
+
+Every variable, its default and its validation rules are in
+[docs/configuration.md](docs/configuration.md); `.env.example` is the annotated template.
+
+## What is config-gated, and what is impossible
+
+Config-gated, all optional: `READ_ONLY` (exposes only the operations annotated read-only, which
+are the GET operations plus a few POST endpoints that do not change anything, such as the
+markdown and markup render endpoints and the file-contents query; `gitea_api_request` stays
+listed but accepts only GET), `TOOLSETS` (domains), `DISABLED_TOOLS` (single tools, an unknown name is a startup
+error), and `SECRET_DETECTION_MODE` (`mask` replaces secret-like strings in results, `block`
+withholds a result that contains one, `off` disables it; exact redaction of the server's own
+tokens always applies). A filtered tool is neither listed nor callable.
+
+Not possible because Gitea's API does not offer it, so there is no tool: queue management,
+writes to the instance configuration, and instance-wide OAuth applications (UI only; setup
+registers its OAuth application as a user application of the admin). `gitea_api_request` reaches
+anything newer than the pinned spec once Gitea ships it.
+
+## Known limitations
+
+A token with the `all` scope does not make every tool work. Check
+[docs/integration-coverage.md](docs/integration-coverage.md), generated by running every tool
+against a live Gitea 28.1.0, for the per-tool outcome.
+
+- `gitea_user_create_token`, `gitea_user_get_tokens` and `gitea_user_delete_access_token` need
+  basic authentication with the account password (a Gitea API rule). The server always sends
+  token authentication, so these three return 401 through it. Create tokens in the Gitea UI.
+- Some operations depend on instance state and answer 404 or an error until it exists: the
+  commit signing keys (`gitea_misc_get_signing_key`, `gitea_repo_signing_key` and their SSH
+  variants) when the instance has none, user badges (Gitea cannot create badges through the
+  API), unadopted repositories, run artifacts, git notes and the GPG key verification, which
+  need data the instance does not have yet. The coverage report lists them with the reason.
+- Tools that depend on a runner, such as workflow runs and jobs, only return data once an
+  Actions runner is registered.
+
+## Result and error format
+
+A successful call returns one text item with JSON (see
+[ADR 0005](docs/adr/0005-result-envelope-and-errors.md)):
 
 ```json
 {
-  "resource": "https://gitea-mcp.hiddenden.cafe",

+  "data": []
 }
 ```
 
-If a tool call is missing/invalid auth, MCP endpoints return `401` with:
+`data` is the decoded JSON or text. Binary bodies become `{content_base64, content_type, size}`
+up to `MAX_BINARY_BYTES`. Output is bounded by `MAX_TOOL_RESPONSE_ITEMS` and
+`MAX_TOOL_RESPONSE_CHARS`; when something was cut, a `truncated` object says how much.
 
-```http
-WWW-Authenticate: Bearer resource_metadata="https://<mcp-host>/.well-known/oauth-protected-resource", scope="read:repository"
+Failures are results with `is_error` set and no stack trace:
+
+```json
+{
+  "error": {"status": 404, "kind": "not_found", "message": "repository does not exist"},
+  "identity": {"login": "alice", "mode": "oauth", "sudo": null},
+  "request": {"method": "GET", "path": "/repos/o/missing", "operation": "gitea_repo_get"}
+}
 ```
 
-## Architecture
+Kinds include `bad_request`, `unauthorized`, `forbidden`, `not_found`, `conflict`,
+`validation_failed`, `rate_limited`, `server_error`, `timeout`, `upstream_unreachable`,
+`redirect`, `payload_too_large`, `secret_blocked` and `invalid_argument` (the arguments did not
+match the tool schema; the message names the argument path, never its value). Messages from
+Gitea are sanitized and truncated. Calling an unknown or filtered tool is a protocol error.

-## Threat model
-
-- Shared bot tokens are dangerous:
-  - one leaked token can expose all repositories reachable by that bot account.
-  - blast radius is repository-wide and cross-user.
-- Token-in-URL is insecure:
-  - URLs leak via logs, proxies, browser history, and referers.
-  - bearer tokens must be sent in `Authorization` headers only.
-- Per-user OAuth reduces lateral access:
-  - identity comes from Gitea OIDC/JWKS or userinfo validation.
-  - without `GITEA_TOKEN`, API calls use the user's token and Gitea enforces permissions.
-  - with `GITEA_TOKEN`, every repository-targeted call first checks the user's Gitea permission and fails closed if the check cannot be made.
-
-## CI/CD
-
-Gitea workflows were added under `.gitea/workflows/`:
-
-- `lint.yml`: Ruff + formatting + mypy.
-- `test.yml`: lint + pytest + enforced coverage (`>=80%`).
-- `docker.yml`: lint+test gated Docker build, SHA tag, `latest` tag on `main`.
-- `publish.yml`: on a `v*` tag, lint+test gated `uv build` + publish the Python package to the Gitea PyPI registry (see `docs/packaging.md`).
-
-## Docker hardening
-
-`docker/Dockerfile` uses a multi-stage build, non-root runtime user, production env flags, minimal runtime dependencies, and a healthcheck.

 The server holds per-user Gitea tokens. That is the most sensitive asset after

+
+## Implementation notes (chunk B5)
+
+- **OAuth-only deployments are allowed.** With `OAUTH_ENABLED=true`, no
+  `MCP_BEARER_TOKEN` and no `GITEA_TOKEN`, the server starts and every user
+  brings their own Gitea token. Admin-token mode is then unavailable and fails
+  closed. `GITEA_TOKEN` stays required whenever admin-token mode is reachable
+  (a static bearer, or an unauthenticated loopback endpoint).
+- **Own consent step.** Gitea remembers consent for our single Gitea
+  application, so a dynamically registered client with an attacker's redirect
+  URI could otherwise obtain a token for a victim who merely opens a link (the
+  confused-deputy problem of OAuth proxies). `/authorize` therefore leads to our
+  consent page, which names the client and the redirect URI. Approving needs a
+  CSRF token bound by a `SameSite=Strict` cookie and a matching `Origin`, and
+  sets a browser-binding cookie that `/oauth/callback` requires, so a Gitea
+  redirect URL obtained by someone else cannot be completed in another browser.
+- **Token binding.** Tokens are bound to the MCP endpoint URL (RFC 8707) and
+  carry the single scope `gitea`; the SDK enforces both
+  (`validate_token_resource=True`, `required_scopes=["gitea"]`), and the static
+  bearer reports the same resource and scope. `/authorize` with another
+  `resource` is refused with `invalid_target`.
+- **Replay handling.** A replayed authorization code, or a rotated-out refresh
+  token presented again, revokes the whole grant (RFC 6749 4.1.2, OAuth 2.1
+  refresh token reuse detection). Revoking either token ends the grant.
+- **Store key.** The Fernet key is HKDF-SHA256(`TOKEN_ENCRYPTION_KEY`,
+  info `aegis-gitea-mcp oauth store`), so the setting can be any long random
+  string. Changing it makes the store unreadable; startup then stops instead of
+  wiping the file.
+- **Limits.** At most 500 registered clients (the least recently used client
+  without a session is evicted, otherwise registration is refused), 50
+  sessions per Gitea login (the oldest ends), and 1024 pending sign-ins. The
+  unauthenticated OAuth endpoints share the per-IP rate limit, and query
+  strings are removed from access log lines.

+## Amendments
+
+### Secret handling in results (implemented in `gitea/executor.py`, `gitea/encoding.py`)
+
+Two layers run on every result, success and error, before the size limit:
+
+1. Exact redaction (always on, independent of `SECRET_DETECTION_MODE`). The
+   following values are replaced with `[REDACTED]` wherever they occur in a
+   string or dict key of the payload: the token of the calling identity,
+   `GITEA_TOKEN`, `MCP_BEARER_TOKEN`, `GITEA_OAUTH_CLIENT_SECRET`, the
+   `extra_secrets` given to the executor, and secret values submitted in the
+   request body of the same call.
+2. Pattern masking (`SECRET_DETECTION_MODE`). `off` skips it. `mask` replaces
+   each match of the secret patterns (provider keys, JWTs, private key headers,
+   generic `api_key`/`token` assignments) with a shortened form. `block`
+   withholds the whole result and returns an `is_error` result of kind
+   `secret_blocked`.
+
+Request-body secret fields. Values of these fields, when at least 4 characters
+long, are collected from the submitted body (nested objects and lists up to a
+depth of 8) and redacted from the result of that call, because Gitea echoes
+some of them back (a created webhook returns its `authorization_header`):
+`password`, `secret`, `client_secret`, `token`, `access_token`, `auth_password`,
+`auth_token`, `private_key`, `authorization_header`, `remote_password`,
+`mirror_password`, `mirror_token`, `aws_secret_access_key`, `aws_access_key_id`.
+For Action secret writes the `data` value is redacted at any length. Only the
+value sent in the same call is known to the executor, so a later read of an
+object that stores such a value is not covered by this rule (pattern masking
+still applies).
+
+Credential-issuing operations. The successful results of
+`CREDENTIAL_ISSUING_OPERATIONS` skip pattern masking and block mode, because
+their whole purpose is to hand the caller a freshly minted credential that
+masking would make unusable (and block mode would refuse to deliver):
+
+- `userCreateToken` (access token)
+- `adminCreateRunnerRegistrationToken`, `orgCreateRunnerRegistrationToken`,
+  `repoCreateRunnerRegistrationToken`, `userCreateRunnerRegistrationToken`
+  (Actions runner registration tokens, delivered in a response header)
+- `userCreateOAuth2Application`, `userUpdateOAuth2Application` (OAuth2
+  `client_secret`)
+- `repoCreateDeployToken` (deploy token)
+
+Exact redaction still applies to these results, so the caller's own tokens are
+never echoed, and their errors are masked like every other error. Operators who
+do not want any credential to pass through the model context should disable
+these tools with `DISABLED_TOOLS`.
+
+Hardening of the result path: JSON from Gitea nested deeper than 100 levels is
+returned as text instead of being parsed (the recursive redaction and masking
+passes must not hit the interpreter recursion limit), and a base64 file upload
+whose decoded size would exceed `MAX_BINARY_BYTES` is rejected before it is
+decoded with kind `payload_too_large`.
+
+### Path encoding and the raw tool
+
+Path values are percent-encoded with `/` escaped as `%2F`, except for the
+parameters that Gitea 28.1.0 serves through wildcard routes (branch, tag, file
+path, ref and compare names on `branches`, `tags`, `contents`, `contents-ext`,
+`raw`, `media`, `compare`, `git/refs`, `commits/{ref}/status(es)` and
+`pulls/{base}/{head}`). The decision is keyed on the route and the parameter,
+not the parameter name: `releases/tags/{tag}` and `editorconfig/{filepath}` are
+single-segment routes that only resolve with `%2F`.
+
+The raw tool `gitea_api_request` rejects `%` in paths, so it cannot send
+`%2F`. A route with a single-segment parameter whose value contains a slash
+(a release tag such as `rel/1.0`) must be called through the generated tool for
+that operation.

-
-- `gitea_request` (`method`, `path`, optional `query`, `body`)

-    writes and require write-mode plus a whitelisted repository. Admin/credential
-    endpoints are blocked unless `RAW_API_ALLOW_SENSITIVE=true`. See
-    [Raw API Dispatch](raw-api.md) for the two-layer policy model and full details.
-
-Note: `create_issue`, `add_labels`, and `remove_labels` accept label **names**; the
-server resolves them to Gitea label ids and returns a clear error for unknown labels.
-
-Note: the `milestone` argument on `create_issue`/`update_issue` accepts either a numeric
-milestone **id** or a milestone **title** (resolved case-insensitively against open and
-closed milestones; unknown titles return a clear error). On `update_issue`, `milestone: 0`
-clears the issue's milestone. Gitea Projects (Kanban boards) are intentionally unsupported:
-the Gitea REST API exposes no project endpoints.

 # Architecture
 
+AegisGitea MCP turns the Gitea REST API into MCP tools. The design decisions are recorded in
+[docs/adr](adr/0001-full-access-by-default.md); this page describes how the pieces fit.
+
 ## Overview
 
-AegisGitea MCP is a Python 3.10+ application split into a **transport-agnostic core** and **two thin transport adapters** that consume it. It bridges an AI client (Claude, Claude Code, Cowork) and a self-hosted Gitea instance, implementing the [Model Context Protocol (MCP)](https://modelcontextprotocol.io).

-Where the security layers sit on a dispatched call: **scope check → policy
-(`policy.py`) → resource-type authorization (`authz.py`) → handler → response
-limits + secret sanitization → audit**. For `gitea_request`, the handler adds a
-deterministic write classifier, a known-path gate, and the admin/credential
-denylist. The HTTP adapter runs the per-user repository-permission probe and the
-resource-type gate; the stdio adapter trusts the PAT owner and skips the
-per-user probe while keeping policy, `WRITE_MODE`, and audit.
+Every tool call is audited (a write-ahead `tool_call_started` entry, then one `tool_invocation` entry with the outcome), and every result is wrapped in the same envelope.

+`server.py` builds a low-level `mcp` SDK `Server` (ADR 0002) because the high-level server cannot
+register tools from raw JSON schemas.
 
-- Defines all HTTP routes
-- Reads configuration on startup and initialises `GiteaClient`
-- Applies authentication middleware to protected routes
-- Dispatches tool calls to the appropriate handler function
-- Handles CORS
+- `list_tools` returns one tool per catalog operation, plus the hand-written
+  `gitea_api_request` ([raw-api.md](raw-api.md)). The filters `TOOLSETS`, `READ_ONLY` and
+  `DISABLED_TOOLS` apply here and again when a tool is called, so a filtered tool is unknown.
+  Unknown names in `DISABLED_TOOLS` are a startup error.
+- `call_tool` validates the arguments with `jsonschema` (the SDK does not), resolves the
+  identity, runs the executor, writes the audit event and returns the result. Failures of the
+  tool are `is_error` results the model can read; only protocol problems (an unknown tool) are
+  protocol errors. Validation messages never contain the offending value, so a secret typed into
+  the wrong field is not echoed.
+- Unexpected exceptions are caught, audited as internal errors and returned as a generic
+  message. A stack trace never leaves the process.
 
-### `auth.py`
+## Executor
 
-API key validation. Responsibilities:
+`GiteaExecutor.execute(operation, arguments, identity)` builds one HTTP request:
 
-- `APIKeyValidator` class: holds the set of valid keys, tracks failed attempts per IP
-- Constant-time comparison to prevent timing side-channels
-- Rate limiting: blocks IPs that exceed `MAX_AUTH_FAILURES` within `AUTH_FAILURE_WINDOW`
-- Helper functions for key generation and hashing
-- Singleton pattern (`get_validator()`) with test-friendly reset (`reset_validator()`)
+- path parameters are validated and percent-encoded; query and JSON or multipart bodies are
+  built from the schema; the `sudo` value becomes the `Sudo` header;
+- the request carries the identity's Gitea token. Redirects are never followed and cookies are
+  never kept, so one identity cannot leak into another call;
+- responses: JSON and text are decoded, binary bodies become base64 up to `MAX_BINARY_BYTES`,
+  `Link` and `X-Total-Count` become pagination metadata;
+- errors: Gitea's message is extracted, sanitized and truncated, then mapped to a stable `kind`;
+- output: items and characters are bounded, the identity's tokens, the configured secrets and
+  secret values submitted in the request are redacted by exact match, and
+  `SECRET_DETECTION_MODE` masks or blocks secret-like strings;
+- the envelope (ADR 0005) carries the identity, the request, the status, pagination and the
+  `untrusted_content` notice.
 
-### `config.py`
+The executor never raises for upstream or argument problems; each is a result with `is_error`.
 
-Pydantic `BaseSettings` model. Responsibilities:
+## Transports
 
-- Loads all configuration from environment variables or `.env`
-- Validates values (log level enum, token format, key minimum length)
-- Parses comma-separated `MCP_API_KEYS` into a list
-- Exposes computed properties (e.g. base URL for Gitea API)
+stdio (`MCP_TRANSPORT=stdio`, the default) serves one client over stdin and stdout. stdout is
+reserved for JSON-RPC, all logging goes to stderr. It always runs as admin-token mode with
+`GITEA_TOKEN`.
 
-### `gitea_client.py`
+streamable HTTP (`MCP_TRANSPORT=http`) is the SDK's Starlette app served by uvicorn at
+`MCP_PATH`, stateless, wrapped with:
 
-Async HTTP client for the Gitea API. Responsibilities:
+- bearer authentication and, with OAuth on, the OAuth endpoints of the SDK;
+- DNS-rebinding protection (allowed `Host` values: loopback with the port, the host of
+  `PUBLIC_BASE_URL`, `ALLOWED_HOSTS`);
+- rate limiting per client on the MCP path;
+- `GET /health` and `GET /` (name, version, MCP path).
 
-- Wraps `httpx.AsyncClient` with bearer token authentication
-- Maps HTTP status codes to typed exceptions (`GiteaAuthenticationError`, `GiteaNotFoundError`, etc.)
-- Enforces file size limit before returning file contents
-- Logs all API calls to the audit logger
+Startup is fail-closed: a non-loopback bind without authentication, or OAuth enabled with
+missing settings, exits with code 2 before listening.
 
-Key methods:
+## Authentication and identity
 
-| Method | Gitea endpoint |
+ADR 0004 has the full decision. Two modes can run together on HTTP.
+
+Admin-token mode: the static `MCP_BEARER_TOKEN` is compared in constant time (digests are
+compared, so length does not leak). A match runs the call as `GITEA_TOKEN`, with the admin login
+resolved once from `GET /user`. stdio is always this mode.
+
+Per-user OAuth mode: the server is an OAuth 2.1 authorization server for MCP clients (dynamic
+client registration, PKCE) and a confidential OAuth client of Gitea. `/authorize` parks the
+request and shows the consent page `/oauth/consent` (client name, redirect URI, approval with
+CSRF and origin checks) before the browser goes to Gitea. `/oauth/callback` receives Gitea's
+code in the same browser, exchanges it, and issues the client opaque access and refresh tokens
+that map to the user's Gitea tokens. A call with such a token runs with the user's own Gitea access token,
+so Gitea enforces that user's permissions. The mapping lives in `DATA_DIR/oauth-store.json`
+(mode 0600). Gitea tokens in it are encrypted with Fernet (key derived from
+`TOKEN_ENCRYPTION_KEY`); our own tokens are stored as SHA-256 hashes. Upstream refresh is
+automatic.
+
+One token verifier accepts either kind. The dispatcher turns the verified token into an
+`Identity` (login, mode, token). The token is kept out of `repr` and out of every result and log.
+
+## Audit
+
+Every tool call, including failed and invalid ones, produces exactly one result event in the
+append-only, hash-chained audit log, after a write-ahead event that makes a call fail closed when
+the log stops accepting writes. Only argument names are recorded, never values. Details and
+integrity validation are in [audit-logging.md](audit-logging.md).
+
+## Request flow
+
+1. The client sends `tools/call` (stdio, or HTTP with a bearer token).
+2. HTTP only: host check, rate limit, token verification (static bearer or OAuth).
+3. The dispatcher looks the tool up (filters applied), validates the arguments against the
+   schema, and resolves the identity.
+4. The executor calls Gitea with the identity's token.
+5. The response is bounded, redacted and masked, and wrapped in the envelope.
+6. One audit result event is written and the result is returned. (A write-ahead
+   `tool_call_started` event is written right after the tool lookup in step 3; when it cannot be
+   written the call is refused.)

-### `audit.py`
-
-Structured audit logging using `structlog`. Responsibilities:
-
-- Initialises a `structlog` logger writing JSON to the configured log file
-- `log_tool_invocation()`: records tool calls with result and correlation ID

-
-MCP data models and tool registry. Responsibilities:
-
-- Pydantic models: `MCPTool`, `MCPToolCallRequest`, `MCPToolCallResponse`, `MCPListToolsResponse`
-- `AVAILABLE_TOOLS` list: the canonical list of tools exposed to clients
-- `get_tool_by_name()`: lookup helper used by the dispatcher
-
-### `tools/repository.py`
-
-Concrete tool handler functions. Responsibilities:
-
-- `list_repositories_tool()`: calls `GiteaClient.list_repositories()`, formats the result
-- `get_repository_info_tool()`: calls `GiteaClient.get_repository()`, formats metadata
-- `get_file_tree_tool()`: calls `GiteaClient.get_tree()`, flattens to a list of paths
-- `get_file_contents_tool()`: calls `GiteaClient.get_file_contents()`, decodes base64
-
-All handlers return a plain string. `server.py` wraps this in an `MCPToolCallResponse`.

-
-## Key Design Decisions
-
-**Read by default, writes opt-in.** Read tools are available by default. Write-capable tools require `WRITE_MODE=true`, repository write policy/whitelist approval, and `write:repository` authorization.
-
-**Gitea controls repository access.** Without `GITEA_TOKEN`, Gitea enforces repository permissions on API calls made with the user's token. With `GITEA_TOKEN`, the service PAT can only execute after the server verifies the requesting user's actual repository permission through Gitea and writes an audit denial if the check fails.
-
-**Public tool discovery.** `GET /mcp/tools` requires no authentication so that MCP clients can discover the available tools without credentials. All other endpoints require authentication.
-
-**Minimal persisted state.** The audit log is persisted for tamper-evident review. Dynamic OAuth client registrations are persisted when DCR is enabled. Rate limit counters and short-lived authz caches are in-memory and reset on restart.
-
-**Async throughout.** FastAPI + `httpx.AsyncClient` means all Gitea API calls are non-blocking, allowing the server to handle concurrent requests efficiently.

