Adds a create_label write-mode tool so labels can be created in a repository
through the MCP server (previously there was no way to define labels, which
blocked attaching labels to issues). Follows the full tool checklist:
- arguments.py: CreateLabelArgs (name, hex color, optional description/exclusive),
with extra=forbid and a hex-color pattern.
- gitea_client.py: create_label() POSTing to /repos/{owner}/{repo}/labels with
url-encoded path segments.
- write_tools.py: create_label_tool handler; normalizes the color to a leading
'#', bounds text output, and lets auth/authz errors surface.
- mcp_protocol.py: register create_label (write_operation=True).
- server.py: wire create_label into TOOL_HANDLERS.
- docs/api-reference.md: document create_label.
- tests: success path, color normalization, and invalid-color rejection.

# API Reference
|
|
|
|
## Core Endpoints
|
|
|
|
- `GET /`: server metadata.
|
|
- `GET /health`: health probe.
|
|
- `GET /metrics`: Prometheus metrics (when enabled).
|
|
|
|
## OAuth Discovery and Token Exchange
|
|
|
|
- `GET /.well-known/oauth-protected-resource`
|
|
- Returns OAuth protected resource metadata used by MCP clients.
|
|
- `GET /.well-known/oauth-authorization-server`
|
|
- Returns OAuth authorization server metadata.
|
|
- `POST /register`
|
|
- Registers an OAuth client and persists the client metadata.
|
|
- `POST /oauth/token`
|
|
- Proxies OAuth authorization-code token exchange to Gitea.
|
|
|
|
## MCP Endpoints
|
|
|
|
- `GET /mcp/tools`: list tool definitions.
|
|
- `GET /mcp` and `POST /mcp`: streamable HTTP transport.
|
|
- `GET /mcp/sse` and `POST /mcp/sse`: MCP SSE transport alias.
|
|
- `POST /mcp/tool/call`: direct tool-call endpoint.
|
|
|
|
Authentication requirements:
|
|
|
|
- MCP tool execution requires `Authorization: Bearer <token>`.
|
|
- Missing or invalid tokens return `401` with:
|
|
- `WWW-Authenticate: Bearer resource_metadata="<absolute metadata url>", scope="read:repository"`
|
|
|
|
Scope requirements:
|
|
|
|
- Read tools require `read:repository`.
|
|
- Write tools require `write:repository`.
|
|
- Insufficient scope returns `403`.
|
|
|
|
## Automation Endpoints
|
|
|
|
- `POST /automation/webhook`: ingest policy-controlled webhook events.
|
|
- `POST /automation/jobs/run`: run policy-controlled automation jobs.
|
|
|
|

|
- File reads are capped by `MAX_FILE_SIZE_BYTES`.
|
|
|
|
## Error Model
