- Expose Protected Resource metadata endpoint
- proxy some path to overcome this issue on Claude Web side : Claude.ai ignores authorization_endpoint and token_endpoint from OAuth metadata when MCP server uses external authorization server anthropics/claude-ai-mcp#82

…to overcome this issue on Claude Web side : anthropics/claude-ai-mcp#82
…odes Both modes now read the bearer token from the request scope via FastMCP's `get_access_token()`. `GitGuardianOAuthThinProxy.verify_token` no longer round-trips to `/api_tokens/self` per request — a new `PassThroughTokenVerifier` trusts the token and lets downstream calls surface 401s. `GitGuardianAuthorizationHeaderMCP` reuses the same verifier so the manual `Authorization` header parser is gone. Issue: APPAI-524

When `TranslateDownstreamUnauthorizedMiddleware` flips a 200 into a 401, the response has no `WWW-Authenticate` header for the advertise middleware to augment, so it synthesizes one. Previously it emitted only `as_metadata` — the Claude.ai-specific shortcut — leaving spec-compliant MCP clients (Cursor, MCP Inspector) without the standard `resource_metadata` discovery pointer required by RFC 9728. `resource_metadata_url_provider` is resolved lazily because FastMCP calls `get_middleware()` before `set_mcp_path()`, so the resource URL is not known at middleware construction time. Issue: APPAI-524