-# Audit Logging
+# Audit logging
 
-## Design
+Every tool call produces exactly one result event (`tool_invocation`) in an append-only,
+hash-chained JSON-lines log, whether it succeeded, failed at Gitea, failed validation or hit an
+internal error. A call to a known tool is preceded by a small write-ahead event
+(`tool_call_started`, see Location and permissions). Security events are logged in the same
+chain.
 
-Audit logs are append-only JSON lines with hash chaining:
-- `prev_hash`: previous entry hash.
-- `entry_hash`: hash of current entry payload + previous hash.
+## What an event contains
 
-This makes tampering detectable.
+Each line is one JSON object:
 
-## Event Types
+| Field | Meaning |
+|---|---|
+| `timestamp` | UTC, ISO 8601 |
+| `event_type` | `tool_invocation`, `tool_call_started`, `access_denied` or `security_event` |
+| `request_id` | Correlation id of the request |
+| `payload` | The event data, see below |
+| `prev_hash` | `entry_hash` of the previous line (`GENESIS` for the first) |
+| `entry_hash` | SHA-256 over the previous hash and this entry |
 
-- `tool_invocation`
-- `access_denied`
-- `security_event`
+A tool invocation payload records:
 
-Each event includes timestamps and correlation context.
+- the tool name, its domain, the HTTP method and the path template (for example
+  `/repos/{owner}/{repo}/issues`, never the filled-in values);
+- the identity: Gitea login and mode (`admin-token` or `oauth`), and the sudo user when one was
+  given;
+- the HTTP status when Gitea answered, and the outcome: success, or the error kind
+  (`not_found`, `forbidden`, `invalid_argument`, `internal_error`, ...);
+- the duration in milliseconds and the correlation id;
+- who called: the MCP client id of the verified token (`aegis-static-bearer` for the static
+  bearer), a 12 character hash of the OAuth grant's session id (`session`, only for OAuth
+  tokens, never the id or a token) and the source address (`client_ip`, HTTP only; behind a
+  proxy it is the forwarded address only when the proxy is in `FORWARDED_ALLOW_IPS`);
+- the argument names, sorted, and only names that are properties of the tool's schema; any other
+  name is counted in `rejected_argument_count`. Argument values are never logged, so request
+  bodies, secret values and file contents do not reach the log. A call to a tool that does not
+  exist is recorded as `(unknown tool, N chars)`: the caller's string is neither logged nor
+  echoed in the error.
 
-## Integrity Validation
+All payloads also pass through secret masking before they are written
+(`SECRET_DETECTION_MODE` other than `off`).
 
-Use:
+## Integrity
+
+Each entry hashes the previous one, so editing, deleting or reordering a line breaks the chain
+from that point on. Validate it with:
 
 ```bash
-python3 scripts/validate_audit_log.py --path /var/log/aegis-mcp/audit.log
+make validate-audit                                   # default path
+uv run python scripts/validate_audit_log.py --path /var/lib/aegis-mcp/audit.log
 ```
 
-Exit code `0` indicates valid chain, non-zero indicates tamper/corruption.
+Exit code 0 means the chain is intact; 1 lists the lines that do not verify. The default path is
+`AUDIT_LOG_PATH`, else `DATA_DIR/audit.log`.
 
-## Operational Expectations
+The chain proves that history was not altered after the fact. It does not stop someone with
+write access to the whole file from rewriting it consistently from the start, so also ship the
+log to storage the server cannot modify, and compare the latest `entry_hash` against a copy you
+keep elsewhere.
 
-- Persist audit logs to durable storage.
-- Protect write permissions (service account only).
-- Validate integrity during incident response and release checks.
+## Location and permissions
+
+The log is written to `AUDIT_LOG_PATH`, default `DATA_DIR/audit.log` (`/var/lib/aegis-mcp` in the
+image). Keep it on durable storage, readable and writable only by the service account.
+The server creates a missing state directory with mode 0700 and the log with mode 0600, tightens
+an older log it owns that is group or world readable, and refuses to open the log through a
+symlink (startup exits with code 2). A keyed (HMAC) chain is not offered: the chain is
+tamper-evident only, so ship the log off the host as the integrity control.
+
+The server opens the file for append at startup and exits with code 2 (message on stderr) when
+that fails, so it never runs unaudited. The check does not stop at startup: each call to a known
+tool first writes a `tool_call_started` entry (tool name, domain and correlation id), and when
+that write fails (full disk, revoked mount, closed file) the call is refused with
+`audit_unavailable` and never reaches Gitea. Calls resume as soon as writes work again. A write
+failure of the final `tool_invocation` entry after a call has executed is only logged to stderr:
+the Gitea side effect already happened and the caller must still receive the result. The
+`correlation_id` of both entries is the request id, which is also the entry's `request_id`.
 
 ## Rotation
 
-The server appends to a single audit file and does not rotate it in process — rotating
-mid-stream would break the `prev_hash`/`entry_hash` chain. Manage growth externally with

 # Configuration
 
-Copy `.env.example` to `.env` and set values before starting:
+All settings are environment variables. They are read case-insensitively from the process
+environment and from an env file (the environment always wins). Unknown variables are ignored.
+A blank value (`KEY=` in the env file) counts as unset for the optional secrets, URLs and
+paths. List values accept commas or whitespace as separators.
+
+## Which env file is read
+
+The env file is never trusted just because it sits in the working directory: MCP clients start
+stdio servers inside the project they work on, which can be a cloned repository carrying a
+planted `.env` that switches off secret masking or the audit log or points `GITEA_URL` at
+another host. The file is chosen in this order:
+
+1. `--env-file PATH` of `serve` (and `setup`): used as given. It must exist and be a regular
+   file.
+2. The `AEGIS_ENV_FILE` environment variable: same rules.
+3. `./.env`, but only when it is a regular file (not a symlink), owned by the user running the
+   server, with no group or other permissions (mode 0600, which `setup` writes). Otherwise it is
+   ignored and one warning goes to stderr that says why and how to fix it:
+   `chmod 600 .env`, or pass `--env-file`.
+
+Real environment variables take precedence over every file. A missing `./.env` is silent.
+Containers pass settings as environment variables (`env_file:` in compose), not through the
+working directory.
+
+`.env.example` is the annotated template. `uv run aegis-gitea-mcp setup` fills one in for you
+(see [getting-started.md](getting-started.md)). Secret settings never appear in logs, errors or
+`repr` output.
+
+Requirements that depend on how the server is started are checked at start, not on import:
+`GITEA_TOKEN` for stdio, authentication for a non-loopback HTTP bind, complete OAuth settings
+when OAuth is on.
+
+## Gitea
+
+| Variable | Default | Rules |
+|---|---|---|
+| `GITEA_URL` | required | `http` or `https`, must have a host, no credentials, query or fragment, and no whitespace, backslash or control characters. A trailing `/api/v1` is removed and the URL is rebuilt from its parsed parts. Plain `http` to a host that is not loopback starts, but `serve` prints a warning on stderr because every token then travels unencrypted. |
+| `GITEA_TOKEN` | unset | Token for stdio and for admin-token mode on HTTP. Its scopes bound what the server can do. Required for stdio (exit code 2 without it). |
+
+## Transport
+
+| Variable | Default | Rules |
+|---|---|---|
+| `MCP_TRANSPORT` | `stdio` | `stdio` or `http`. `serve --transport` overrides it. |
+| `MCP_HOST` | `127.0.0.1` | Bind address for HTTP. A non-loopback value refuses to start unless HTTP auth is configured. |
+| `MCP_PORT` | `8080` | 1 to 65535. |
+| `MCP_PATH` | `/mcp` | Starts with a single `/`, no query, spaces or trailing slash, not just `/`. |
+| `MCP_BEARER_TOKEN` | unset | Static bearer token for HTTP (admin identity). At least 32 characters. Generate with `openssl rand -hex 32`. |
+| `PUBLIC_BASE_URL` | unset | Public URL behind a reverse proxy. Same URL rules as `GITEA_URL`, and `https` unless the host is loopback. Required for OAuth. |
+| `ALLOWED_HOSTS` | empty | Extra `Host` header values accepted behind a proxy. The loopback names with the port and the host of `PUBLIC_BASE_URL` are always allowed. Other `Host` values are rejected (DNS-rebinding protection). A non-loopback `MCP_HOST` with neither `PUBLIC_BASE_URL` nor `ALLOWED_HOSTS` logs a startup warning on stderr, because remote clients then get 421. |
+| `FORWARDED_ALLOW_IPS` | `127.0.0.1` | Comma list of IP addresses or networks (or `*`) whose `X-Forwarded-For` and `X-Forwarded-Proto` headers are trusted. Set it to the address of the reverse proxy when it is not on the same host, for example a Docker network. Otherwise the per-IP rate limit sees the proxy address for every client: a request that carries `X-Forwarded-For` from a peer outside this list is not honoured and logs one warning ("add its address to FORWARDED_ALLOW_IPS"). `*` trusts every peer and logs a warning: only use it when the port is reachable solely from the proxy, since clients could otherwise spoof their IP. |
+
+## Per-user OAuth (HTTP only)
+
+| Variable | Default | Rules |
+|---|---|---|
+| `OAUTH_ENABLED` | `false` | When true, `GITEA_OAUTH_CLIENT_ID`, `GITEA_OAUTH_CLIENT_SECRET`, `TOKEN_ENCRYPTION_KEY` and `PUBLIC_BASE_URL` are required, or the server refuses to start (exit code 2, with the list of what is missing). |
+| `GITEA_OAUTH_CLIENT_ID` | unset | Client id of the Gitea OAuth application (created by `setup`). |
+| `GITEA_OAUTH_CLIENT_SECRET` | unset | Its client secret. |
+| `TOKEN_ENCRYPTION_KEY` | unset | At least 32 characters. Encrypts the token store. The key cannot be rotated in place: a store written with another key stops startup (exit code 2) instead of being wiped, until you restore the original key or move `DATA_DIR/oauth-store.json` away, which signs every user out. |
+| `OAUTH_SCOPES` | all `write:<category>` scopes | Granular Gitea scopes only (`read:` or `write:` plus activitypub, admin, issue, misc, notification, organization, package, repository, user). Anything else is rejected, because Gitea grants full access for unknown scope strings. Must not be empty. |
+| `OAUTH_REDIRECT_ALLOWLIST` | empty | Comma list of redirect URIs MCP clients may register: exact URIs (`https://client.example/cb`) or prefixes ending in `/` that allow a whole host (`https://claude.ai/`). A bare origin without a path is refused. Empty accepts any https URI (and http on `localhost`, `127.0.0.1`, `[::1]`). With a list, https URIs must match it; loopback URIs stay allowed for native clients. Checked at registration and again at `/authorize`. |
+
+`PUBLIC_BASE_URL` is also required for OAuth. The Gitea OAuth application's redirect URI is
+`<PUBLIC_BASE_URL>/oauth/callback`.
+
+OAuth-only deployments are supported: with `OAUTH_ENABLED=true` and neither `MCP_BEARER_TOKEN`
+nor `GITEA_TOKEN`, every user brings their own Gitea token and admin-token mode is simply not
+available (nothing falls back to it). `GITEA_TOKEN` stays required whenever admin-token mode is
+reachable: with a static bearer, without any HTTP authentication, and on stdio.
+
+Sign-in flow and limits: `/authorize` sends the browser to the consent page `/oauth/consent`,
+which names the client and the redirect URI and needs an explicit approval (CSRF token, cookie
+and an `Origin` that matches `PUBLIC_BASE_URL`) before the browser goes to Gitea; the callback
+`/oauth/callback` completes only in that same browser. Issued `agm_` access tokens live 1 hour
+and refresh tokens 30 days (rotated on use, reuse revokes the grant); authorization codes live 5
+minutes and pending sign-ins 10 minutes. Bounds: 500 registered clients (10 redirect URIs and 8
+KiB of metadata each), 1024 pending sign-ins and codes, 50 sessions per Gitea login, and per
+client address 20 pending sign-ins and 20 registrations per hour. The consent form body is
+limited to 16 KiB and must be `application/x-www-form-urlencoded`.
+
+## State
+
+| Variable | Default | Rules |
+|---|---|---|
+| `DATA_DIR` | `~/.local/state/aegis-gitea-mcp` (`/var/lib/aegis-mcp` in the image) | `~` is expanded. Holds the encrypted token store (`oauth-store.json`, mode 0600) and the audit log. A new directory is created with mode 0700; an existing one must belong to the running user and is tightened to 0700, otherwise OAuth startup fails. |
+| `AUDIT_LOG_PATH` | `DATA_DIR/audit.log` | Path of the hash-chained audit log. See [audit-logging.md](audit-logging.md). The server opens it for append at startup and exits with code 2 and a message on stderr when it cannot. |
+
+## Tool exposure
+
+Everything is enabled by default. These settings only narrow it. A filtered tool is neither
+listed nor callable.
+
+| Variable | Default | Rules |
+|---|---|---|
+| `READ_ONLY` | `false` | Expose only operations annotated read-only (GET plus a few non-mutating POST endpoints such as the render endpoints). `gitea_api_request` stays listed but accepts only GET. |
+| `TOOLSETS` | `all` | Comma separated domains: `admin`, `repo`, `issue`, `pull`, `release`, `wiki`, `org`, `team`, `user`, `actions`, `hook`, `package`, `notification`, `misc`, or `all`. Unknown domains are rejected. `gitea_api_request` belongs to `misc`. |
+| `DISABLED_TOOLS` | empty | Exact tool names to hide, lowercased on load. An unknown name is a startup error that lists the bad names. |
+
+## Limits and safety
+
+| Variable | Default | Rules |
+|---|---|---|
+| `REQUEST_TIMEOUT_SECONDS` | `30` | 1 to 600. Timeout of each Gitea request. |
+| `MAX_TOOL_RESPONSE_ITEMS` | `200` | At least 1. Longer lists are cut and reported in `truncated`. |
+| `MAX_TOOL_RESPONSE_CHARS` | `60000` | At least 1. Upper bound of one serialized result. |
+| `MAX_BINARY_BYTES` | `5242880` | At least 1. Larger binary bodies fail with `payload_too_large`. |
+| `SECRET_DETECTION_MODE` | `mask` | `off`, `mask` or `block`. See below. |
+| `LOG_LEVEL` | `INFO` | `DEBUG`, `INFO`, `WARNING`, `ERROR` or `CRITICAL`. Logs go to stderr. |
+| `EXPOSE_ERROR_DETAILS` | `false` | When true, the exception class name is added to internal and transport errors. Never a stack trace. Do not enable in production. |
+| `RATE_LIMIT_PER_MINUTE` | `120` | At least 1. Per client on the HTTP MCP endpoint and on the unauthenticated OAuth endpoints (`/register`, `/authorize`, `/token`, `/revoke`, `/oauth/consent`, `/oauth/callback`), keyed by the client IP (an IPv6 client counts per /64) and, on the MCP endpoint, by a hash of the Authorization header. Excess requests get 429. Only the first rejected request per client and minute is written to the audit log. Tracking is in memory and bounded (idle clients are forgotten). |
+
+Secret detection: `mask` replaces secret-like strings in results with a placeholder, `block`
+withholds a whole result that contains one (`secret_blocked`), `off` disables pattern matching.
+The server's own tokens (Gitea token, bearer token, OAuth client secret, the calling user's
+token) and secret values you submit in a request body are always redacted by exact match. The
+tools that exist to return a new credential (create token, runner registration token, OAuth
+application, deploy token) are exempt from pattern masking so the credential stays usable.

 # Deployment
 
-## Secure Defaults
+This page covers running the HTTP server for remote clients. For a local stdio setup see
+[getting-started.md](getting-started.md). Read [hardening.md](hardening.md) as well: this server
+hands the power of its Gitea token to every client that can authenticate.
 
-- Default bind is `127.0.0.1`.
-- Binding `0.0.0.0` requires `ALLOW_INSECURE_BIND=true`.
-- Write mode disabled by default.
-- Policy checks run before tool execution.
-- OAuth-protected MCP challenge responses are enabled by default for tool calls.
+## Choose a mode
 
-## Local stdio install (single user)
-
-The local transport needs only the core package (no web stack):
-
-```bash
-pip install aegis-gitea-mcp            # or: uvx aegis-gitea-mcp
-GITEA_URL=https://git.hiddenden.cafe GITEA_TOKEN=<pat> aegis-gitea-mcp
-```
-
-It authenticates with your Gitea PAT, runs policy + `WRITE_MODE` + audit, and
-serves over stdio for Claude Desktop / Claude Code. See
-[local-quickstart.md](local-quickstart.md).
-
-## Local Development (HTTP server)
-
-```bash
-make install-dev
-cp .env.example .env
-make run
-```
-
-The HTTP server requires the web stack. From a published package that is the
-`[server]` extra:
-
-```bash
-pip install 'aegis-gitea-mcp[server]'
-aegis-gitea-mcp-server
-```
+- Admin-token only: set `GITEA_TOKEN` and `MCP_BEARER_TOKEN`. Every client with the bearer token
+  acts as the token owner.
+- Per-user OAuth: additionally set `OAUTH_ENABLED=true` with the OAuth settings. Users sign in
+  with their own Gitea account (after a consent step on `/oauth/consent`) and act under their
+  own permissions. The static bearer keeps working next to it as the admin identity; leave
+  `MCP_BEARER_TOKEN` unset to turn that off.
+- OAuth only: `OAUTH_ENABLED=true` with neither `MCP_BEARER_TOKEN` nor `GITEA_TOKEN`. The server
+  starts and serves signed-in users only; admin-token mode does not exist in this deployment, so
+  no request can ever fall back to an admin identity. Recommended for public deployments.
 
 ## Docker
 
-Use `docker/Dockerfile`:
+Image: `git.hiddenden.cafe/hiddenden/aegisgitea-mcp`. Tag `dev` is built from the dev branch and
+`latest` from main. `uv run aegis-gitea-mcp setup` prints this compose service, with your port:
 
-- Multi-stage image build.
-- Non-root runtime user.
-- Production env flags (`NODE_ENV=production`, `ENVIRONMENT=production`).
-- Only required app files copied.
-- Healthcheck on `/health`.
+```yaml

-## CI/CD (Gitea Workflows)
+Points that matter:
 
-Workflows live in `.gitea/workflows/`:
+- Inside the container the server must bind `0.0.0.0` so the published port works. That is
+  allowed only because `MCP_BEARER_TOKEN` or OAuth is configured; otherwise it exits with code 2.
+- The port is published on `127.0.0.1` only. The reverse proxy on the same host is the public
+  entry point.
+- `DATA_DIR` must be a persistent volume writable by the container user. It holds the audit log
+  and the encrypted OAuth token store (`oauth-store.json`, mode 0600). Losing the volume loses
+  all OAuth logins and the audit history. Back it up, and protect the backup like the secrets it
+  protects.
+- Keep `.env` out of version control and out of the image (mode 0600; `setup` writes it that
+  way). Compose passes it as environment, so it is visible to `docker inspect` for anyone with
+  Docker access.
 
-- `lint.yml`: ruff + format checks + mypy.
-- `test.yml`: lint + tests + coverage fail-under `80`.
-- `docker.yml`: lint + test + docker smoke-test gating; image publish on push to `main`/`dev` and on approved PR review targeting `main`/`dev`; tags include commit SHA plus `latest` (`main`) or `dev` (`dev`).
+Check it: `curl http://127.0.0.1:8080/health`.
 
-Docker publish settings:
-- `vars.PUSH_IMAGE=true` enables registry push.
-- `vars.REGISTRY_IMAGE` sets the target image name (for example `registry.example.com/org/aegis-gitea-mcp`).
-- `vars.REGISTRY_HOST` is optional and overrides the login host detection.
-- `secrets.REGISTRY_USER` and `secrets.REGISTRY_TOKEN` are required when push is enabled.
+## Reverse proxy and TLS
 
-## Production Recommendations
+Terminate TLS at a reverse proxy. `PUBLIC_BASE_URL` must be the public https URL (it is required
+for OAuth, and http is only accepted for loopback hosts). Mistral Le Chat needs a valid public
+certificate, and adding a connector there may require workspace admin rights.
 
-- Place MCP behind TLS reverse proxy.
-- Set `PUBLIC_BASE_URL=https://<your-mcp-domain>` so OAuth metadata advertises HTTPS endpoints.
-- Restrict inbound traffic to expected clients.
-- Persist and monitor audit logs.
-- Monitor `/metrics` and auth-failure events.
-- Rotate OAuth client credentials when required.
+Caddy:
+
+```
+gitea-mcp.example.com {
+    reverse_proxy 127.0.0.1:8080 {
+        flush_interval -1
+    }
+}
+```
+
+nginx: inside the proxying `location`, set `proxy_buffering off;` so streamed responses are not
+held back. Also forward `Host` (`proxy_set_header Host $host;`) and keep the default read timeout
+in mind for long tool calls.
+
+The server rejects requests whose `Host` is not allowed (DNS-rebinding protection). Allowed hosts
+are the loopback names with the port, the host of `PUBLIC_BASE_URL`, and `ALLOWED_HOSTS`. If
+you reach it under another name, add that name to `ALLOWED_HOSTS`. With a non-loopback
+`MCP_HOST` (the container) and neither `PUBLIC_BASE_URL` nor `ALLOWED_HOSTS`, every remote `Host`
+is rejected with 421, and the server logs a warning at startup naming the two variables.
+
+The server trusts `X-Forwarded-For` only from `FORWARDED_ALLOW_IPS` (default `127.0.0.1`). When
+the proxy reaches the container from another address, for example a Docker network, add that
+address or network (`FORWARDED_ALLOW_IPS=172.18.0.0/16`). Without it every request looks like it
+comes from the proxy and shares one per-IP rate limit bucket. `*` trusts any peer, so use it only
+when the port is reachable solely from the proxy.
