Ole-Morten Duesund 9d3b16e7b3 test(bridge): integration test against real forgejo-mcp (forgejo-mcp-broker-xot) 
Spawns a real forgejo-mcp --transport stdio subprocess, runs the
canonical MCP handshake (initialize → notifications/initialized →
tools/list → tools/call get_forgejo_mcp_server_version) through the
bridge, and verifies each step. Validates that the opaque-pipe
assumption holds end-to-end: every JSON-RPC message round-trips
correctly with no hand-rolled framing surprises.

Binary discovery (skipped if none found):
  1. $FORGEJO_MCP_BIN
  2. ../../../forgejo-mcp/forgejo-mcp (sibling-repo built binary)
  3. go build of ../../../forgejo-mcp into a temp dir

Fake Forgejo (httptest.Server) covers the two probes the SDK and
forgejo-mcp's testConnection do at startup:
  - GET /api/v1/version → returns 11.0.0 (>=1.11.0 satisfies SDK gate)
  - GET /api/v1/user    → returns a minimal authenticated user blob

Skipped under -short. Catch-all 404 handler logs unexpected probes so
new SDK or forgejo-mcp behaviour surfaces clearly in test output.

Closes forgejo-mcp-broker-xot. Phase 4 complete.

forgejo-mcp-broker

OAuth 2.1 authorization server and MCP session broker for forgejo-mcp.

Lets MCP clients such as Claude.ai connect to a Forgejo instance through a single public HTTPS endpoint, with per-user authentication delegated to Forgejo's own OAuth2 provider. The broker handles the OAuth dance, then spawns a dedicated forgejo-mcp --transport stdio subprocess for each authenticated session, scoped to the authenticated user's Forgejo access token.

Status: Planning. No code yet. See docs/design.md for the architecture and docs/plan.md for the phased implementation plan.

How it fits

Claude.ai ──HTTPS──▶ Caddy ──▶ fjmcp-broker ──stdio──▶ forgejo-mcp  ──▶ Forgejo API
                                  (this)              (one per user     (per-user
                                                       session)          token)
  • fjmcp-broker (this project): one long-running process. Handles OAuth discovery, dynamic client registration, the authorization-code flow against Forgejo, session lifecycle, and stdio-to-streamable-HTTP bridging.
  • forgejo-mcp (existing project): used as-is. Spawned per-session with the authenticated user's FORGEJO_ACCESS_TOKEN in the environment.
  • Caddy: terminates TLS for the public hostname and reverse-proxies to the broker.

Why a broker instead of adding OAuth to forgejo-mcp?

Process-level isolation. Each user's Forgejo token lives in exactly one subprocess — the broker never needs to demultiplex tokens inside a single shared client. This keeps forgejo-mcp's sync.Once singleton-client pattern valid and avoids a refactor of every tool handler. Full trade-off in docs/design.md.