+
+## OAuth application in Gitea
+
+`setup --public-base-url https://gitea-mcp.example.com` registers the application for you as the
+admin's user application. To do it by hand: in Gitea open Settings, Applications, Manage OAuth2
+Applications, create an application named `aegis-gitea-mcp` as a confidential client with the
+redirect URI `https://gitea-mcp.example.com/oauth/callback`, and put the client id and secret in
+`GITEA_OAUTH_CLIENT_ID` and `GITEA_OAUTH_CLIENT_SECRET`. Then set `OAUTH_ENABLED=true`,
+`PUBLIC_BASE_URL` and `TOKEN_ENCRYPTION_KEY` (at least 32 characters, `openssl rand -hex 32`).
+
+Gitea has no instance-wide OAuth application API, so the application belongs to the admin account
+that created it. Re-running setup reuses it; if the stored client secret is missing, Gitea has to
+regenerate it, and setup asks before doing so.
+
+Before the browser is sent to Gitea, the consent page `/oauth/consent` shows the client name and
+the redirect URI, because Gitea remembers consent for this one application and any client can
+register itself. For a public deployment also set `OAUTH_REDIRECT_ALLOWLIST` to the hosted
+clients you use, for example `https://claude.ai/,https://chat.mistral.ai/` (see
+[configuration.md](configuration.md)).
+
+`OAUTH_SCOPES` is the scope list sent to Gitea. Keep it to granular scopes. Narrow it (for
+example to `read:repository,read:issue`) to limit what signed-in users' tokens can do through this
+server regardless of their Gitea rights.
+
+## Upgrades
+
+- Application: pull the new image (or package) and restart. The data volume is kept.
+- `TOKEN_ENCRYPTION_KEY` must stay the same. A store written with another key stops the server
+  at startup (exit code 2, the file is kept) instead of being wiped: restore the old key, or move
+  `DATA_DIR/oauth-store.json` away to start over, which signs every OAuth user out.
+- Upgrading Gitea: tool names and schemas come from the pinned swagger, so a Gitea upgrade does
+  not change them. To pick up a newer API, re-pin the swagger and regenerate the catalog:
+
+  ```bash
+  curl -fsS https://git.example.com/swagger.v1.json -o spec/gitea-swagger.v1.json
+  uv run python scripts/generate_catalog.py
+  uv run python scripts/check_docs.py --write
+  uv run pytest
+  ```
+
+  Review the diff of `tools.json` and `docs/tools.md`: renamed or removed operations change tool
+  names. Until the new spec is pinned, `gitea_api_request` reaches new endpoints.
+
+## CI
+
+The workflows in `.gitea/workflows/` lint, test and build. The `docs-check` job runs
+`uv run python scripts/check_docs.py`, which fails when `docs/tools.md` or the README tool summary
+is stale, or when a document names a tool that does not exist. `scripts/generate_catalog.py
+--check` fails when `tools.json` does not match the pinned swagger.
+
+Security rules of the pipeline:
+
+- Jobs that use the runner's Docker daemon or a secret (`test-integration`, `test-mcp`,
+  `build-and-push`) do not run for pull requests from forks. Access to the daemon is
+  root-equivalent on the host, and a fork controls the workflow and test code. Also enable
+  "require approval for workflows from forks" (or the equivalent runner setting) in Gitea, and
+  keep the daemon of a shared runner free of services you cannot afford to lose.
+- Every third-party action is pinned to a full commit SHA with the version in a trailing
+  comment. Bump a pin deliberately: look up the SHA of the new tag with
+  `git ls-remote https://github.com/<owner>/<action> refs/tags/<tag>` (add `^{}` for annotated
+  tags). The registry token never reaches a third-party action: the CLI reads it from stdin and
+  `uv publish` reads `UV_PUBLISH_PASSWORD`.
+- `build-and-push` scans the built image with a pinned Trivy (`scripts/ci/install_trivy.sh`,
+  sha256 verified) before anything is pushed, and fails on HIGH or CRITICAL findings that have a
+  fix. `scan.yml` repeats the scan and the dependency audit every week, so a new advisory in a
+  pinned base image turns it red: refresh the digests in `docker/Dockerfile`. Accepted findings
+  go in `security/trivyignore.txt` with a waiver row in [security.md](security.md).
+- `publish.yml` needs the `security` job (secret scan, security tests, dependency audit, bandit
+  rules) as well as lint and tests.
+- The image is built under a per-run local tag (`aegis-ci-<run id>-build:<sha>`), scanned under
+  that tag, and the registry tags (`:sha-<12>`, `:dev`, `:latest`, `:main`) are applied only
+  immediately before the push. `build-and-push` needs `lint`, `test-unit`, `test-integration`,
+  `test-mcp` and `security`, so `:dev` and `:latest` are never pushed while one is red.
+- The cleanup script removes containers only for per-run image names (`aegis-ci-<run id>-...`).
+  Registry tags, the `:sha-` tag included, are only untagged.

-# Getting Started
+# Getting started
+
+This page takes you from a fresh clone to a working server in about 5 to 10 minutes, most of it
+creating the Gitea token. It covers the local stdio setup (one user, started by your MCP
+client) and the HTTP server.
 
 ## Prerequisites
 
-- Python 3.10 or higher
-- A running Gitea instance
-- A Gitea OAuth2 application for this MCP server
-- `make` (optional but recommended)
+- Python 3.10 or newer and [uv](https://docs.astral.sh/uv/)
+- A Gitea instance and a site-admin token. In Gitea: Settings, Applications, Generate New
+  Token, then set every scope to Read and Write (or choose `all`). Admin features need a
+  site-admin token. A narrower token still works: calls outside its scopes return Gitea's 403
+  (see "Token scopes" in the [README](../README.md)).
 
-## 1. Install
+## 1. Install and run setup
 
 ```bash
-git clone <repo-url>
+git clone https://git.hiddenden.cafe/Hiddenden/AegisGitea-MCP.git
 cd AegisGitea-MCP
-
-# Install production dependencies
-make install
-
-# Or install with dev dependencies (for testing and linting)
-make install-dev
+uv sync
+uv run aegis-gitea-mcp setup
 ```
 
-To install manually without `make`:
+Setup prompts for the Gitea URL and the token (hidden input). For unattended use pass
+`--gitea-url`, set `GITEA_TOKEN` in the environment and add `--yes`. Options:
+
+| Option | Meaning |
+|---|---|
+| `--gitea-url` | Gitea base URL |
+| `--public-base-url` | Public https URL of this server. Enables registration of the OAuth application |
+| `--no-oauth` | Do not create the Gitea OAuth application |
+| `--env-file` | Env file to create or update (default `AEGIS_ENV_FILE`, else `./.env`) |
+| `--template` | Env template (default `./.env.example`, else the copy built into the package) |
+| `--yes` | Never prompt, and accept regenerating an OAuth client secret |
+
+What it does, in order:
+
+1. Checks that Gitea is reachable (`GET /api/v1/version`) and prints the version. DNS, TLS,
+   timeout and refused-connection failures get a specific hint.
+2. Validates the token (`GET /user`), requires a site administrator, and reads its scopes
+   (`GET /token`). Missing scopes are an error; `all` satisfies everything.
+3. With a public base URL: creates (or reuses, or after confirmation updates) the
+   `aegis-gitea-mcp` OAuth application with redirect URI `<public base URL>/oauth/callback`.
+   Gitea regenerates the client secret on update, which is why it asks first.
+4. Writes the env file atomically with mode 0600. It generates `MCP_BEARER_TOKEN` and
+   `TOKEN_ENCRYPTION_KEY` when they are not there yet, keeps values it does not manage, and
+   tightens the permissions of an existing file.
+5. Prints client configurations for Claude Code, Claude Desktop and Cursor, claude.ai and
+   Mistral Le Chat, a docker-compose service and a Caddyfile.
+
+Secrets are only written to the env file; setup never prints them. It does not follow
+redirects, so the token cannot be sent to a host you did not name.
+
+## 2. Run the server
+
+stdio is started by your MCP client, so you normally do not run it by hand. To check that it
+starts:
 
 ```bash
-python -m venv venv
-source venv/bin/activate        # Linux/macOS
-# or: venv\Scripts\activate     # Windows
-
-pip install -e .
-# dev: pip install -e ".[dev]"
+uv run aegis-gitea-mcp serve
 ```
 
-## 2. Create a Gitea OAuth2 Application
+It waits for JSON-RPC on stdin (stdout is reserved for the protocol, logs go to stderr). Stop it
+with Ctrl+D.
 
-1. In Gitea, open **User Settings > Applications**.
-2. Create an OAuth2 application for AegisGitea-MCP.
-3. Set the redirect URI to `https://<host>/oauth/callback`.
-4. Copy the client ID and client secret.
-
-## 3. Configure
-
-Copy the example environment file and fill in your values:
+For HTTP:
 
 ```bash
-cp .env.example .env
+MCP_TRANSPORT=http uv run aegis-gitea-mcp serve     # or: serve --transport http
+curl http://127.0.0.1:8080/health
 ```
 
-Minimum OAuth settings in `.env`:
+It binds to `127.0.0.1:8080` and serves the MCP endpoint at `/mcp`. Without `MCP_BEARER_TOKEN`
+or OAuth the loopback endpoint is unauthenticated, which is only acceptable for local
+experiments; the server prints a warning. Setup generates `MCP_BEARER_TOKEN` for you.
 
-```env
-GITEA_URL=https://gitea.example.com
-OAUTH_MODE=true
-GITEA_OAUTH_CLIENT_ID=<your-gitea-oauth-client-id>
-GITEA_OAUTH_CLIENT_SECRET=<your-gitea-oauth-client-secret>
-PUBLIC_BASE_URL=https://<host>
-OAUTH_STATE_SECRET=<random-32-byte-minimum-secret>
-```
+## 3. Connect a client
 
-`GITEA_TOKEN` is optional. If it is set, use a narrowly scoped service PAT and only grant it repository access you are prepared to expose after per-user authorization checks. If it is not set, Gitea REST calls use the authenticated user's OAuth token directly.
+Use the snippets that setup printed. They are also in the
+[README](../README.md#client-configuration). Local clients use the stdio configuration with
+`GITEA_URL` and `GITEA_TOKEN` in the client's `env`. Remote clients use
+`https://<your host>/mcp` with the bearer token or OAuth. Before exposing the server beyond
+localhost, read [deployment.md](deployment.md) and [hardening.md](hardening.md).
 
-See [Configuration](configuration.md) for the full list of settings.
+## 4. Try it
 
-## 4. Optional Standard API Key Mode
-
-For non-OAuth deployments, configure `GITEA_TOKEN` and `MCP_API_KEYS`. Generate an API key with:
+Ask the client something that needs a tool, for example "list my repositories". Every result
+names the identity that made the call. To check the audit trail:
 
 ```bash
-make generate-key
-# or: python scripts/generate_api_key.py
+make validate-audit
 ```
 
-Copy the printed key into `MCP_API_KEYS` in your `.env` file and set `OAUTH_MODE=false`.
+## Running without a clone
 
-## 5. Run
+With `uvx`, no checkout is needed:
 
 ```bash
-make run
-# or: python -m aegis_gitea_mcp.server
+GITEA_URL=https://git.example.com GITEA_TOKEN=<your-gitea-token> \
+  uvx --index https://git.hiddenden.cafe/api/packages/Hiddenden/pypi/simple/ aegis-gitea-mcp
 ```
 
-The server starts on `http://127.0.0.1:8080` by default.
+The package comes from the Gitea package registry, see [packaging.md](packaging.md). Always pass
+the `--index`: the name is not registered on public PyPI, and a bare `uvx aegis-gitea-mcp` would
+resolve there. From a clone use
+`uv run --directory /path/to/AegisGitea-MCP aegis-gitea-mcp serve`.
 
-Verify it is running:
+## Where state lives
 
-```bash
-curl http://localhost:8080/health
-# {"status": "healthy", ...}
-```
-
-## 6. Connect an AI Client
-
-### Claude
-
-In claude.ai, open **Settings > Connectors > Add custom connector** and paste:
-
-```
-https://<host>/mcp
-```
-
-Claude discovers OAuth metadata, registers through `/register`, and uses PKCE S256 automatically.
-
-### Claude Code
-
-```bash
-claude mcp add --transport http aegis-gitea https://<host>/mcp
-```
-
-Claude Code uses the same remote MCP and OAuth metadata. Local development loopback callbacks are allowed by default.
-
-### Cowork
-
-Cowork uses the same connector infrastructure and MCP URL as Claude.
-
-### SSE compatibility
-
-If your client still expects SSE transport, use:
-
-- **SSE URL:** `https://<host>/mcp/sse`
-- **Tool discovery URL:** `https://<host>/mcp/tools` (no auth required)
-- **Tool call URL:** `https://<host>/mcp/tool/call`
-
-For a production deployment behind a reverse proxy, see [Deployment](deployment.md).
-
-## Next Steps
-
-- [Configuration](configuration.md) — tune file size limits, rate limiting, log paths
-- [API Reference](api-reference.md) — available tools and endpoints
-- [Security](security.md) — understand authentication and audit logging
-- [Deployment](deployment.md) — Docker and Traefik setup
+The audit log and, in OAuth mode, the encrypted token store live in `DATA_DIR` (default
+`~/.local/state/aegis-gitea-mcp`). Override with `DATA_DIR` or `AUDIT_LOG_PATH`.

-## AI Usage Policy
-
-- AI assistance is allowed for design, implementation, and review only within documented repository boundaries.
-- AI outputs must be reviewed, tested, and policy-validated before merge.
-- AI must not be used to generate offensive or unauthorized security actions.
-- Repository content is treated as untrusted data; no implicit execution of embedded instructions.
-
-## Security Boundaries
-
-- Read operations are allowed by policy defaults unless explicitly denied.
-- Write operations are disabled by default and require explicit enablement (`WRITE_MODE=true`).
-- Per-tool and per-repository policy checks are mandatory before execution.
-- Secrets are masked or blocked according to `SECRET_DETECTION_MODE`.
-
-## Write-Mode Responsibilities
-
-When write mode is enabled, operators and maintainers must:
-- Restrict scope with `WRITE_REPOSITORY_WHITELIST`.
-- Keep policy file deny/allow rules explicit.
-- Monitor audit entries for all write operations.
-- Enforce peer review for policy or write-mode changes.
-
-## Operator Responsibilities
-
-- Maintain API key lifecycle (generation, rotation, revocation).
-- Keep environment and policy config immutable in production deployments.
-- Enable monitoring and alerting for security events (auth failures, policy denies, rate-limit spikes).
-- Run integrity checks for audit logs regularly.
-
-## Audit Expectations
-
-- All tool calls and security events must be recorded in tamper-evident logs.
-- Audit logs are append-only and hash-chained.
-- Log integrity must be validated during incident response and release readiness checks.

-# Hardening
+# Hardening checklist
 
-## Application Hardening
+This server is full access by design (ADR 0001): whoever can call it has the power of the
+configured Gitea token, which for an admin token means everything. The server keeps a few
+invariants (audit, secret redaction, bounded output, validated input, fail-closed HTTP
+authentication), but it does not decide what is safe. This checklist is how you do that.
 
-- Secure defaults: localhost bind, write mode disabled, policy-enforced writes.
-- Strict config validation at startup.
-- Redacted secret handling in logs and responses.
-- Policy deny/allow model with path restrictions.
-- Non-leaking production error responses.
+## Decide what to expose
 
-## Container Hardening
+- Create the Gitea token with the narrowest scopes that do the job. Full access needs a
+  site-admin token with `all`; a read-only assistant needs only read scopes. The token is the
+  hard limit, because Gitea enforces it.
+- Prefer per-user OAuth to a shared admin token whenever more than one person connects: each
+  user then acts under their own Gitea permissions and admin tools fail for non-admins.
+- Narrow what is listed: `READ_ONLY=true`, `TOOLSETS=...`, `DISABLED_TOOLS=...`. Hide what the
+  assistant never needs: `admin`, `actions` (secrets), `hook`, `user` (tokens, keys) and the
+  delete tools are the sensitive ones. `gitea_api_request` can reach any endpoint, so on a
+  restricted profile drop `misc` or disable it.
+- Keep `OAUTH_SCOPES` as narrow as the use case allows.
+- Do not use Sudo-capable tokens for clients that do not need to impersonate users.
 
-- Non-root runtime user.
-- `no-new-privileges` and dropped Linux capabilities.
-- Read-only filesystem where practical.
-- Explicit health checks.
-- Separate dev and production compose profiles.
+## Treat the credentials as keys to the instance
 
-## Operational Hardening
+- `GITEA_TOKEN` and `MCP_BEARER_TOKEN` are equivalent in power on HTTP. Generate the bearer
+  token with `openssl rand -hex 32`, store it in a secret manager or a mode 0600 env file, rotate
+  it when someone leaves, and never put it in a URL (it only goes in the `Authorization`
+  header).
+- `TOKEN_ENCRYPTION_KEY` protects the stored per-user tokens. Keep it separate from the data
+  volume backups. `GITEA_OAUTH_CLIENT_SECRET` likewise.
+- Use `setup`, which writes the env file with mode 0600 and never prints secrets. The server
+  loads `./.env` only while it is a regular file you own with mode 0600; keep it elsewhere with
+  `--env-file` or `AEGIS_ENV_FILE`.
+- For a public OAuth deployment set `OAUTH_REDIRECT_ALLOWLIST` (for example
+  `https://claude.ai/,https://chat.mistral.ai/`), so only the hosted clients you use can
+  register, and leave `MCP_BEARER_TOKEN` and `GITEA_TOKEN` unset when nobody needs the admin
+  identity.
+- Do not paste tokens into chat with the assistant, and do not commit `.env`.
 
-- Rotate API keys regularly.
-- Minimize Gitea bot permissions.
-- Keep policy file under change control.
-- Alert on repeated policy denials and auth failures.
+## Network and transport
+
+- Keep the default bind `127.0.0.1`. Publish the container port on `127.0.0.1` and put a reverse
+  proxy with TLS in front. A non-loopback bind refuses to start without authentication; do not
+  work around it.
+- Terminate TLS with a valid certificate. `PUBLIC_BASE_URL` must be https.
+- Set `ALLOWED_HOSTS` to exactly the host names you serve. Requests with other `Host` values are
+  rejected.
+- Restrict who can reach the endpoint at the proxy or firewall too (VPN, allow list), as a
+  second layer in front of bearer authentication.
+- Set `FORWARDED_ALLOW_IPS` to the proxy address only (not `*`), so a client cannot spoof its IP.
+- Leave `RATE_LIMIT_PER_MINUTE` on. Put request-size and connection limits at the proxy.
+- Use https for `GITEA_URL`. Plain http sends the token unencrypted (setup warns about it).
+
+## Container and host
+
+- Run the image as the non-root user, `read_only: true` with a `tmpfs` for `/tmp`,
+  `cap_drop: ALL` and `no-new-privileges`, as the compose snippet in
+  [deployment.md](deployment.md) does.
+- Mount only the data volume. Give it to the service account alone (mode 0700).
+- Pin the image by digest in production, and update regularly.
+- Do not run the stdio server with a token that is broader than the user's own needs on a shared
+  machine: any process of that user can read the client configuration.
+
+## Audit and monitoring
+
+- Ship the audit log off the host and validate the chain regularly
+  ([audit-logging.md](audit-logging.md)).
+- Alert on repeated `forbidden` or `unauthorized` outcomes and on calls to admin, secret and
+  delete tools.
+- Keep `LOG_LEVEL=INFO` and `EXPOSE_ERROR_DETAILS=false` in production.
+- Keep `SECRET_DETECTION_MODE=mask` (or `block`). Secret detection is a safety net with regular
+  expressions, not a guarantee.
+
+## Untrusted content
+
+- Keep tool-call confirmation enabled in the client for destructive tools. Prompt injection in
+  issues, pull requests, comments and files is the realistic way a model is tricked into using
+  the access it has.
+- Do not connect a write-capable, broad-scope profile to an assistant that also reads untrusted
+  content from other sources.
+- Prefer separate profiles: a read-only one for browsing and triage, a write-capable one that
+  you use deliberately.

-AegisGitea MCP is a security-first [Model Context Protocol (MCP)](https://modelcontextprotocol.io) server that provides controlled AI access to self-hosted Gitea repositories.
+AegisGitea MCP is a full-access [Model Context Protocol](https://modelcontextprotocol.io) bridge
+to the whole Gitea API: one tool per operation of the pinned Gitea 28.1.0 swagger (537) plus
+`gitea_api_request`, 538 tools in total. It serves them over stdio and streamable HTTP, with
+admin-token and per-user OAuth authentication, a hash-chained audit log and bounded, secret-masked
+results. Everything is enabled by default; you restrict it with configuration and the scope of
+the Gitea token.
 
-## Overview
+Gitea content is untrusted: results are labelled as data and clients must never treat them as
+instructions (see the [README](../README.md#security-notice-gitea-content-is-untrusted)).
 
-AegisGitea MCP acts as a secure bridge between AI assistants (such as Claude, Claude Code, or Cowork) and your Gitea instance. It exposes read tools and opt-in write tools while enforcing per-user OAuth, repository authorization, policy checks, rate limiting, and tamper-evident audit logging.

-# Local quickstart (stdio)
-
-The local transport runs AegisGitea-MCP on your own machine as a single-user MCP
-server over stdio. It authenticates with **your** Gitea Personal Access Token
-(PAT) — there is no OAuth, no public endpoint, and no web stack to install.
-
-## What you need
-
-- A Gitea instance URL (`GITEA_URL`).
-- A Gitea Personal Access Token (`GITEA_TOKEN`) with least privilege:
-  - `read:repository`
-  - `write:repository` only if you intend to enable `WRITE_MODE`.
-- [`uv`](https://docs.astral.sh/uv/) (for `uvx`) or `pip`.
-
-## Run it
-
-With `uvx` (no install):
-
-```bash
-GITEA_URL=https://git.hiddenden.cafe \
-GITEA_TOKEN=<pat> \
-uvx aegis-gitea-mcp
-```
-
-With pip:
-
-```bash
-pip install aegis-gitea-mcp
-GITEA_URL=https://git.hiddenden.cafe GITEA_TOKEN=<pat> aegis-gitea-mcp
-```
-
-A local `.env` file is also supported — drop `GITEA_URL` and `GITEA_TOKEN` in it
-and just run `aegis-gitea-mcp`.
-
-If a required variable is missing the server exits with a clear message instead
-of a traceback.
-
-## Wire it into a client
-
-Claude Code:
-
-```bash
-claude mcp add aegis-gitea \
-  -e GITEA_URL=https://git.hiddenden.cafe \
-  -e GITEA_TOKEN=<pat> \
-  -- uvx aegis-gitea-mcp
-```
-
-Claude Desktop (`claude_desktop_config.json`):
-
-```json
-{
-  "mcpServers": {
-    "aegis-gitea": {
-      "command": "uvx",
-      "args": ["aegis-gitea-mcp"],
-      "env": {
-        "GITEA_URL": "https://git.hiddenden.cafe",
-        "GITEA_TOKEN": "<pat>"
-      }
-    }
-  }
-}
-```
-
-## What still applies locally
-
-The local adapter is single-user and trusts the PAT owner, so it skips the
-per-user repository-permission probe used by the public server. Everything else
-is identical to the server:
-
-- **Policy engine** (`policy.yaml`) — same allow/deny rules.
-- **`WRITE_MODE`** — off by default; writes are denied unless explicitly enabled
-  and whitelisted.
-- **`gitea_request`** full-API escape hatch — same write classifier, known-path
-  gate, and admin/credential denylist.
-- **Secret sanitization** of tool output.
-- **Tamper-evident audit log** — written to a per-user path when the container
-  default is not writable:
-  - Windows: `%LOCALAPPDATA%\aegis-gitea-mcp\audit.log`
-  - Linux/macOS: `$XDG_STATE_HOME/aegis-gitea-mcp/audit.log` or
-    `~/.local/state/aegis-gitea-mcp/audit.log`
-  - Override with `AUDIT_LOG_PATH`.
-
-## Enabling writes locally
-
-Writes are opt-in, exactly as on the server:
-
-```bash
-GITEA_URL=https://git.hiddenden.cafe \
-GITEA_TOKEN=<pat-with-write-repository> \
-WRITE_MODE=true \
-WRITE_REPOSITORY_WHITELIST=acme/app,acme/docs \
-uvx aegis-gitea-mcp
-```
-
-See [configuration.md](configuration.md) for the full variable reference and
-[write-mode.md](write-mode.md) for the write-mode model.

-## Logging
-
-- Structured JSON logs.
-- Request correlation via `X-Request-ID`.
-- Security events and policy denials are audit logged.
-
-### Structured event helpers
-
-`logging_utils` exposes reusable helpers so endpoints emit consistent,
-secret-safe structured events instead of ad-hoc inline logging:
-
-- `log_event(logger, level, event, **context)` — emit a named event with a
-  `context` mapping; keys in `SENSITIVE_CONTEXT_KEYS` (e.g. `token`,
-  `authorization`, `password`) are masked as `***`.
-- `log_nullable_field(logger, event, field, value)` — record whether a parsed
-  response field is `None` and its runtime type, without dumping its contents.
-- `sanitize_context(context)` — the masking primitive used by the above.
-
-The `context` mapping is serialized into the JSON log payload under a `context`
-key. These run at `DEBUG`, so they are silent unless `LOG_LEVEL=DEBUG`.
-
-`get_issue` is instrumented with these helpers (`get_issue.start`,
-`get_issue.payload_shape`, `get_issue.field_check`) to make nullable-field
-parsing failures diagnosable. The same pattern can be reused for other
-parsing-heavy endpoints (`get_pull_request`, `list_issues`, `get_commit_diff`).
-
-## Metrics
-
-Prometheus-compatible endpoint: `GET /metrics`.
-
-Current metrics:
-- `aegis_http_requests_total{method,path,status}`
-- `aegis_tool_calls_total{tool,status}`
-- `aegis_tool_duration_seconds_sum{tool}`
-- `aegis_tool_duration_seconds_count{tool}`
-
-## Tracing and Correlation
-
-- Request IDs propagate in response header (`X-Request-ID`).
-- Tool-level correlation IDs included in MCP responses.
-
-## Operational Guidance
-
-- Alert on spikes in 401/403/429 rates.
-- Alert on repeated `access_denied` and auth-rate-limit events.
-- Track tool latency trends for incident triage.

-## Distribution layout
+## What is in the package
 
-Each channel ships one distribution with two console scripts and one optional
-extra (the stable and dev packages are identical here — only the dist name and
-version differ):
+One distribution, one console script:
 
-| Console script | Entry point | Requires |
-|----------------|-------------|----------|
-| `aegis-gitea-mcp` | `aegis_gitea_mcp.stdio_app:main` | core only |
-| `aegis-gitea-mcp-server` | `aegis_gitea_mcp.server_entry:main` | `[server]` extra |
+| Console script | Entry point |
+|---|---|
+| `aegis-gitea-mcp` | `aegis_gitea_mcp.cli:main` (subcommands `serve`, `setup`, `version`; `serve` is the default) |
 
-- **Core** (default install): `httpx`, `pydantic`, `pydantic-settings`, `PyYAML`,
-  `python-dotenv`, `structlog`, `mcp`. Enough to run the local stdio server.
-- **`[server]` extra**: `fastapi`, `uvicorn[standard]`, `PyJWT[crypto]`,
-  `python-multipart`. The public HTTP/OAuth server.
-
-The `aegis-gitea-mcp-server` entry point degrades gracefully: invoked without
-the web stack it prints `install 'aegis-gitea-mcp[server]'` instead of a
-`ModuleNotFoundError` traceback.
+Dependencies are the `mcp` SDK (2.3 or newer, below 3), `httpx`, `pydantic`, `pydantic-settings`,
+`jsonschema`, `cryptography` and `uvicorn`. There are no extras: both transports and per-user
+OAuth are in the default install. The generated tool catalog (`catalog/tools.json`) ships inside
+the package.

-(With `pip`, use `--index-url` the same way.) Both packages expose the same
-`aegis-gitea-mcp` / `aegis-gitea-mcp-server` console scripts and the same
-`aegis_gitea_mcp` import module, so install one **or** the other per environment.
+The registry holds only this project's packages and does not proxy PyPI, so it is added with
+`--index` and the dependencies (`mcp`, `httpx`, ...) still come from PyPI. uv's default index
+strategy (`first-index`) takes a package from the first index that has it and never mixes
+versions across indexes, so with `--index` the name `aegis-gitea-mcp` is always taken from
+this registry, even if somebody registers it on PyPI.
 
-## Publishing channels
+Do not use `--extra-index-url` with `pip`. It merges the indexes, and `pip` picks the highest
+version from either: whoever publishes `aegis-gitea-mcp` on PyPI with a higher version number
+wins (dependency confusion), and the package would run with your Gitea token in its
+environment. With `pip`, fetch the wheel from this registry alone, then install it:
 
-Publishing is merge-driven, not tag-driven. The publish workflow
-(`.gitea/workflows/publish.yml`) triggers on a push to `dev` or `main`, runs
-lint + tests first, then builds with `uv` and publishes to the Gitea PyPI
-registry. The package name + version are patched into `pyproject.toml` **at build
-time only** (never committed):
+```bash
+pip download --no-deps --index-url https://git.hiddenden.cafe/api/packages/Hiddenden/pypi/simple/ aegis-gitea-mcp -d wheels/
+pip install wheels/aegis_gitea_mcp-*.whl
+```
 
-- **`dev` push** → `aegis-gitea-mcp-dev` at `X.Y.Z.dev<run_number>`. The CI run
-  number is monotonic, so every merge to `dev` yields a unique pre-release.
-- **`main` push** → `aegis-gitea-mcp` at the plain `X.Y.Z` from `pyproject.toml`.
-  Publishing uses `uv publish --check-url`, so a `main` push that did **not** bump
-  the version is a clean no-op (the existing files are skipped) rather than a 409.
+The name is not registered on public PyPI. Publishing there is intentionally not configured, but
+the owner should reserve both names (`aegis-gitea-mcp`, `aegis-gitea-mcp-dev`) on PyPI so nobody
+else can take them. Until then every install command above must name the index.
+
+To run from a clone instead of a registry:
+`uv run --directory /path/to/AegisGitea-MCP aegis-gitea-mcp serve`.
+
+## Publishing
+
+Publishing is merge-driven, not tag-driven. `.gitea/workflows/publish.yml` triggers on a push to
+`dev` or `main`, runs the lint and test gates first, builds with `uv build`, and publishes with
+`uv publish`. The package name and version are patched into `pyproject.toml` at build time only
+and never committed.
+
+- A push to `dev` publishes `aegis-gitea-mcp-dev` at `X.Y.Z.dev<run number>`, unique per run.
+- A push to `main` publishes `aegis-gitea-mcp` at the plain `X.Y.Z`. `uv publish --check-url`
+  skips files that already exist, so a push that did not bump the version is a clean no-op.
 
 ### Cutting a stable release
 
-1. Bump `version` in `pyproject.toml` (e.g. `0.2.0` → `0.3.0`) on a branch off
-   `dev`.
-2. Open a PR into `dev` and merge it (this publishes a fresh
-   `aegis-gitea-mcp-dev` build).
-3. Promote `dev` → `main`. The push to `main` publishes the new stable
-   `aegis-gitea-mcp X.Y.Z`.
+1. Bump `version` in `pyproject.toml` on a branch off `dev`.
+2. Open a pull request into `dev` and merge it. That publishes a fresh dev build.
+3. Promote `dev` to `main`. The push to `main` publishes the stable version.
 
-Re-pushing `main` at an unchanged version is harmless — `--check-url` skips the
-already-published files.
+### CI secret
 
-### Required CI secrets
+Publishing uses the `REGISTRY_TOKEN` Actions secret, a personal access token with
+`write:package`, the same one the image build uses. The token authenticates as its owner, so the
+job's actor is the username and the token is the password. If the secret is missing the job
+fails instead of publishing anonymously.
 
-The publish job reuses the **existing** `REGISTRY_TOKEN` Actions secret — the same
-PAT (`write:package`) that `docker.yml` uses to push images — so no new secret is
-needed. The token authenticates as its owning Gitea user, so `GITHUB_ACTOR` is the
-username and the token is the password.
-
-| Secret | Purpose |
-|--------|---------|
-| `REGISTRY_TOKEN` | PAT with `write:package`; used for both image and package pushes |
-
-If the secret is absent the job fails loudly rather than publishing anonymously.
-

-# Policy Engine
-
-## Overview
-
-Aegis uses a YAML policy engine to authorize tool execution before any Gitea API call is made.
-
-## Behavior Summary
-
-- Global tool allow/deny supported.
-- Per-repository tool allow/deny supported.
-- Optional repository path allow/deny supported.
-- Write operations are denied by default.
-- Write operations also require `WRITE_MODE=true` and either:
-  - `WRITE_REPOSITORY_WHITELIST` match, or
-  - `WRITE_ALLOW_ALL_TOKEN_REPOS=true`.
-
-## Example Configuration
-
-```yaml
-defaults:
-  read: allow
-  write: deny
-
-tools:
-  deny:
-    - search_code
-
-repositories:
-  acme/service-a:
-    tools:
-      allow:
-        - get_file_contents
-        - list_commits
-    paths:
-      allow:
-        - src/*
-      deny:
-        - src/secrets/*
-```
-
-## Failure Behavior
-
-- Invalid YAML or invalid schema: startup failure (fail closed).
-- Denied tool call: HTTP `403` + audit `access_denied` entry.
-- Path traversal attempt in path-scoped tools: denied by validation/policy checks.
-
-## Operational Guidance
-
-- Keep policy files version-controlled and code-reviewed.
-- Prefer explicit deny entries for sensitive tools.
-- Use repository-specific allow lists for high-risk environments.
-- Test policy updates in staging before production rollout.

-# Raw API Dispatch (`gitea_request`)
+# Raw API tool: `gitea_api_request`
 
-`gitea_request` is a generic escape hatch that can call **any** Gitea REST
-endpoint by method and path. It exists for the long tail of the Gitea API that
-the curated, typed tools do not cover (merging PRs, reviews, writing files,
-webhooks, branch/tag protections, collaborators, Actions/CI, packages,
-notifications, and so on).
+`gitea_api_request` sends one request to any Gitea API endpoint. It exists for endpoints that are
+newer than the pinned Gitea 28.1.0 swagger, so a Gitea upgrade does not have to wait for a
+catalog update. Prefer the generated tools whenever one exists: they have typed arguments, hints
+and validation.
 
-> Prefer the dedicated tools whenever one exists. Use `gitea_request` only for
-> endpoints they do not cover. It is subject to policy, write-mode, and the
-> sensitive-path denylist described below.
+It is a hand-written tool, not part of the generated catalog, and belongs to the `misc` domain.
+It is annotated as not read-only and destructive.
 
 ## Arguments
 
-| Field | Type | Notes |
-|-------|------|-------|
-| `method` | enum | `GET`, `HEAD`, `POST`, `PUT`, `PATCH`, `DELETE` (case-insensitive). Any other method is rejected before any network call. |
-| `path` | string | Gitea REST path. The `/api/v1` prefix is optional. A full URL may be supplied — the host and query string are stripped. |
-| `query` | object | Optional query-string parameters. |
-| `body` | object | Optional JSON request body. **Never logged.** |
+| Argument | Type | Rules |
+|---|---|---|
+| `method` | string | `GET`, `POST`, `PUT`, `PATCH` or `DELETE`. Required. |
+| `path` | string | Required. Starts with `/`, relative to `/api/v1`, at most 2048 characters. |
+| `query` | object | Optional. Values are strings, numbers, booleans or arrays of them. |
+| `body` | any JSON | Optional request body. |
+| `sudo` | string | Optional Gitea login to act as (site-admin tokens only), as for every tool. |
 
-The response is returned in a stable envelope:
+Unknown arguments are rejected. The path is checked: no empty, `.` or `..` segments, and no
+backslash, `?`, `#`, `%` or control characters (put parameters in `query`). A body is never
+logged or returned. The `token`, `access_token` and `sudo` query parameters are refused,
+because credentials belong in the identity, not in the URL.
+
+## Behaviour
+
+- It goes through the same executor as every generated tool: the identity's token, no redirects,
+  response limits, redaction and secret masking, the result envelope and the same audit entries (`tool_call_started`, then `tool_invocation`).
+- There is no allow list of paths and no write classification: with full access, the token's
+  scopes and the identity's Gitea permissions are the limit.
+- `READ_ONLY=true` keeps the tool listed but it accepts only `GET`.
+- `TOOLSETS` without `misc`, or `DISABLED_TOOLS=gitea_api_request`, removes it.
+- The audit entry records the method and the path, so it is visible which endpoint was called.
+
+## Example
 
 ```json
 {
   "method": "GET",
-  "path": "/api/v1/repos/acme/app/pulls/1",
-  "write": false,
-  "repository": "acme/app",
-  "data": { "...": "..." }
+  "path": "/repos/acme/app/issues",
+  "query": {"state": "open", "limit": 10}
 }
 ```
 
-List responses add `count` and `omitted`; oversized objects are returned as a
-truncated JSON string with `"truncated": true`. All responses are bounded by
-`MAX_TOOL_RESPONSE_ITEMS` / `MAX_TOOL_RESPONSE_CHARS`.
-
-## Two-layer authorization
-
-A single tool surface would normally collapse the granularity of `policy.yaml`.
-To preserve it, every call is authorized twice:
-
-1. **Central gate (`server.py`).** The registered `gitea_request` tool name is
-   allowed/denied like any other tool. In service-PAT mode the central gate also
-   parses the target repository from the path and verifies that the signed-in
-   user has permission on that repository before the service PAT is used.
-2. **Handler gate (`raw_tools.py`).** The handler derives a coarse **virtual
-   tool name** of the form `gitea_request:<METHOD>:<top-path-segment>` (for
-   example `gitea_request:GET:repos` or `gitea_request:DELETE:repos`) and runs
-   it back through the policy engine with the parsed repository, target path, and
-   a `is_write` flag (`true` for any method other than GET/HEAD). This reuses the
-   existing write-mode + write-whitelist enforcement and lets `policy.yaml` allow
-   or deny raw dispatch per method and per top-level path segment.
-
-Because the policy engine matches tool names by **exact set membership** (only
-`paths` use globbing), the virtual name is deliberately coarse and stable.
-
-### Example: lock raw dispatch to reads
-
-```yaml
-tools:
-  deny:
-    - gitea_request:POST:repos
-    - gitea_request:PUT:repos
-    - gitea_request:PATCH:repos
-    - gitea_request:DELETE:repos
-```
-
-## Sensitive-path denylist
-
-Independently of `policy.yaml`, the handler blocks endpoints that touch an
-admin or credential surface **for every method, including GET** (a GET on these
-already leaks credentials or privileged configuration):
-
-- `/admin`
-- `*tokens*`
-- `*secrets*`
-- `*hooks*`
-- `*keys*` (and `*gpg_keys*`)
-- `applications/oauth2`
-- `actions/runners/registration-token`
-
-This denylist lives in the handler and **cannot be re-opened from
-`policy.yaml`.** It is overridden only by setting `RAW_API_ALLOW_SENSITIVE=true`.
-
-## Configuration
-
-| Variable | Default | Notes |
-|----------|---------|-------|
-| `RAW_API_ENABLED` | `true` | Killswitch. When `false`, `gitea_request` refuses every dispatch with a `403`. |
-| `RAW_API_ALLOW_SENSITIVE` | `false` | When `true`, the admin/credential denylist is bypassed. Leave `false` unless you fully understand the exposure. |
-
-## Security warning
-
-> With `WRITE_MODE=true`, the **write whitelist is the only brake** on
-> `POST`/`PUT`/`PATCH`/`DELETE` across the *entire* Gitea API surface reachable
-> by `gitea_request`. Any write method against a whitelisted repository will be
-> attempted. Keep the whitelist tight, prefer denying the write virtual tool
-> names in `policy.yaml`, and keep `RAW_API_ALLOW_SENSITIVE=false`.
-
-## Behavioral notes and edge cases
-
-- **Full URL supplied instead of a path:** only the path is used; the host and
-  query string are discarded (`query` carries query parameters).
-- **Path traversal (`..`):** rejected during argument validation (`400`).
-- **Unknown / non-HTTP method:** rejected during argument validation, before any
-  network call.
-- **Cross-repo endpoints** such as `/repos/search` and `/repos/issues/search`
-  are intentionally *not* treated as repository-scoped, so `repository` is
-  `null` for them.
-- **Non-repository writes** such as `POST /user/repos` or `POST /orgs` are denied
-  with *"write operation requires a repository target"*. This is the secure
-  default — the per-user permission model is repository-scoped, so there is no
-  repository against which to verify the write. This behavior is intentional and
-  is not worked around.
-- **Service-PAT mode:** non-repository endpoints (for example `GET /user/orgs`)
-  are denied by the central gate because per-user permission can only be verified
-  against a repository target. Use the dedicated tools for those, or run in
-  OAuth-only mode.
+The result is the usual envelope, with `request.path` set to the path that was called and the
+response under `data`. Content under `data` is untrusted, as everywhere.

 # Roadmap
 
-## High-Level Evolution Plan
+Where the project stands and what is deliberately not planned. Design decisions are in
+[docs/adr](adr/0001-full-access-by-default.md).
 
-1. Hardened read-only gateway baseline.
-2. Policy-driven authorization and observability.
-3. Controlled write-mode rollout.
-4. Automation and event-driven workflows.
-5. Continuous hardening and enterprise controls.
-6. Dual transport (HTTP/OAuth + local stdio) on a shared core, with safe
-   full-API coverage and resource-type-aware authorization (0.2.0).
+## 1.0.0
 
-## Threat Model Updates
+1.0.0 is a breaking rebuild of 0.x:
 
-- Primary threats: credential theft, over-permissioned automation, prompt injection via repo data, policy bypass, audit tampering.
-- Secondary threats: denial-of-service, misconfiguration drift, unsafe deployment defaults.
+- one tool per operation of the pinned Gitea 28.1.0 swagger (537) plus `gitea_api_request`;
+- stdio and streamable HTTP on the official `mcp` SDK;
+- admin-token mode and per-user OAuth with dynamic client registration;
+- a `setup` command, a generated tool inventory and a docs drift check in CI;
+- live-Gitea integration tests and MCP smoke tests in CI.
 
-## Security Model
+The gates that 0.x used to restrict a shared service token (write opt-in, a policy file, per-resource
+checks) are gone, together with the old web adapter and its extras (ADR 0001, 0006). All tool names
+changed to `gitea_<domain>_<action>`.
 
-- API key authentication + auth failure throttling.
-- Per-IP and per-token request rate limits.
-- Secret detection and outbound sanitization.
-- Tamper-evident audit logs with integrity verification.
-- No production stack-trace disclosure.
+## Known limits
 
-## Policy Model
+- Tool list size. 538 tools is a lot for clients without tool search. Use `TOOLSETS`,
+  `READ_ONLY` and `DISABLED_TOOLS` for a slim profile. How claude.ai and Mistral Le Chat cope
+  with the full list is to be confirmed against the real clients.
+- Gitea has no queue management, no instance configuration writes and no instance-wide OAuth
+  application endpoints, so there are no tools for them.
+- The catalog follows one pinned swagger. A newer Gitea needs a re-pin and regeneration, and
+  `gitea_api_request` covers the gap in the meantime.
+- Some operations need state that is hard to reproduce in CI (a registered runner executing a
+  job, a reachable remote for mirrors and migrations, uploaded packages). The integration sweep
+  calls every tool, and asserts Gitea's documented response where a full happy path is not
+  reproducible.
+- In OAuth mode the server holds per-user Gitea tokens, encrypted at rest. That store is the most
+  sensitive asset after the admin token.
 
-- YAML policy with global and per-repository allow/deny rules.
-- Optional path restrictions for file-oriented tools.
-- Default write deny.
-- Write-mode repository whitelist enforcement.
+## Not planned
 
-## Capability Matrix Concept
+- A policy engine or per-repository allow lists inside the server. Restrict with the token's
+  scopes, per-user OAuth and the tool filters.
+- Metrics endpoints, webhook ingest and scheduled jobs. This is an API bridge.
+- Scraping the Gitea web UI for features the API lacks.
 
-- `Read` capabilities: enabled by default but policy-filtered.
-- `Write` capabilities: disabled by default, policy + whitelist gated.
-- `Automation` capabilities: disabled by default, policy-controlled.
+## Possible later work
 
-## Audit Log Design
-
-- JSON lines.
-- `prev_hash` + `entry_hash` chain.
-- Correlation/request IDs for traceability.
-- Validation script for chain integrity.
-
-## Write-Mode Architecture
-
-- Separate write tool set with strict schemas.
-- Global toggle (`WRITE_MODE`) + per-repo whitelist.
-- Policy engine still authoritative.
-- No merge, branch deletion, or force push endpoints.
-
-## Deployment Architecture
-
-- Non-root container runtime.
-- Read-only filesystem where practical.
-- Explicit opt-in for insecure bind.
-- Separate dev and prod compose profiles.
-
-## Observability Architecture
-
-- Structured JSON logs with request correlation.
-- Prometheus-compatible `/metrics` endpoint.
-- Tool execution counters and duration aggregates.
-
-## Risk Analysis
-
-- Highest risk: write-mode misuse and policy misconfiguration.
-- Mitigations: deny-by-default, whitelist, audit chain, tests, docs, reviews.
-
-## Extensibility Notes
-
-- Add new tools only through schema + policy + docs + tests path.
-- Keep transport-agnostic execution core for webhook/scheduler integrations.
+- Re-pinning to newer Gitea releases as they ship.

+Review of commit `ce5ae6c` on `feat/full-api-coverage`, 2026-10-14. Scope: every path from an
+HTTP request or a stdio message to a Gitea call (`transports.py`, `auth.py`, `server.py`,
+`oauth/*`, `gitea/*`, `rate_limit.py`, `config.py`), audit and logging, `setup_cmd.py`, the
+Docker image and CI. The threat model is in [security.md](security.md). S2 fixes these
+findings and adds the negative tests to `tests/security/`.
+
+Severity: critical, high, medium, low. Reproduction scripts referenced below were run in a
+scratch directory against the code as committed; each fix lists the negative test that proves
+it.
+
+## Summary
+
+| Id | Severity | Title | Status (S2) |
+|---|---|---|---|
+| SEC-01 | high | Unbounded request body on the unauthenticated consent POST | fixed |
+| SEC-02 | medium | Stored webhook `authorization_header` returned by hook read tools | fixed |

+| SEC-05 | medium | Any https redirect URI can be registered; the consent page is the only barrier | fixed, default waived (W-10) |

+| SEC-09 | low | OAuth pre-sign-in state can be flushed by unauthenticated floods | fixed |
+| SEC-10 | low | `GITEA_URL` and `PUBLIC_BASE_URL` accept whitespace and control characters; plain http Gitea is silent | fixed |
+| SEC-11 | low | Audit log created with umask defaults; unkeyed hash chain | fixed, keyed chain waived (W-11) |
+| SEC-12 | low | Tool audit entries do not record the client, session or source IP | fixed |
+| SEC-13 | low | Token store directory ownership is not verified | fixed |
+| SEC-14 | low | CI cleanup and credential handling on the shared Docker daemon | fixed |
+| SEC-15 | low | `tests/security` missing, so the CI `security` job fails; publish is not gated on it | fixed |
+| SEC-16 | low | No container image vulnerability scan | fixed |
+| SEC-17 | low | Consent POST accepts a missing `Origin` header, unlike ADR 0004 says | fixed |
+| SEC-18 | low | Unvalidated argument names and unknown tool names reach the audit log | fixed |
+| SEC-19 | low | One fixed cookie name for concurrent sign-ins in the same browser | fixed |
+
+All 19 findings were fixed or waived in S2 (status column and per-finding status lines below); the
+negative tests live in `tests/security/`. The fixes found four further defects that are fixed in
+the same changeset: secrets inside JSON object keys were not pattern masked (`fef80a5`), a
+trailing newline passed the `sudo` pattern (`984673e`), a `data` field on an Action secret
+response was not redacted (`421a650`), and configuration errors for `OAUTH_SCOPES` and
+`TOOLSETS` echoed the offending values (`0f5f5cd`).
+
+No critical findings. Verified as sound (no finding): static bearer comparison, the identity
+split between static bearer, OAuth and no-auth (including OAuth-only deployments), Sudo
+handling for OAuth users, path, query and header encoding in the executor, redirect handling,
+response size and JSON depth bounds, stdio stdout hygiene, error detail exposure, PKCE, code
+and refresh replay handling, consent CSRF and clickjacking headers, the browser-binding
+cookie, token store encryption and atomic writes, the setup command's env file handling, and
+the Dockerfile (pinned digests, non-root, no secrets in layers).
+
+## Findings
+
+### SEC-01 (high): unbounded request body on the unauthenticated consent POST
+
+- Status: fixed in `d5ca530`: consent and callback routes wrapped in a 16 KiB body limit; 415 for any content type but `application/x-www-form-urlencoded` before a byte is read; form parsed with `max_files=0, max_fields=8, max_part_size=4096`. Tests: `tests/security/test_oauth_input_bounds.py`.
+- Where: `src/aegis_gitea_mcp/oauth/callback.py:137-155` (`consent_submit` calls
+  `await request.form()`), routes at `callback.py:169-173`.
+- Description: the browser routes are custom Starlette routes. Unlike the MCP endpoint and the
+  SDK's `/authorize`, `/token`, `/register` and `/revoke` (all wrapped in
+  `RequestBodyLimitMiddleware`), they have no body limit, and `uvicorn` sets none. Starlette
+  parses `multipart/form-data` with up to 1000 fields of up to 1 MiB each held in memory, and
+  file parts of unlimited size spooled to `/tmp`, which is a RAM-backed tmpfs in the shipped
+  `docker-compose.yml`. The `Origin` check passes when the header is absent, and the CSRF check
+  only runs after parsing. Reproduced: one unauthenticated POST with 500 one-megabyte multipart
+  fields raised the server's RSS from 93 MB to 593 MB; a single 200 MB file part was consumed
+  completely before the 400 answer. The per-IP limit (120 requests per minute) counts requests,
+  not bytes, so a single client can exhaust memory and get the process killed. OAuth mode only.
+- Fix: wrap the consent and callback routes in `RequestBodyLimitMiddleware` with a small cap
+  (16 KiB is ample: the form has three short fields); answer 415 before reading the body when
+  the content type is not `application/x-www-form-urlencoded`; parse with
+  `request.form(max_files=0, max_fields=8, max_part_size=4096)`.
+- Negative test (`tests/security/test_oauth_input_bounds.py`): drive the ASGI app with a
+  counting `receive`; a 1 MiB urlencoded POST to `/oauth/consent` gets 413 having read at most
+  the cap plus one chunk; a multipart POST gets 415 having read no body; a valid consent still
+  works.
+
+### SEC-02 (medium): stored webhook `authorization_header` returned by hook read tools
+
+- Status: fixed in `5b622e6`: `SENSITIVE_RESPONSE_KEYS` (the request-side key list) redacts non-empty string values by key name at any depth in every result except credential-issuing operations, in all `SECRET_DETECTION_MODE` values. Tests: `tests/security/test_secret_echo.py`.
+- Where: `src/aegis_gitea_mcp/gitea/executor.py:339-356` and `603-625` (only values submitted
+  in the request body are redacted, via `sensitive_body_values` in
+  `src/aegis_gitea_mcp/gitea/encoding.py:387-405`).
+- Description: the Gitea `Hook` schema includes `authorization_header`, and Gitea fills it on
+  list, get and edit. A create call redacts the header because the caller submitted it, but
+  `gitea_hook_repo_list_hooks`, `gitea_hook_repo_get_hook` and the org, user and admin
+  equivalents (and `gitea_api_request` on hook paths) return stored headers verbatim to the
+  model and the remote client. Reproduced with a mocked `repoListHooks` answer: the header
+  value appears in the result. Pattern masking does not catch `Basic ...` or most `Bearer ...`
+  values.
+- Fix: redact known secret-bearing response fields in `_seal`, before pattern masking: a
+  non-empty `authorization_header` at any depth becomes `[REDACTED]` (presence stays visible).
+  Keep the set (`_SENSITIVE_RESPONSE_KEYS`) next to `_SENSITIVE_BODY_KEYS` so new fields are
+  added in one place. Credential-issuing operations are unaffected (no hook operation is one).
+- Negative test (`tests/security/test_secret_echo.py`): list, get and edit hook responses
+  (repo, org, user, admin, and the raw tool on `/repos/o/r/hooks`) containing
+  `authorization_header` never contain the value in `content` or `structured_content`, with
+  `SECRET_DETECTION_MODE` set to `off`, `mask` and `block`.
+
+### SEC-03 (medium): audit write failures after startup do not stop later calls
+
+- Status: fixed in `43eebd3`: the write-ahead alternative: a `tool_call_started` entry is written before every known tool runs and the call is refused with `audit_unavailable` when it fails. Documented in `docs/audit-logging.md`. Tests: `tests/security/test_audit_fail_closed.py`.
+- Where: `src/aegis_gitea_mcp/server.py:414-426` (only obtaining the logger is checked) and
+  `server.py:509-537` (write errors are logged and swallowed);
+  `src/aegis_gitea_mcp/audit.py:104-107`.
+- Description: the fail-closed check only proves the file could be opened once. Once the
+  singleton exists, a full disk, a revoked mount or any other write error makes every later call
+  run unaudited, indefinitely, while AGENTS.md promises an audit event for every call. The
+  post-execution swallow is intentional for the call that already ran, but nothing stops the
+  next one.
+- Fix: record audit health. On a write failure set `AuditLogger.healthy = False`; at the start
+  of `call_tool`, refuse with `audit_unavailable` while unhealthy, after one probe write
+  (a small `audit_probe` security event) fails. Alternatively write a `tool_invocation_started`
+  entry before execution and refuse when it fails. Either way, document the choice in
+  `docs/audit-logging.md`.
+- Negative test (`tests/security/test_audit_fail_closed.py`): after one successful call, make
+  the log file's `write` raise `OSError`; the next call returns `audit_unavailable` and the
+  mocked Gitea receives no request; when writes work again, calls resume.
+
+### SEC-04 (medium): settings read a `.env` file from the process working directory
+
+- Status: fixed in `79aa4f7`: `./.env` loads only as a regular file owned by the user with mode 0600; `--env-file` and `AEGIS_ENV_FILE`; documented in README, configuration and troubleshooting. Tests: `tests/security/test_env_file.py`.
+- Where: `src/aegis_gitea_mcp/config.py:109-114` (`env_file=".env"`).
+- Description: pydantic-settings loads `./.env` for every setting not present in the
+  environment. Claude Code and other clients start stdio servers with the project directory as
+  the working directory, so a cloned repository can plant a `.env`. Reproduced: with
+  `GITEA_URL` and `GITEA_TOKEN` in the environment, a world-readable `.env` in the working
+  directory set `SECRET_DETECTION_MODE=off`, `EXPOSE_ERROR_DETAILS=true` and
+  `AUDIT_LOG_PATH=/dev/null` (all calls then go unaudited, and the startup audit check passes).
+  A client configuration without `GITEA_URL` in the environment would also send the token to an
+  attacker-chosen `GITEA_URL`.
+- Fix: honour `./.env` only when it is a regular file (not a symlink) owned by the current user
+  and not readable or writable by group or others (the mode `setup` writes, 0600); otherwise
+  ignore it and print one warning to stderr. Add an explicit `--env-file` option (and
+  `AEGIS_ENV_FILE`) for other locations. Document it in `docs/configuration.md`.
+- Negative test (`tests/security/test_env_file.py`): a 0644 `.env` in the working directory
+  with `SECRET_DETECTION_MODE=off` and `AUDIT_LOG_PATH=/dev/null` is ignored (mode stays
+  `mask`, the audit path stays under `DATA_DIR`); a symlinked `.env` is ignored; a 0600 `.env`
+  owned by the user is honoured; environment values still win.
+
+### SEC-05 (medium): any https redirect URI can be registered; the consent page is the only barrier
+
+- Status: fixed, default waived (W-10) in `8be8592`: owner decision: optional `OAUTH_REDIRECT_ALLOWLIST` (exact URIs or `https://host/` prefixes, checked at registration and `/authorize`); the open default is waived with the consent page as mitigation, and the allowlist is recommended for public deployments. Tests: `tests/security/test_oauth_redirects.py`.
+- Where: `src/aegis_gitea_mcp/oauth/provider.py:99-115` (`redirect_uri_problem`),
+  `provider.py:306-343` (`register_client`), `src/aegis_gitea_mcp/oauth/callback.py:109-135`.
+- Description: dynamic client registration is open to anyone and accepts any https redirect
+  URI and any `client_name`. Gitea remembers consent for our single application, so the only
+  thing between a phishing link and a victim's full-scope token (default `write:` on every
+  category, including admin for site admins) is a click on our consent page, which shows an
+  attacker-chosen name (for example "Claude") and the redirect URI. The design is documented in
+  ADR 0004; this is an owner decision on residual risk.
+- Fix (owner to choose): add `OAUTH_REDIRECT_HOSTS`, an allowlist of redirect hosts accepted at
+  registration (default: loopback plus the hosted clients the owner uses, for example
+  `claude.ai` and `chat.mistral.ai`), with a clear registration error otherwise; on the consent
+  page show the redirect host first and prominently and the client's registration age. Or accept
+  the risk and record it as a waiver in `docs/security.md`.
+- Negative test (`tests/security/test_oauth_redirects.py`): with the allowlist set,
+  registering `https://evil.example/cb` returns `invalid_redirect_uri`; allowlisted and loopback
+  URIs register; existing rules (http on non-loopback, fragments, credentials, custom schemes)
+  stay rejected.
+
+### SEC-06 (medium): fork pull requests run Docker-capable jobs on the shared runner
+
+- Status: fixed in `766968f`: `test-integration`, `test-mcp` and `build-and-push` carry the fork guard. The Gitea setting "require approval for workflows from forks" is a manual step recorded in `docs/deployment.md`. Tests: `tests/security/test_ci_workflows.py`.
+- Where: `.gitea/workflows/ci.yml:22-25` (`pull_request` to `dev` and `main`), jobs
+  `test-integration` (`ci.yml:119-144`) and `test-mcp` (`ci.yml:153-185`).
+- Description: a pull request from a fork runs its own workflow and test code, and these jobs
+  use the runner's Docker daemon (building images, starting containers, joining networks).
+  Access to the daemon is root-equivalent on the host that other tenants share. Secrets are not
+  passed to fork runs, but the host is.
+- Fix: enable "require approval for workflows from forks" (or the equivalent runner setting) in
+  Gitea, and guard the Docker jobs with
+  `if: github.event_name == 'push' || github.event.pull_request.head.repo.full_name == github.repository`.
+  Record the setting in `docs/deployment.md` or the CI notes.
+- Negative test (`tests/security/test_ci_workflows.py`): parse the workflow YAML; every job that
+  calls `docker` (or the integration and MCP smoke jobs by name) carries the fork guard.
+
+### SEC-07 (medium): CI actions pinned by mutable tags, one of them receives the registry token
+
+- Status: fixed in `766968f`: every `uses:` is pinned to a full commit SHA with a version comment; `docker/login-action` was replaced by `docker login --password-stdin` into a per-job `DOCKER_CONFIG`; `persist-credentials: false` on every checkout. Tests: `tests/security/test_ci_workflows.py`.
+- Where: `.gitea/workflows/ci.yml:40, 63-69, 90-108, 124-130, 160-166, 206, 242, 299-305,
+  324-330`; `.gitea/workflows/publish.yml:22-28, 47-53, 77-85, 138`. `docker/login-action@v3`
+  receives `REGISTRY_TOKEN` (`ci.yml:242-248`).
+- Description: `actions/checkout@v4`, `actions/setup-python@v5`, `astral-sh/setup-uv@v5`,
+  `actions/upload-artifact@v4` and `docker/login-action@v3` resolve to whatever the tag points to
+  at run time. A compromised or retagged action runs with the job's secrets and the Docker
+  daemon. `actions/checkout` also persists the job token in `.git/config` for later steps.
+- Fix: pin every `uses:` to a full commit SHA with the version in a comment; replace
+  `docker/login-action` with `echo "$REGISTRY_TOKEN" | docker login --username ... --password-stdin`;
+  set `persist-credentials: false` on checkout where pushing is not needed.
+- Negative test (`tests/security/test_ci_workflows.py`): every `uses:` value in
+  `.gitea/workflows/*.yml` matches `@[0-9a-f]{40}$`; no step passes `secrets.*` to a third-party
+  action's `with:`.
+
+### SEC-08 (low): rate limiting gaps
+
+- Status: fixed in `f57c237`: `/token` and `/revoke` rate limited; IPv6 clients keyed by /64; `ForwardedHeadersMiddleware` applies forwarded headers for `FORWARDED_ALLOW_IPS` peers and logs one warning for any other peer that sends `X-Forwarded-For`. Tests: `tests/security/test_rate_limits.py`.
+- Where: `src/aegis_gitea_mcp/oauth/components.py:37` (`RATE_LIMITED_PATHS` lacks `/token` and
+  `/revoke`), `src/aegis_gitea_mcp/rate_limit.py:142-163` (per-IP key is the full address),
+  `src/aegis_gitea_mcp/transports.py:168-188`, `transports.py:400-419`.
+- Description: `/token` and `/revoke` (client secret checks, store writes) are not limited. Each
+  IPv6 address is its own bucket, so a client with a /64 is effectively unlimited. Behind a
+  proxy whose address is not in `FORWARDED_ALLOW_IPS` (the default `127.0.0.1` does not match a
+  Docker network), every request shares the proxy's bucket, and because the limit runs before
+  authentication, any unauthenticated client can exhaust the budget of all authenticated users.
+- Fix: add `/token` and `/revoke` to `RATE_LIMITED_PATHS`; key IPv6 clients by their /64; log a
+  one-time warning when a request carries `X-Forwarded-For` from a peer outside
+  `FORWARDED_ALLOW_IPS`.
+- Negative test (`tests/security/test_rate_limits.py`): limit+1 requests to `/token` get 429;
+  two addresses in one IPv6 /64 share a bucket; a forwarded header from an untrusted peer logs
+  the warning once.
+
+### SEC-09 (low): OAuth pre-sign-in state can be flushed by unauthenticated floods
+
+- Status: fixed in `87f048c`: per client address at most 20 pending sign-ins and 20 registrations per hour; clients younger than `PENDING_TTL` are never evicted; the store write runs in a worker thread. Tests: `tests/security/test_oauth_input_bounds.py`.
+- Where: `src/aegis_gitea_mcp/oauth/provider.py:139-159` (`_ExpiringMap.put` evicts the oldest
+  entry), `provider.py:80-85`, `provider.py:333-356` (client eviction),
+  `src/aegis_gitea_mcp/oauth/store.py:250-275` (synchronous fsync on the event loop).
+- Description: 1024 `/authorize` requests (needs only a self-registered client) evict every
+  legitimate pending sign-in; 500 registrations evict recently registered clients that have
+  not finished signing in. Every registration writes and fsyncs the whole store on the event
+  loop. Impact: sign-in denial of service, no data exposure.
+- Fix: per-IP quota on pending requests and registrations (for example 20 each); never evict a
+  client younger than `PENDING_TTL`; run `OAuthStore._write` in a worker thread
+  (`anyio.to_thread.run_sync`).
+- Negative test (`tests/security/test_oauth_input_bounds.py`): 1100 `/authorize` calls from one
+  IP do not evict a pending request from another IP; a client registered a minute ago survives
+  a registration flood.
+
+### SEC-10 (low): base URLs accept whitespace and control characters; plain http Gitea is silent
+
+- Status: fixed in `d96c3ac`: whitespace, backslash and control characters rejected in both URLs, the URL is rebuilt from its parsed parts, `serve` warns for plain http to a non-loopback Gitea (a warning rather than a refusal, so existing lab setups keep working). Tests: `tests/security/test_base_url_validation.py`.
+- Where: `src/aegis_gitea_mcp/config.py:87-103` (`_normalize_http_url` validates the parsed URL
+  but returns the raw string), `config.py:180-201`.
+- Description: `https://gi\ttea.example.com`, `https://gitea.example.com/a\nb` and values with
+  spaces pass validation; `urlsplit` strips tabs and newlines for the check while the raw value
+  is used later, so the validated and the used URL can differ. A plain `http://` `GITEA_URL` to a
+  non-loopback host is accepted at serve time without any warning, although the admin token, the
+  OAuth client secret and user tokens then travel in clear text (setup warns, `serve` does not).
+- Fix: reject any whitespace or non-printable character in both URLs; return the URL rebuilt
+  from its parsed parts; print a startup warning (or refuse unless an explicit
+  `ALLOW_INSECURE_GITEA_URL=true`) for http to a non-loopback host.
+- Negative test (`tests/security/test_base_url_validation.py`): parametrized rejection of tab,
+  newline, carriage return, space, NUL and bidi controls in `GITEA_URL` and `PUBLIC_BASE_URL`;
+  existing rejections (scheme, credentials, query, fragment, bad port, missing host, http public
+  base URL) kept; `serve` with `GITEA_URL=http://gitea.internal` prints the warning.
+
+### SEC-11 (low): audit log created with umask defaults; unkeyed hash chain
+
+- Status: fixed, keyed chain waived (W-11) in `7307214`: directory 0700, log opened `O_NOFOLLOW` with mode 0600, an older loose log is tightened, startup exits 2 for a symlink. The optional `AUDIT_HMAC_KEY` was not added: off-host shipping is the documented integrity control. Tests: `tests/security/test_audit_file.py`.
+- Where: `src/aegis_gitea_mcp/audit.py:36-39`, `audit.py:64-69`.
+- Description: `DATA_DIR` is created with the default mode (0755 under a 022 umask) and the
+  audit log with 0644; only the OAuth store later tightens the directory, so in admin-token mode
+  other local users can read logins, paths and timing of every call. The audit path is opened
+  without `O_NOFOLLOW`. The SHA-256 chain has no key, so anyone with write access can rewrite
+  it consistently, and truncating the tail is not detectable.
+- Fix: create the directory with 0700 and open the log with
+  `os.open(path, O_WRONLY | O_APPEND | O_CREAT | O_NOFOLLOW, 0o600)`; document off-host
+  shipping as the integrity control, optionally add an `AUDIT_HMAC_KEY` for a keyed chain.
+- Negative test (`tests/security/test_audit_file.py`): after the first call the log is 0600 and a
+  newly created `DATA_DIR` is 0700; a symlink at the audit path makes startup exit 2.
+
+### SEC-12 (low): tool audit entries do not record the client, session or source IP
+
+- Status: fixed in `fd5e4b7`: tool entries carry `client_id`, a 12 character `session` hash and `client_ip`. Tests: `tests/security/test_audit_fail_closed.py`.
+- Where: `src/aegis_gitea_mcp/server.py:509-537`.
+- Description: in OAuth mode an entry names the Gitea login but not which MCP client or grant
+  made the call, nor the source address, which limits incident response (for example finding
+  which registered client a stolen token belonged to).
+- Fix: add `client_id` from the verified access token, a short hash of the session id and the
+  client IP (when on HTTP) to the tool invocation entry.
+- Negative test (`tests/security/test_audit_fail_closed.py` or a sibling): an OAuth call's entry
+  contains the client id and no token or session id in clear.
+
+### SEC-13 (low): token store directory ownership is not verified
+
+- Status: fixed in `6f7a3c0`: the store directory must be owned by the effective user and must not stay group or world writable; checked on load and on every save. Tests: `tests/security/test_token_store.py`.
+- Where: `src/aegis_gitea_mcp/oauth/store.py:133-143`.
+- Description: an existing `DATA_DIR` owned by another user, or one that stays group or world
+  writable after the chmod attempt, only produces a warning. Whoever controls the directory can
+  replace the store with an older copy (resurrecting revoked grants) or delete it.
+- Fix: refuse (raise `OAuthStoreError`) when the directory's owner is not the effective user or
+  it is still writable by group or others.
+- Negative test (`tests/security/test_token_store.py`): with a directory reported as owned by
+  another uid (monkeypatched `os.stat`) or mode 0777 that cannot be tightened, loading or saving
+  fails with a clear message.
+
+### SEC-14 (low): CI cleanup and credential handling on the shared Docker daemon
+
+- Status: fixed in `766968f`: cleanup removes containers only for per-run refs (`aegis-ci-*`, `:sha-*`) and only untags shared tags; the credential directory is per job; `uv publish` reads `UV_PUBLISH_PASSWORD`. Tests: `tests/security/test_ci_workflows.py` (fake `docker` on `PATH`).
+- Where: `scripts/ci/cleanup_job_resources.sh:43-48`, `.gitea/workflows/ci.yml:281-290`,
+  `.gitea/workflows/publish.yml:150-157`.
+- Description: the cleanup removes every container whose `ancestor` is one of the given refs,
+  and the build job passes the shared tags `:latest`, `:main` and `:dev`; on a daemon that also
+  runs a deployment of this image that can remove containers that are not the job's.
+  `docker logout` acts on the shared credential store when the job is not containerized.
+  `uv publish --password "${REGISTRY_TOKEN}"` puts the token on the command line.
+- Fix: remove containers only for per-run refs (`aegis-ci-<run id>-*` and the job's own
+  `:sha-` tag); for shared tags only untag (`docker image rm` of the tag); pass the publish
+  token through `UV_PUBLISH_PASSWORD`.
+- Negative test (`tests/security/test_ci_workflows.py`): run the cleanup script with a fake
+  `docker` on `PATH` that records argv; `rm -f` is only issued for containers of per-run refs;
+  `publish.yml` contains no `--password` argument.
+
+### SEC-15 (low): `tests/security` missing; publish not gated on the security job
+
+- Status: fixed in `766968f`: `tests/security` exists (this suite) and `publish.yml` has a `security` job that `publish` needs (gitleaks, security tests, pip-audit, ruff `S`). Tests: `tests/security/test_ci_workflows.py`.
+- Where: `.gitea/workflows/ci.yml:337`, `.gitea/workflows/publish.yml` (needs only lint and
+  test).
+- Description: `pytest tests/security` exits with code 4 (path not found), so the CI `security`
+  job fails today. The publish workflow ships packages without gitleaks, pip-audit or the
+  security tests.
+- Fix: S2 creates the suite listed below; add a `security` job (pip-audit, ruff `S`, security
+  tests, gitleaks) to `publish.yml` and make `publish` need it.
+- Negative test: the suite itself; a CI workflow test asserting `publish` needs the security
+  job.
+
+### SEC-16 (low): no container image vulnerability scan
+
+- Status: fixed in `766968f`: Trivy 0.76.0 pinned with sha256 (`scripts/ci/install_trivy.sh`) scans the built image in `build-and-push` before the push and fails on fixable HIGH or CRITICAL findings (`scripts/ci/scan_image.sh`, waivers in `security/trivyignore.txt`); `scan.yml` repeats it weekly as the digest refresh reminder. Verified locally against the built image (clean).
+- Where: `docker/Dockerfile:6-7`, `.gitea/workflows/ci.yml` (`build-and-push`).
+- Description: base image digests are pinned and refreshed by hand; OS package advisories in
+  the image are never checked.
+- Fix: add a scan step (Trivy or Grype pinned by digest) on the built image, failing on high and
+  critical with a waiver file, and a scheduled digest refresh reminder.
+- Negative test: CI only (the step runs and fails on a known vulnerable test image).
+
+### SEC-17 (low): consent POST accepts a missing `Origin` header
+
+- Status: fixed in `782d416`: consent POST needs an `Origin` equal to the public origin, with the `Referer` origin as fallback; missing, `null` or foreign values are refused. Tests: `tests/security/test_oauth_csrf.py`.
+- Where: `src/aegis_gitea_mcp/oauth/callback.py:138-140`; ADR 0004 says approval needs "a
+  matching `Origin`".
+- Description: the `SameSite=Strict` double-submit cookie is the effective CSRF control and is
+  sound, but the code and the ADR disagree. Browsers send `Origin` on form POSTs.
+- Fix: require `Origin` to equal the public origin (fall back to `Referer` when `Origin` is
+  absent), or correct the ADR.
+- Negative test (`tests/security/test_oauth_csrf.py`): POST without `Origin` and `Referer`,
+  with `Origin: null`, and with a foreign origin all get 400 and no redirect.
+
+### SEC-18 (low): unvalidated argument names and unknown tool names reach the audit log
+
+- Status: fixed in `fd5e4b7`: only argument names that are schema properties are recorded (rest counted as `rejected_argument_count`); unknown tool names are recorded as `(unknown tool, N chars)` and not echoed. Tests: `tests/security/test_audit_fail_closed.py`.
+- Where: `src/aegis_gitea_mcp/server.py:412-413` (argument names recorded before validation),
+  `server.py:428-431` (unknown tool name echoed and audited).
+- Description: validation messages carefully avoid caller-chosen argument names because "they
+  could carry a secret", but the audit entry records them before validation, and an unknown tool
+  name (up to 128 characters) is written to the audit log and echoed in the error. Pattern
+  masking still runs, so only non-pattern secrets are affected.
+- Fix: record only argument names that are properties of the tool's schema (plus a count of
+  rejected ones); record unknown tool names as a fixed marker plus length, and do not echo them.
+- Negative test (`tests/security/test_redaction.py`): a call with an extra argument named like a
+  40-hex token, and a call to a tool named like one, leave neither value in the audit file or
+  the error.
+
+### SEC-19 (low): one fixed cookie name for concurrent sign-ins in the same browser
+
+- Status: fixed in `782d416`: the binding cookie is named per flow (`aegis-oauth-flow-<8 hex of the state hash>`). Tests: `tests/security/test_oauth_csrf.py`.
+- Where: `src/aegis_gitea_mcp/oauth/callback.py:56-60`, `callback.py:150-155`.
+- Description: a second sign-in started in the same browser overwrites the first flow's binding
+  cookie. The first callback then fails and writes a high-severity
+  `oauth_callback_binding_mismatch` audit event, a false alarm that trains operators to ignore
+  the one event that signals a confused-deputy attempt.
+- Fix: suffix the binding cookie name with a short hash of the Gitea `state`
+  (`__Host-aegis-oauth-flow-<8 hex>`), and look it up by the state on the callback.
+- Negative test (`tests/security/test_oauth_csrf.py`): two interleaved flows in one browser
+  both complete; a callback without its own cookie still fails and is audited.
+
+## Negative tests S2 added to `tests/security/`
+
+All of the files below exist now (the list is kept as the specification they were written
+from). Results are in the "Verification results" section of [security.md](security.md).
+
+Some of these duplicate existing unit tests on purpose: the security suite is the one CI and
+reviewers read, and it must stay green independently of refactors elsewhere. Reuse the helpers
+in `tests/test_oauth_helpers.py` and `tests/test_executor_helpers.py`.
+
+1. `test_auth_required.py`
+   - `/mcp` without `Authorization` gets 401 with `WWW-Authenticate` (bearer-only app and OAuth
+     app).
+   - Wrong bearer gets 401: same length, shorter, longer, empty, wrong scheme (`Basic`, `token`),
+     trailing whitespace, the bearer of another deployment.
+   - The static bearer is compared with `hmac.compare_digest` on digests (spy).
+   - OAuth: expired, revoked, other-resource and unknown `agm_` tokens get 401; an `agm_` token
+     never resolves to the admin identity (Gitea mock sees the user's token only).
+   - Route inventory: the set of routes reachable without authentication is exactly
+     `/`, `/health`, the `.well-known` documents and the OAuth routes; adding a route fails the
+     test.
+2. `test_startup_fail_closed.py`
+   - Non-loopback binds (`0.0.0.0`, `::`, a public IP, a host name, `127.1`, `0`) without bearer
+     or OAuth exit 2 and never call `uvicorn.run`.
+   - Half-configured OAuth, a bearer shorter than 32 characters, an http `PUBLIC_BASE_URL` on a
+     public host, an unwritable audit log and (SEC-11) a symlinked audit path all exit 2.
+3. `test_redaction.py`
+   - With all secrets configured (`GITEA_TOKEN`, `MCP_BEARER_TOKEN`, `GITEA_OAUTH_CLIENT_SECRET`,
+     `TOKEN_ENCRYPTION_KEY`, a user's Gitea access and refresh tokens, an issued `agm_` token),
+     drive a Gitea error that echoes each of them and a success body that contains each of them:
+     none appears in the result, the error message, the audit file, or captured logs at DEBUG.
+   - `uvicorn.access` records for `/oauth/callback?code=...&state=...` and
+     `/oauth/consent?request=...` contain `[redacted]` instead of the query.
+   - `repr` of `Settings`, `Identity`, `SessionRecord`, `UpstreamTokens` and
+     `PendingAuthorization` contains no secret.
+   - Validation errors never contain argument values (SEC-18 for names).
+4. `test_secret_echo.py`
+   - `gitea_actions_repo_list_secrets` and `gitea_actions_org_list_secrets` return the names
+     Gitea sends; the update tools never echo the submitted `data`, including in a Gitea 422
+     error that repeats it.
+   - SEC-02: hook list, get and edit responses never contain `authorization_header` values, in
+     every `SECRET_DETECTION_MODE`.
+   - Submitted `password`, `secret`, `token`, `authorization_header` and migration credentials
+     are redacted from results.
+   - Credential-issuing operations return the new credential (documented exemption, W-07) but
+     the audit file and logs do not contain it.
+5. `test_malformed_input.py`
+   - Unknown arguments, wrong types, missing required arguments rejected before Gitea is
+     contacted.
+   - Path values with `..`, `.`, empty segment, `\`, `?`, `#`, `%`, `%2e`, NUL, CR, LF, U+2028
+     rejected for catalog path parameters and for the raw tool path; a raw path starting `//`
+     rejected.
+   - Query names `token`, `access_token`, `sudo`, `_sudo` in any case rejected.
+   - `sudo` with CR/LF, spaces or over 255 characters rejected.
+   - Upload: oversized base64 rejected before decoding, invalid base64, filenames with quotes or
+     CR/LF, unknown file keys.
+   - Raw method outside the enum; `READ_ONLY` with a non-GET raw call.
+   - Deeply nested JSON arguments and bodies give an error result, never an exception.
+   - HTTP: body over the cap gets 413, non-JSON content type 400, foreign `Host` 421, foreign
+     `Origin` 403.
+6. `test_base_url_validation.py`
+   - `GITEA_URL` and `PUBLIC_BASE_URL`: non-http schemes, credentials, query, fragment, bad port,
+     missing host, whitespace and control characters (SEC-10), http public base URL on a public
+     host; trailing `/api/v1` normalized.
+   - `MCP_PATH`, `FORWARDED_ALLOW_IPS` and `OAUTH_SCOPES` (unknown scope) rejections.
+   - Redirect URIs at registration: http on non-loopback, fragment, credentials, `javascript:`,
+     custom schemes rejected.
+7. `test_oauth_csrf.py` (SEC-17, SEC-19): consent without the CSRF cookie, with a mismatched
+   token, without or with a foreign `Origin`; callback without the binding cookie, with a
+   replayed or expired state; none of them redirects.
+8. `test_oauth_input_bounds.py` (SEC-01, SEC-09).
+9. `test_audit_fail_closed.py` and `test_audit_file.py` (SEC-03, SEC-11, SEC-12).
+10. `test_env_file.py` (SEC-04).
+11. `test_token_store.py`: file mode 0600, directory 0700, symlink refused, wrong key stops
+    startup without wiping, store content is not plaintext, our tokens only as hashes, SEC-13.
+12. `test_rate_limits.py` (SEC-08).
+13. `test_ci_workflows.py` (SEC-06, SEC-07, SEC-14, SEC-15).
+
+## B5 checker verdict
+
+Verdict: CHANGES REQUIRED (at `ce5ae6c`; the blocking item was fixed in S2, `d5ca530`, and
+every non-blocking item below was fixed or waived, see the status column above).
+
+Blocking:
+
+- SEC-01: the unauthenticated consent POST reads unbounded multipart bodies into memory and
+  tmpfs. This is B5 code and reproducible with one request. Fix and its negative test are
+  required before B5 is accepted.
+
+Non-blocking (fix in S2, or record as waivers): SEC-05 (redirect allowlist, owner decision),
+SEC-09, SEC-12, SEC-13, SEC-17 (code or ADR), SEC-19.
+
+What was checked and holds:
+
+- Identity separation: an access token with the OAuth marker always resolves to its own
+  session or fails; it never falls back to the admin token, even when the session ends or the
+  upstream refresh fails. Only the static bearer (or no token on stdio and unauthenticated
+  loopback) reaches admin-token mode; an OAuth-only deployment fails closed for it. The session
+  login is checked against the token subject.
+- Authorization server: DCR client ids are minted by the SDK; PKCE S256 is mandatory towards
+  clients and used towards Gitea; redirect URIs are validated at registration and matched by the
+  SDK; codes are single use, bound to the client, replay revokes the grant; refresh tokens rotate
+  and reuse revokes the grant; revocation is limited to the owning client by the SDK; tokens are
+  bound to the MCP resource and scope.
+- Browser flow: consent CSRF double submit with a `SameSite=Strict` `__Host-` cookie, a
+  browser-binding cookie on the callback, single-use states, no redirect on any invalid callback,
+  `no-store`, `no-referrer`, `DENY` framing and CSP on every page, HTML escaping of the client
+  name and redirect URI, no request parameter echoed.
+- Upstream: confidential client with form-encoded credentials, no redirects followed, coarse
+  error kinds only, login validated against a strict pattern, token type and length checked,
+  unknown Gitea scopes rejected at configuration.
+- Store: Fernet with an HKDF-SHA256 key, mode 0600 through `O_EXCL` temporary files and atomic
+  rename, symlinks refused, a wrong key or corrupt file stops startup without wiping, our tokens
+  stored only as hashes, pruning of expired tokens and abandoned sessions, bounded clients and
+  sessions per login.
+- Secret handling: the user's refresh token, the store key and the client secret are redacted
+  from results; issued `agm_` tokens are masked by pattern; access-log query strings are dropped.
+- Quality gates at `ce5ae6c`: 157 OAuth tests and the whole unit suite pass (846 passed, 23
+  skipped), coverage 98.2 percent, `ruff check`, `ruff format --check` and `mypy` clean. The docs
+  drift check failed only on the stale `docs/security.md`, replaced in this changeset.

 # Security
 
-## Core Controls
+AegisGitea-MCP is a full-access bridge into Gitea (ADR 0001): whoever can call it holds the
+power of the Gitea token it uses, which for the admin token means the whole instance. The
+server does not decide which operations are safe. It guarantees a small set of invariants
+(authentication off loopback, identity separation, audit, secret redaction, bounded and
+validated input and output, untrusted-content labelling) and leaves exposure to the owner
+(`READ_ONLY`, `TOOLSETS`, `DISABLED_TOOLS`, token scopes). The operator checklist is
+[hardening.md](hardening.md); open review findings are in
+[security-findings.md](security-findings.md) (all 19 findings of the S2 review are fixed or
+waived).
 
-- OAuth2/OIDC bearer-token authentication for MCP tool execution.
-- OIDC discovery + JWKS validation cache for JWT tokens.
-- Userinfo validation fallback for opaque OAuth tokens.
-- Scope enforcement:
-  - `read:repository` for read tools.
-  - `write:repository` for write tools.
-- Policy engine checks before tool execution.
-- Per-IP and per-token rate limiting.
-- Strict schema validation (`extra=forbid`).
-- Tamper-evident audit logging with hash chaining.
-- Secret sanitization for logs and tool output.
-- Production-safe error responses (no internal stack traces).
+## Threat model
 
-## Threat Model
+### Assets
 
-### Why shared bot tokens are dangerous
+| Asset | Where it lives | Impact if lost |
+|---|---|---|
+| Admin Gitea token (`GITEA_TOKEN`) | env file or container env; process memory | Full control of the instance, including Sudo as any user |
+| MCP bearer (`MCP_BEARER_TOKEN`) | env file; remote clients' configuration | Equivalent to the admin token over HTTP |
+| OAuth client secret (`GITEA_OAUTH_CLIENT_SECRET`) | env file | Impersonating this server towards Gitea's OAuth endpoints |
+| Per-user Gitea access and refresh tokens | `DATA_DIR/oauth-store.json` (encrypted), process memory | Acting as each signed-in user, for as long as Gitea accepts the refresh token |
+| Our issued `agm_` access and refresh tokens | clients; only SHA-256 hashes in the store | Acting as one user through this server until expiry or revocation |
+| Token store and its key (`TOKEN_ENCRYPTION_KEY`) | store in `DATA_DIR`, key in env | Store plus key discloses every user's Gitea tokens and every client secret |
+| Action secret values, webhook auth headers, minted credentials | in transit through tool calls | Credentials of CI, webhooks and other systems |
+| Audit log (`DATA_DIR/audit.log`) | `DATA_DIR` | Loss of accountability; integrity is the asset, not secrecy |
 
-- A single leaked bot token can expose all repositories that bot can access.
-- Access is not naturally bounded per end user.
-- Blast radius is large and cross-tenant.
+### Actors
 
-### Why token-in-URL is insecure
+- Owner: configures the server, holds the admin token. Trusted.
+- OAuth users: Gitea accounts that sign in through a client. Trusted with their own Gitea
+  permissions only.
+- Remote MCP clients, including hosted ones (claude.ai, Mistral Le Chat): hold a bearer or an
+  OAuth token and act through a model that reads untrusted content.
+- Malicious Gitea content authors: anyone who can write an issue, comment, file, commit
+  message, release note or wiki page the model may read.
+- Network attackers: anyone who can reach the HTTP port or sit on the path to it or to Gitea.
+- Other tenants of the shared CI host: jobs and services on the same runner and Docker daemon.
 
-- URLs can be captured by reverse proxy logs, browser history, referer headers, and monitoring pipelines.
-- Bearer tokens must be passed in `Authorization` headers only.
+### Trust boundaries
 
-### Why per-user OAuth reduces lateral access
+1. MCP client to HTTP endpoint (`transports.py`): unauthenticated network input until a bearer
+   or `agm_` token is verified (`auth.py`, `oauth/provider.py`).
+2. Browser to OAuth routes (`oauth/callback.py`, SDK `/authorize`, `/token`, `/register`,
+   `/revoke`): unauthenticated, cross-site capable.
+3. Verified token to identity (`oauth/resolver.py`, `auth.py`): decides which Gitea token a
+   call uses.
+4. Server to Gitea (`gitea/executor.py`, `oauth/upstream.py`): Gitea is trusted for
+   authorization decisions, its content is not trusted.
+5. Tool result to model: everything Gitea returns crosses into a model context.
+6. Process to disk (`audit.py`, `oauth/store.py`, `config.py` reading `.env`).
+7. Repository to CI runner (`.gitea/workflows/*.yml`, `scripts/ci/*`): code under test runs
+   with access to the runner's Docker daemon.
 
-- Each MCP request executes with the signed-in user token.
-- Gitea authorization stays source-of-truth for repository visibility.
-- A compromised token is limited to that user�s permissions.
+### Threats and mitigations
 
-## Resource-type-aware authorization
+Spoofing
 
-The public server runs in *service-PAT mode*: a privileged bot token makes the
-actual Gitea calls while the per-user OAuth identity decides what the user may
-reach. Repository calls are gated by the user's collaborator permission on
-`owner/repo`. The rest of the Gitea surface — reachable through the
-`gitea_request` escape hatch — is gated by **resource-type-aware authorization**
-(`authz.py`). Every call is classified by `(method, path)` and enforced against
-a type-specific rule. **Every decision fails closed**: a call that cannot be
-classified, or whose permission cannot be positively verified against Gitea, is
-denied and audited.
+| Threat | Mitigation | Implemented in |
+|---|---|---|
+| Calling the endpoint without credentials | Non-loopback bind refuses to start without a bearer or OAuth; SDK `RequireAuthMiddleware` answers 401 | `transports.py` (`http_startup_errors`, `build_http_app`) |
+| Guessing the bearer | 32 character minimum; constant-time comparison of SHA-256 digests; per-IP and per-token rate limit before auth | `config.py`, `auth.py` (`StaticBearerVerifier`), `rate_limit.py` |
+| Using a token minted for another resource | RFC 8707 resource binding and required scope `gitea` enforced by the SDK; `/authorize` with a foreign `resource` gets `invalid_target` | `transports.py` (`_auth_settings`), `oauth/provider.py` |
+| Confused deputy through the shared Gitea OAuth app | Own consent page naming client and redirect URI, CSRF double submit with `SameSite=Strict` cookie, browser-binding cookie on the callback | `oauth/callback.py`, `oauth/provider.py` (residual: W-10, optional `OAUTH_REDIRECT_ALLOWLIST`) |
+| Code or refresh token replay | Single-use codes; replay or reuse of a rotated refresh token revokes the grant | `oauth/provider.py` |
 
-| Resource type | Rule (service-PAT mode) |
-|---------------|--------------------------|
-| `repository` | Per-user collaborator permission on `owner/repo` (existing check). A repo path that cannot be parsed to `owner/repo` is denied. |
-| `org` | The signed-in user must be a **verified member** of the target org (checked against Gitea, fail closed). |
-| `user_owned` | A resource owned by a named user/org (`/users/{name}`, `/packages/{owner}`): allowed only when the owner is the caller, or the caller is a verified member of the owning org. |
-| `user_self` | Token-owner-scoped endpoints (`/user`, `/notifications`): **denied** — in service-PAT mode the data belongs to the bot, not the caller. |
-| `misc_global` | Instance-wide read-only utilities (markdown render, version, gitignore templates): reads allowed; writes denied. |
-| `admin` | **Default deny.** Allowed only when the operator opts in (`RAW_API_ALLOW_SENSITIVE=true`) **and** the signed-in user is a verified Gitea site administrator. |
-| `unknown` | Denied. |
+Tampering
 
-This gate runs *in addition to* the policy engine and the `WRITE_MODE` gate — a
-write call is denied unless write mode is on, policy allows it, and the
-resource-type rule passes. In pure-OAuth mode (no service PAT) the user's own
-token already scopes every call at Gitea, so the extra gate is unnecessary.
+| Threat | Mitigation | Implemented in |
+|---|---|---|
+| Path traversal or path reshaping into other Gitea routes | Path values rejected on `..`, `.`, empty segment, `\`, `?`, `#`, `%`, control characters; percent-encoded with `safe=""` except verified wildcard routes | `gitea/encoding.py` |
+| Header injection (Sudo, multipart) | Sudo restricted to `[A-Za-z0-9_.-]{1,255}`; filenames and content types single line, no quotes; header parameters of the spec never forwarded | `gitea/encoding.py`, `catalog/build.py` |
+| Query smuggling of credentials or Sudo | `token`, `access_token`, `sudo`, `_sudo` refused as query names (any case) | `gitea/encoding.py` |
+| Malformed arguments | JSON Schema validation (Draft 2020-12, `additionalProperties: false`) before anything runs; messages never echo values | `server.py` |
+| Store tampering or wrong key | Fernet (authenticated encryption) with an HKDF-SHA256 key; undecryptable store stops startup instead of being wiped; symlinks refused | `oauth/store.py` (the directory must be owned by the running user and not group or world writable) |
+| Settings injection from a planted `.env` | `./.env` is loaded only when it is a regular file, not a symlink, owned by the user, mode 0600; otherwise ignored with a warning; `--env-file` or `AEGIS_ENV_FILE` name a file explicitly; the environment wins | `config.py` (`select_env_file`), `cli.py` |
 
-Positive verification results (org membership, site-admin) are cached briefly
-and bounded; only successful checks are cached, so a transient failure never
-grants access.
+Repudiation
 
-## Full-API coverage: classified `gitea_request`
+| Threat | Mitigation | Implemented in |
+|---|---|---|
+| Unrecorded tool calls | Exactly one hash-chained result entry per call, preceded by a write-ahead `tool_call_started` entry; a call is refused when either the logger or that write fails; startup fails on an unwritable log | `server.py`, `audit.py`, `transports.py` |
+| Undetected edits of the log | SHA-256 hash chain, `scripts/validate_audit_log.py` | `audit.py` (unkeyed chain: waiver W-11) |
 
-`gitea_request` exposes the long tail of the Gitea API that the curated typed
-tools do not cover, safely:
+Information disclosure
 
-- **Deterministic read/write classifier.** `GET`/`HEAD` are reads; everything
-  else is a write. A small, explicit override table may only *downgrade*
-  provably side-effect-free render endpoints (markdown/markup) to reads — never
-  the reverse — so a mutating call can never be misclassified as a read and slip
-  past the `WRITE_MODE` gate.
-- **Known-path gate.** A request whose top path segment is not a recognized
-  Gitea `/api/v1` route prefix is denied (fail closed): unknown paths are never
-  passed straight through.
-- **Admin/credential denylist.** `/admin`, `*tokens*`, `*secrets*`, `*hooks*`,
-  `*keys*`, `applications/oauth2`, and runner registration tokens are blocked for
-  every method (including `GET`) and cannot be re-opened from `policy.yaml` —
-  only `RAW_API_ALLOW_SENSITIVE=true` overrides them, and admin then still
-  requires a verified site administrator (see above).
+| Threat | Mitigation | Implemented in |
+|---|---|---|
+| Tokens in results or errors | Exact redaction of the identity token, refresh token, admin token, bearer, client secret, store key and submitted secret fields in every result and error; pattern masking per `SECRET_DETECTION_MODE` | `gitea/executor.py`, `gitea/redaction.py`, `security.py` |
+| Tokens in logs | JSON log formatter without tracebacks; query strings dropped from access logs; upstream errors reduced to coarse kinds | `logging_utils.py`, `transports.py` (`AccessLogQueryFilter`), `oauth/upstream.py` |
+| Secret values echoed back | Submitted `password`, `secret`, `token` style fields and Action secret `data` redacted from the result; secret-bearing response fields (stored webhook `authorization_header`, `secret`, `password` and the rest of `SENSITIVE_RESPONSE_KEYS`, and `data` on Action secret operations) redacted by key name; secrets in object keys masked | `gitea/encoding.py` (`sensitive_body_values`, `SENSITIVE_RESPONSE_KEYS`), `gitea/executor.py` |
+| Leaks across identities | No cookie jar, no redirects followed, a fresh upstream client per OAuth exchange | `gitea/executor.py`, `oauth/upstream.py` |
+| Stack traces | `EXPOSE_ERROR_DETAILS=false` by default; even when on, only the exception class name | `server.py`, `gitea/executor.py` |
 
-## Prompt Injection Hardening
+Denial of service
 
-Repository content is treated as untrusted data.
+| Threat | Mitigation | Implemented in |
+|---|---|---|
+| Large request bodies | SDK body limit on the MCP endpoint and SDK OAuth routes; upload cap checked before decoding | `server.py` (`max_request_body_size`), `gitea/encoding.py`, `oauth/callback.py` (16 KiB cap, form content type only) |
+| Large or hostile responses | 16 MiB text cap, `MAX_BINARY_BYTES`, 64 KiB error bodies, JSON depth 100, item and character limits | `gitea/executor.py` |
+| Request floods | Sliding window per IP and per token hash, bounded key sets, rate-limit events audited once per window | `rate_limit.py`, `transports.py` (`ForwardedHeadersMiddleware`) |
+| Unbounded OAuth state | Caps on clients (500), pending sign-ins (1024), codes (1024), sessions per login (50); per client address at most 20 pending sign-ins and 20 registrations per hour; clients younger than the pending window are never evicted; store pruning; the store write (fsync) runs in a worker thread | `oauth/provider.py`, `oauth/store.py` |
 
-- Tool outputs are bounded and sanitized.
-- No instructions from repository text are executed.
-- Text fields are size-limited before returning to LLM clients.
+Elevation of privilege
 
-## Secret Detection
+| Threat | Mitigation | Implemented in |
+|---|---|---|
+| OAuth user reaching the admin token | Tokens with the OAuth marker only ever resolve to their session; only the static bearer (or no token on stdio and unauthenticated loopback) reaches admin-token mode; OAuth-only deployments fail closed | `oauth/resolver.py`, `auth.py` |
+| OAuth user using Sudo | Sudo is sent with the caller's own token; Gitea honours it only for site admins | `gitea/executor.py` |
+| Unknown Gitea scopes granting full access | Only granular `read:`/`write:` scopes accepted for `OAUTH_SCOPES` | `config.py` |
+| Model tricked by injected content | Untrusted-content labelling and annotations (see below); exposure narrowed by configuration | `server.py`, `gitea/executor.py` |
+| Untrusted code on the shared CI host | Per-run resource names and targeted cleanup | `.gitea/workflows/ci.yml`, `scripts/ci/cleanup_job_resources.sh`; fork pull requests do not run the Docker jobs |
 
-Detected classes include:
+### Residual risks and owner decisions
 
-- API key and token patterns.
-- JWT-like tokens.
-- Private key block markers.
-- Common provider credential formats.
+- Full access by default (ADR 0001). A leaked bearer equals the admin token. Sudo, admin,
+  secrets and delete tools are enabled unless the owner narrows them.
+- Unauthenticated loopback mode is allowed for development. Any local user or process on the
+  same host then acts with the admin token. Set a bearer on shared hosts.
+- Hosted clients (claude.ai, Le Chat) hold the bearer or an OAuth refresh token outside the
+  owner's control. Prefer per-user OAuth and narrow `OAUTH_SCOPES`; the default grants
+  `write:` on every category, including admin for site admins.
+- Credential-issuing operations (`gitea_user_create_token`, runner registration tokens such as
+  `gitea_admin_create_runner_registration_token`, OAuth2 application secrets,
+  `gitea_repo_create_deploy_token`) return the new credential to the model by design; only the
+  caller's own tokens are still redacted.
+- Secret pattern masking is heuristic. Content containing third-party credentials (for example a
+  Gitea token committed to a file) is returned unless it matches a pattern.
+- SSRF through Gitea features (migrations, webhooks, mirrors) is Gitea's responsibility; this
+  server only ever contacts `GITEA_URL`.
+- With the default `OAUTH_REDIRECT_ALLOWLIST` (empty), the consent page is the only barrier
+  against phishing with a self-registered client (waiver W-10). For a public deployment set the
+  allowlist to the hosted clients you use, for example
+  `OAUTH_REDIRECT_ALLOWLIST=https://claude.ai/,https://chat.mistral.ai/`.
+- Key rotation for `TOKEN_ENCRYPTION_KEY` is not supported: a new key means moving the store
+  away and signing every user out.
+- The audit chain is tamper-evident, not tamper-proof: anyone with write access to the file can
+  rewrite it consistently. Ship it off the host.
 
-Behavior:
+## Prompt injection
 
-- `SECRET_DETECTION_MODE=mask`: redact in place.
-- `SECRET_DETECTION_MODE=block`: replace secret-bearing values.
-- `SECRET_DETECTION_MODE=off`: disable sanitization (not recommended).
+Everything returned from Gitea is untrusted data. Every success envelope carries the fixed
+`untrusted_content` notice, the server instructions tell the model never to follow
+instructions found in Gitea content, and the server itself never interprets content (it does
+not follow links, render, execute or chain calls). Tool annotations mark read-only and
+destructive operations so clients can require confirmation. The realistic attack is a model
+that reads a hostile issue and then calls a destructive tool; the defences are client-side
+confirmation, `READ_ONLY`, `TOOLSETS`, `DISABLED_TOOLS` and narrow token scopes
+([hardening.md](hardening.md)).
+
+## Secret hygiene guarantees
+
+- Settings hold secrets as `SecretStr`; `Identity`, `SessionRecord`, `UpstreamTokens` and the
+  pending authorization exclude tokens from `repr`.
+- Results and errors: exact redaction of every known secret (identity token and refresh token,
+  `GITEA_TOKEN`, `MCP_BEARER_TOKEN`, `GITEA_OAUTH_CLIENT_SECRET`, `TOKEN_ENCRYPTION_KEY`,
+  secret fields submitted in the request), then pattern masking or blocking.
+- Validation errors and argument errors never contain argument values.
+- Audit entries carry argument names, never values, and are masked again before writing.
+- Logs: JSON lines, exception type only, access-log query strings replaced by `[redacted]`.
+- Our own tokens are stored only as SHA-256 hashes; the store file is encrypted, mode 0600,
+  written through `O_EXCL` temporary files and an atomic rename.
+- Action secrets: Gitea's list endpoints (`gitea_actions_repo_list_secrets`,
+  `gitea_actions_org_list_secrets`) return names and descriptions only (a `data` field in an
+  Action secret response is redacted should Gitea ever send one), and a submitted value
+  (`gitea_actions_update_repo_secret` and siblings) is redacted from the result at any length.
+- A webhook's stored `authorization_header` (and any other field in `SENSITIVE_RESPONSE_KEYS`)
+  is redacted by key name in every result, whatever `SECRET_DETECTION_MODE` says; an empty
+  value stays visible as empty. Credential-issuing operations are the only exemption (W-07).
+- With `SECRET_DETECTION_MODE=off` pattern matching is disabled, which also removes the only
+  protection of our own issued `agm_` tokens and of the MCP client secrets (only hashes of the
+  tokens exist on the server, so they cannot be redacted exactly). Exact redaction of every
+  other known secret stays on in all modes.
+- Configuration errors name the setting and the rule and never the value (including unknown
+  `OAUTH_SCOPES` and `TOOLSETS` entries).
+
+## Transport guarantees
+
+- Fail-closed bind: `MCP_HOST` defaults to `127.0.0.1`; any non-loopback bind without a bearer
+  or a working OAuth setup exits with code 2. A half-configured OAuth setup also exits 2.
+- Constant-time bearer check on SHA-256 digests, so neither content nor length leaks.
+- DNS-rebinding protection on the MCP endpoint: `Host` must be a loopback name, the bind
+  address, the `PUBLIC_BASE_URL` host or an `ALLOWED_HOSTS` entry (421 otherwise); a foreign
+  `Origin` gets 403; POST must be `application/json`.
+- Rate limits: sliding window per client IP (IPv6 per /64) and per Authorization hash on the
+  MCP path and the unauthenticated OAuth paths (`/register`, `/authorize`, `/token`, `/revoke`,
+  consent, callback), before authentication. Client IPs come from `X-Forwarded-For` only for
+  `FORWARDED_ALLOW_IPS`; a forwarded header from any other peer is ignored and logged once.
+- `PUBLIC_BASE_URL` must be https unless loopback. `GITEA_URL` and `PUBLIC_BASE_URL` reject
+  whitespace, backslashes and control characters and are rebuilt from their parsed parts;
+  plain http `GITEA_URL` to a non-loopback host prints a startup warning. Gitea redirects are
+  never followed.
+- stdio: stdout carries JSON-RPC only; all logging goes to stderr.
+
+### Per-user OAuth design
+
+The server is an OAuth 2.1 authorization server for MCP clients (SDK provider, dynamic client
+registration, PKCE S256 required) and a confidential PKCE client of Gitea. Flow: `/authorize`
+parks the request and shows our consent page (client name, redirect URI, warning). Approval
+needs the form CSRF token, the matching `SameSite=Strict` cookie and a request `Origin` equal
+to the public origin (the `Referer` origin when `Origin` is absent; neither, or `null`, is
+refused). It sets a browser-binding cookie named per flow (`aegis-oauth-flow-<8 hex of the
+state hash>`, `__Host-` prefixed and `Secure` on https, `HttpOnly`), so concurrent sign-ins in
+one browser do not overwrite each other. The Gitea
+callback is completed only in the browser holding that cookie; unknown, expired or replayed
+states never redirect. Pages send `Cache-Control: no-store`, `Referrer-Policy: no-referrer`,
+`X-Frame-Options: DENY` and a CSP with `frame-ancestors 'none'`. Redirect URIs must be https,
+or http on loopback, without credentials or fragments. Issued tokens are opaque (`agm_` plus 256
+random bits), hashed at rest, bound to the MCP resource; access tokens live 1 hour, refresh
+tokens 30 days with rotation. Revocation ends the whole grant.
+
+## Supply chain
+
+- Base images pinned by digest (`python:3.12-slim`, `ghcr.io/astral-sh/uv`), non-root runtime
+  user, root-owned virtualenv, no build arguments carrying secrets, `.dockerignore` excludes
+  `.env`.
+- Dependencies locked in `uv.lock` and installed with `uv sync --locked`.
+- `pip-audit` over the exported lock (`scripts/ci/pip_audit.sh`, waivers in
+  `security/pip-audit-ignore.txt`).
+- gitleaks pinned to 8.30.1 with sha256 verification, full-history scan with
+  `.gitleaks.toml`.
+- ruff `S` (bandit) rules enabled in the normal lint and run separately in the `security` job.
+- Every third-party action in `.gitea/workflows/*.yml` is pinned to a full commit SHA with the
+  version in a comment; no secret is passed to a third-party action (the registry login uses the
+  Docker CLI with the token on stdin in a per-job `DOCKER_CONFIG`, `uv publish` reads
+  `UV_PUBLISH_PASSWORD`); checkout does not persist the job token.
+- Docker and secret jobs do not run for pull requests from forks.
+- The image built in `build-and-push` is scanned with a pinned Trivy (0.76.0, sha256 verified)
+  before it is pushed; fixable HIGH and CRITICAL findings fail the job (waivers in
+  `security/trivyignore.txt`). `scan.yml` repeats the image scan and the dependency audit weekly.
+- `publish.yml` needs the same `security` gates (gitleaks, security tests, pip-audit, ruff `S`).

+| Dependency audit | `bash scripts/ci/pip_audit.sh` (pip-audit 2.10.1, `--strict`) | No known vulnerabilities in 83 locked packages (runtime and dev groups). No ignores in use. |
+| Bandit rules | `uv run ruff check --select S .` (ruff 0.17.0) | All checks passed, with the inline waivers listed below. |
+| Secret scan | `scripts/ci/install_gitleaks.sh` into a scratch directory, then `gitleaks git --config .gitleaks.toml --redact --no-banner --verbose --exit-code 1 .` (gitleaks 8.30.1) | No leaks found, 137 commits scanned (about 6.4 MB). |
+| Image scan | `scripts/ci/install_trivy.sh`, then `scripts/ci/scan_image.sh <image built from docker/Dockerfile>` (Trivy 0.76.0, HIGH and CRITICAL, fixable only) | Clean: no findings in the Debian 13 base or the Python packages. |

+
+## Waivers
+
+Accepted findings, each with its reason. A new waiver needs a reason here in the same
+changeset.
+
+| Id | Finding | Where | Reason |
+|---|---|---|---|
+| W-01 | S104 (bind to all interfaces) | `transports.py` `_WILDCARD_HOSTS`, `tests/test_server_helpers.py`, `tests/test_config.py` | The addresses are compared or used as test input, never bound. The container binds 0.0.0.0 through `MCP_HOST`, which requires authentication. |
+| W-02 | S105/S106 (hardcoded password) | `auth.py` (`token="static"`), `oauth/provider.py` (`TOKEN_PREFIX`, `token_type="Bearer"`), `audit.py` (mode string), `setup_snippets.py` (`TOKEN_PLACEHOLDER`) | Placeholders, public prefixes and type names, not secrets. |
+| W-03 | S101 (assert) | `setup_cmd.py` (two narrowing asserts) | Type narrowing after an explicit check; behaviour does not depend on the assert. |
+| W-04 | S101, S105, S106, S108 in `tests/**`; S603, S607 in `tests/integration/harness.py` and `tests/mcp/helpers.py` | `pyproject.toml` per-file ignores, inline noqa | Test fixtures use fake tokens and temporary paths; the harness drives the trusted local Docker CLI with fixed argv. |
+| W-05 | gitleaks allowlists | `.gitleaks.toml` | Only `generic-api-key` and `curl-auth-header`, only in `tests/`, `docs/`, removed legacy guides and one removed source file; every match was reviewed as a fake or placeholder. |
+| W-06 | pip-audit | `security/pip-audit-ignore.txt` | Empty: no advisory is ignored. |
+| W-07 | Credential-issuing operations bypass pattern masking | `gitea/executor.py` (`CREDENTIAL_ISSUING_OPERATIONS`) | Their purpose is to return a new credential; exact redaction of the caller's own tokens still applies. |
+| W-08 | Unauthenticated `/health` and `/` report version and tool count, `/health` reports Gitea reachability | `transports.py` | Needed by container health checks and clients; reveals no configuration or secret. The Gitea probe is cached for 10 seconds. |
+| W-09 | Pattern masking keeps the first and last 4 characters of a matched secret | `security.py` (`mask_secret`) | Applies only to pattern matches, which are at least 16 characters; the remainder keeps enough entropy, and the context helps users recognise the value. |
+| W-10 | Any https redirect URI can be registered when `OAUTH_REDIRECT_ALLOWLIST` is empty (SEC-05) | `oauth/provider.py` (`redirect_uri_problem`), `config.py` | Owner decision: the default stays open so any MCP client can register without configuration. The mitigation is the consent page (client name, redirect host and URI, explicit approval, CSRF and browser binding) and ADR 0004. The optional allowlist closes the gap: exact URIs or `https://host/` prefixes, checked at registration and at `/authorize`; recommended for every public deployment. |
+| W-11 | Audit chain is unkeyed (SEC-11) | `audit.py` | The chain is tamper-evident, not tamper-proof, and an `AUDIT_HMAC_KEY` kept next to the log would not change that for an attacker with host access. The integrity control is shipping the log off the host and comparing the latest `entry_hash` (see audit-logging.md). The directory is 0700 and the file 0600, and symlinks are refused. |

+# Tool inventory
+
+This file is generated. Do not edit it by hand: run `uv run python scripts/check_docs.py --write` after changing the catalog. CI fails when it is out of date.
+
+There are 538 tools: 537 generated from the pinned Gitea 28.1.0 swagger (`spec/gitea-swagger.v1.json`, one tool per operation) plus the hand-written `gitea_api_request`, which is listed under misc.
+
+Naming: `gitea_<domain>_<action>`, lowercase snake_case, at most 64 characters. The domain comes from the request path, the action from the swagger operationId. Names are stable for a given spec version.
+
+Every tool also accepts an optional `sudo` argument (a Gitea login). With an admin token the call then runs as that user. Paths are relative to `/api/v1`.
+
+Filters: `TOOLSETS` limits the exposed domains, `READ_ONLY` exposes only read-only operations (`gitea_api_request` then accepts only GET), `DISABLED_TOOLS` hides single tools by name. A filtered tool is neither listed nor callable. See [configuration.md](configuration.md).
+
+Flags: read-only (maps to the MCP `readOnlyHint`), destructive (`destructiveHint`: deletes and calls that replace state), paginated (accepts `page` and `limit`), file upload (takes base64 file content), admin (needs a site-admin token).

 # Troubleshooting
 
-## "Internal server error (-32603)" from Claude
+Start with the result of the failing call: errors carry `error.status`, `error.kind` and
+Gitea's sanitized message, and the audit log has a result entry (`tool_invocation`) per call, preceded by a `tool_call_started` entry (see
+[audit-logging.md](audit-logging.md)).
 
-**Symptom:** Claude shows `Internal server error` with JSON-RPC error code `-32603` when trying to use Gitea tools.
+## The server does not start
 
-**Cause:** In user-token mode, the OAuth token stored by the client may have been issued without Gitea API scopes (e.g. `read:repository`). In service-PAT mode, the call may fail because the authenticated user does not have the required repository permission or the permission probe cannot be completed.
+| Message or exit | Cause and fix |
+|---|---|
+| Exit code 2, "GITEA_TOKEN" required (stdio) | stdio needs `GITEA_TOKEN`. Put it in the client's `env` block, or in an env file passed with `--env-file` (or `AEGIS_ENV_FILE`). A `.env` in the working directory counts only when it is a regular file you own with mode 0600. |
+| Warning "ignoring ./.env: ..." | The working directory's `.env` is a symlink, owned by someone else or accessible to group or others, so its settings are not loaded. Run `chmod 600 .env`, or pass `--env-file PATH`. See "Which env file is read" in [configuration.md](configuration.md). |
+| Exit code 2, "env file ... does not exist" | The file named by `--env-file` or `AEGIS_ENV_FILE` is missing or not a regular file. |
+| Exit code 2, refuses a non-loopback bind | `MCP_HOST` is not loopback and there is no `MCP_BEARER_TOKEN` or complete OAuth setup. Set one of them, or bind `127.0.0.1` behind a reverse proxy. |
+| Exit code 2, lists OAuth settings | `OAUTH_ENABLED=true` needs `GITEA_OAUTH_CLIENT_ID`, `GITEA_OAUTH_CLIENT_SECRET`, `TOKEN_ENCRYPTION_KEY` and `PUBLIC_BASE_URL`. |
+| Exit code 2, "cannot decrypt .../oauth-store.json" | `TOKEN_ENCRYPTION_KEY` differs from the key the store was written with (or the file is damaged). The server does not wipe it. Restore the original key, or move `DATA_DIR/oauth-store.json` away to start over (signs every OAuth user out). |
+| Exit code 2, "owned by another user" or "writable by group or others" (OAuth) | `DATA_DIR` must belong to the user the server runs as and not be group or world writable. Fix the owner or `chmod 700`. |
+| Validation error naming a setting | See the rules in [configuration.md](configuration.md): URLs must be http(s) without credentials, `PUBLIC_BASE_URL` must be https, secrets need 32 characters, `OAUTH_SCOPES` accepts only granular scopes. |
+| Startup error listing tool names | `DISABLED_TOOLS` contains names that are not registered. Check [tools.md](tools.md). |
 
-**Fix:**
-1. In Gitea: Go to **Settings > Applications > Authorized OAuth2 Applications** and revoke the MCP application.
-2. In Claude: disconnect the MCP server and authenticate again.
-3. Re-authorize: Use the MCP connector again. It will trigger a fresh OAuth flow. For repository-targeted calls in service-PAT mode, also verify the signed-in Gitea user has read/write access to the target repository.
+## stdio client shows nothing or breaks
 
-**Verification:** Check the server logs for `oauth_auth_summary`. A working token shows:
-```
-oauth_auth_summary: api_probe=pass login=alice
-```
-A scopeless token shows:
-```
-oauth_token_lacks_api_scope: status=403 login=alice
-```
+stdout carries only JSON-RPC. If a wrapper script prints to stdout before the server starts, the
+client fails to parse the stream. Logs go to stderr; look at the client's MCP server log.
+`uvx` needs access to the package index that hosts `aegis-gitea-mcp`: pass
+`--index https://git.hiddenden.cafe/api/packages/Hiddenden/pypi/simple/`, see
+[packaging.md](packaging.md). If you register the server with `claude mcp add`, put `--env`
+before `--transport stdio` and the server name, as `setup` prints it.
 
-## "Gitea rejected the API call" (403)
+## Tool calls fail
 
-**Symptom:** Tool calls return 403 with a message about re-authorizing.
+| `kind` | Meaning |
+|---|---|
+| `unauthorized` (401) | Gitea rejected the token: wrong, expired or revoked. In OAuth mode the user signs in again. |
+| `forbidden` (403) | The token or the user lacks the scope or permission. Admin tools return this for non-admins. Widen the token scopes (see "Token scopes" in the [README](../README.md)) or change the user's rights in Gitea. Sudo needs a site-admin token. |
+| `not_found` (404) | The object does not exist, or Gitea hides it from this identity. Also returned for endpoints the Gitea version lacks. |
+| `validation_failed` (422), `bad_request` (400) | Gitea rejected the values. The message says which. |
+| `invalid_argument` | The arguments do not match the tool schema (missing, wrong type, extra property, bad owner or repository name). The message gives the path, not the value. |
+| `timeout`, `upstream_unreachable` | Gitea did not answer within `REQUEST_TIMEOUT_SECONDS`, or the connection failed. Check `GITEA_URL` from the server's host (DNS, TLS, firewall). |
+| `redirect` | Gitea answered with a redirect, which is never followed. Use the final URL (for example https) as `GITEA_URL`. |
+| `payload_too_large` | The response is above `MAX_BINARY_BYTES`. Raise it or fetch a smaller object. |
+| `secret_blocked` | `SECRET_DETECTION_MODE=block` withheld a result containing secret-like content. Use `mask` if that is acceptable. |
+| `audit_unavailable` | The audit log could not be opened, so the call was refused before it reached Gitea. Fix the permissions of `AUDIT_LOG_PATH` (or `DATA_DIR`) and restart. |
+| `rate_limited` (429) | Gitea or this server's `RATE_LIMIT_PER_MINUTE` limit. |
 
-**Cause:** The OAuth token does not have the required API scope in user-token mode, or the per-user repository permission check denied the request in service-PAT mode.
+A result with a `truncated` object was cut to `MAX_TOOL_RESPONSE_ITEMS` or
+`MAX_TOOL_RESPONSE_CHARS`. Use `page` and `limit` on paginated tools to walk through it.
 
-**Fix:** Revoke and re-authorize if the token lacks API scope. If the error mentions repository permission, grant the signed-in Gitea user the required repository access or use a repository they can access.
+A tool the client cannot see is probably filtered by `TOOLSETS`, `READ_ONLY` or
+`DISABLED_TOOLS`. Calling a filtered or unknown tool is a protocol error.
 
-## Claude caches stale tokens
+## HTTP problems
 
-**Symptom:** After fixing the OAuth configuration, Claude still sends the old token.
+- `GET /health` returns 503 `degraded`: the server cannot reach Gitea (the probe is cached for
+  10 seconds). Fix connectivity from the server's host.
+- 401 on `/mcp`: no or wrong bearer token, and no valid OAuth token. The response has a
+  `WWW-Authenticate` header that points clients to the OAuth metadata.
+- Request rejected with an invalid Host (421): the name you used is not allowed. Add it to
+  `ALLOWED_HOSTS` or set `PUBLIC_BASE_URL`. With a non-loopback `MCP_HOST` and neither variable
+  the server prints a warning at startup that says so.
+- 429: the client exceeded `RATE_LIMIT_PER_MINUTE`. If every client seems to share one limit,
+  the proxy address is not in `FORWARDED_ALLOW_IPS`, so all requests look like they come from
+  the proxy.
+- The server exits with code 2 and "cannot open the audit log": the audit file or its directory
+  is not writable. Fix the permissions, or point `AUDIT_LOG_PATH` or `DATA_DIR` at a writable
+  location (in Docker, check the volume ownership). The server never runs without an audit log.
+- Responses arrive in one chunk or time out behind nginx: set `proxy_buffering off;`.
 
-**Cause:** The client caches access tokens and doesn't automatically re-authenticate when the server configuration changes.
+## OAuth sign-in
 
-**Fix:**
-1. Disconnect the server in the client.
-2. Start a new conversation and use the integration again - this forces a fresh OAuth flow.
-
-## How OAuth scopes work with Gitea
-
-Gitea's OAuth2/OIDC implementation uses **granular scopes** for API access:
-
-| Scope | Access |
-|-------|--------|
-| `read:repository` | Read repositories, issues, PRs, files |
-| `write:repository` | Create/edit issues, PRs, comments, files |
-| `openid` | OIDC identity (login, email) |
-
-When an OAuth application requests authorization, the `scope` parameter in the authorize URL determines what permissions the resulting token has. If only OIDC scopes are requested (e.g. `openid profile email`), the token can establish identity but may not be usable for direct Gitea REST calls. When `GITEA_TOKEN` is configured, the server uses OIDC for identity and checks the user's repository permission before using the service PAT.
-
-The MCP server's OAuth metadata controls which scopes the client requests. Ensure it includes:
-```yaml
-scopes:
-  read:repository: "Read access to Gitea repositories"
-  write:repository: "Write access to Gitea repositories"
-```
-
-## Reading the `oauth_auth_summary` log
-
-Every authenticated request emits a structured log line:
-
-| Field | Description |
-|-------|-------------|
-| `token_type` | `jwt` or `opaque` |
-| `scopes_observed` | Scopes extracted from the token/userinfo |
-| `scopes_effective` | Final scopes after implicit grants |
-| `api_probe` | `pass`, `fail:403`, `fail:401`, `skip:cached`, `skip:error` |
-| `login` | Gitea username |
-
-- `api_probe=pass` — token works for Gitea API calls
-- `api_probe=fail:403` — token lacks API scopes, request rejected with re-auth guidance
-- `api_probe=skip:cached` — previous probe passed, cached result used
-- `api_probe=skip:error` — network error during probe, request allowed to proceed
-- `repository_permission_denied` in the audit log — the user lacks required read/write permission for a service-PAT call
+- The client reports that dynamic client registration is unsupported: OAuth is off. Set
+  `OAUTH_ENABLED=true` and the settings that go with it.
+- Gitea shows a redirect URI error: the OAuth application's redirect URI must be exactly
+  `<PUBLIC_BASE_URL>/oauth/callback`. Re-run `setup --public-base-url ...` or fix it in Gitea.
+- Signed in, but admin tools return 403: the user is not a site administrator. That is intended.
+- Users are asked to sign in again after a restart: the `DATA_DIR` volume changed or was not
+  persistent (a changed `TOKEN_ENCRYPTION_KEY` stops startup instead, see above). Keep the key
+  stable and the volume persistent.
+- The sign-in page says the request is invalid or expired: the consent page lives 10 minutes
+  and a form is single use. Start the sign-in again from the client. Registration or sign-in
+  refused with "too many": one client address may hold 20 pending sign-ins and register 20
+  clients per hour.
+- After fixing OAuth settings the client still fails: some clients cache tokens. Disconnect the
+  server in the client and connect again, which starts a fresh flow. Users can also revoke the
+  application under Settings, Applications, Authorized OAuth2 Applications in Gitea.

-# Write Mode
-
-## Threat Model
-
-Write mode introduces mutation risk (issue/PR changes, metadata updates). Risks include unauthorized action, accidental mass updates, and audit evasion.
-
-## Default Posture
-
-- `WRITE_MODE=false` by default.
-- When enabled, writes require repository whitelist membership by default.
-- Optional opt-in: `WRITE_ALLOW_ALL_TOKEN_REPOS=true` allows writes to any repo the token can access.
-- Policy engine remains authoritative and may deny specific write tools.
-
-## Supported Write Tools
-
-- `create_issue` (optional `milestone` id or title)
-- `update_issue` (optional `milestone`; `0` clears it)
-- `create_issue_comment`
-- `create_pr_comment`
-- `edit_issue_comment`
-- `add_labels`
-- `remove_labels`
-- `assign_issue`
-- `create_label`
-- `update_label`
-- `create_pull_request`
-- `create_release`
-- `edit_release`
-- `create_branch`
-- `create_milestone`
-
-Not supported (explicitly forbidden): merge actions, branch/label/release deletion,
-force push, repo/admin management, and repository content writes (file create/edit,
-commits). Gitea Projects (Kanban boards) are unsupported because the Gitea REST API
-exposes no project endpoints.
-
-## Enablement Steps
-
-1. Set `WRITE_MODE=true`.
-2. Choose one:
-   - `WRITE_REPOSITORY_WHITELIST=owner/repo,...` (recommended)
-   - `WRITE_ALLOW_ALL_TOKEN_REPOS=true` (broader scope)
-3. Review policy file for write-tool scope.
-4. Verify audit logging and alerting before rollout.
-
-## Safe Operations
-
-- Start with one repository in whitelist.
-- Use narrowly scoped bot credentials.
-- Require peer review for whitelist/policy changes.
-- Disable write mode during incident response if abuse is suspected.
-
-## Risk Tradeoffs
-
-Write mode improves automation and triage speed but increases blast radius. Use least privilege, tight policy, and strong monitoring.

+"""OAuth 2.1 authorization server for MCP clients, proxying sign-in to Gitea.
+
+Implements the SDK's ``OAuthAuthorizationServerProvider``. The SDK mounts
+``/authorize``, ``/token``, ``/register``, ``/revoke`` and the metadata, and
+does PKCE, redirect URI matching and client authentication; this module holds
+the state behind them.
+
+Sign-in flow (each step single use, every value 256-bit random):
+
+1. ``/authorize`` (SDK) calls :meth:`GiteaOAuthProvider.authorize`, which parks
+   the client's request under a random request id and sends the browser to our
+   consent page.
+2. The consent page (``callback.py``) shows which client asks for access and
+   where the result goes. Approving needs a CSRF token that is bound to the
+   browser by a ``SameSite=Strict`` cookie. On approval a fresh Gitea ``state``
+   and a browser-binding secret are created; the binding secret goes into a
+   cookie and the browser is sent to Gitea with our own PKCE challenge.
+3. ``/oauth/callback`` pops the state, checks the binding cookie (so a Gitea
+   redirect URL obtained by someone else cannot be completed in a victim's
+   browser), exchanges Gitea's code, looks up the user and mints our
+   authorization code for the client's registered redirect URI.
+4. ``/token`` (SDK, PKCE checked) calls :meth:`exchange_authorization_code`,
+   which issues opaque ``agm_`` access and refresh tokens. Only their SHA-256
+   hashes are stored.
+
+The consent step exists because Gitea remembers consent for our (single,
+static) Gitea application: without it, anyone could register a client with
+their own redirect URI and turn a victim's click on a link into a token for
+the victim's account (the confused-deputy problem of OAuth proxies).

+"""Encrypted on-disk store for OAuth clients, sessions and token hashes.
+
+One file, ``DATA_DIR/oauth-store.json``, holds the whole state as a single
+Fernet-encrypted JSON document. The Fernet key is derived from
+``TOKEN_ENCRYPTION_KEY`` with HKDF-SHA256, so the setting can be any long random
+string (the setup command writes a ``secrets.token_urlsafe`` value, not a Fernet
+key).
+
+What is stored:
+
+* registered MCP clients, including their client secrets (the SDK compares the
+  presented secret with the stored one at ``/token``);
+* sessions: the Gitea login and the user's Gitea access and refresh tokens;
+* our own access and refresh tokens, only as SHA-256 hashes.
+
+File safety: the directory is created with mode 0700 (an existing one must be owned by the
+running user and is tightened to 0700, otherwise startup stops) and the file is written
+with mode 0600 through a fresh ``O_EXCL`` temporary file and an atomic
+``os.replace``. A symlink at the store path is refused. A file that cannot be
+decrypted or parsed stops startup with a clear message instead of being wiped,
+because wiping would silently sign every user out and hide a wrong key.
+
+Mutations happen synchronously in memory (so a check-and-delete is atomic under
+asyncio) and are persisted with :meth:`OAuthStore.save`.

+## The suite
+
+Tests call tools through the MCP server (an in-memory `Client` on `build_server`, run as
+the admin of the throwaway instance), so schema validation, the result envelope, the audit
+log and the executor are all exercised. State lives in `tmp_path`.
+
+- `test_scenario_*.py`: happy paths with real state changes (org and team, repository
+  files, branches and tags, issues, pull requests and reviews, releases and attachments,
+  secrets and variables, webhooks, admin and sudo, notifications, current-user features,
+  generic packages, and a workflow run on an `act_runner` container).
+- `test_sweep.py`: every one of the 538 tools is called once against a seeded instance
+  (`sweep_seed.py` creates the data, `sweep_plan.py` builds arguments and expectations).
+  Order: read-only first, then creates, updates and deletes (leaf resources first). A call
+  passes with a 2xx, a status the swagger documents for that operation, or an entry of
+  `ALLOWANCES` (each with a reason). All failing tools are listed at once.
+  `sweep_baseline.json` pins the outcome class of every tool (`2xx`, or the exact status of
+  a documented non-2xx or allowance). A downgrade (2xx to anything else, or a different
+  status) fails the run and all of them are reported together, so an argument or path
+  regression cannot hide behind a documented 404. An upgrade only prints a note to refresh
+  the file. Regenerate it with `AEGIS_IT_WRITE_BASELINE=1` (only for an intended change,
+  and review the diff). `test_sweep_isolated.py` covers the tools the sweep must not call.
+- `test_failure_paths.py`: write tools Gitea refuses (missing repository, invalid color,
+  duplicate repository, stale file sha) keep their status and error kind and are audited.
+- `test_per_user_oauth.py`: the HTTP app with per-user OAuth, driven in process with a
+  seeded OAuth store; calls run as the signed-in user, admin tools and private repositories
+  of others are refused by Gitea, the static bearer still runs as admin.
+- `test_setup_live.py`: `aegis-gitea-mcp setup` against the instance (OAuth app, env file
+  mode, idempotence, non-admin token).
+- `tests/test_sweep_plan.py` (no Docker) keeps the sweep plan consistent with the catalog.
+
+`AEGIS_IT_WRITE_REPORT=1` makes the session write `docs/integration-coverage.md` (per
+domain: tools with a 2xx, documented non-2xx statuses, allowances).
+
+### Actions runner
+
+`start_runner` starts `gitea/act_runner` (digest-pinned in `ACT_RUNNER_IMAGE`) on the run's
+network, registered with a token from `gitea_actions_repo_create_runner_registration_token`,
+label `aegis-host:host`. Jobs run inside the runner container itself: no Docker socket, no
+bind mounts. The runner reaches Gitea by container name, so it works in both network modes.
+It is removed with the rest of the run. If it cannot start or come online, the test is
+marked xfail with the reason, unless `CI` or `AEGIS_IT_REQUIRE_RUNNER=1` is set (the CI job
+sets it), in which case it fails: a pipeline must not silently skip the Actions scenario. A
+failure after the run completed is always a real failure.
+
+With the runner the scenario also exercises the completed run: the runner get, update and
+delete tools at repository scope, the logs archive, rerun of the run and of one job, and
+deleting the run. `test_runner_management_at_every_scope` registers one more runner for the
+organization, the user and the instance (each serving its own label) and manages it through
+the matching tools.
+
+Runtime: about two minutes locally (Gitea start 15 s, sweep 40 s, runner 10 s).
