# Valuable references for the reviewer: - Docs PR: https://github.com/ArcadeAI/docs/pull/583 - Implements Phase 1 of the following planning doc: https://linear.app/arcadedev/project/arcade-mcp-supports-mcp-auth-front-door-auth-7cbaa20cb054/overview https://github.com/user-attachments/assets/79ad43fd-f5e8-4793-a1dd-18b35acefdc3 # PR Description Adds OAuth 2.1 Resource Server authentication to arcade-mcp-server, enabling HTTP MCP servers to validate Bearer tokens on every request. This unlocks tool-level authorization and secrets support for HTTP servers. - Multiple authorization server support - Granular token validation options (verify_exp, verify_iat, verify_iss) - Environment variable configuration - OAuth discovery metadata endpoint (/.well-known/oauth-protected-resource) - Extracts sub claim from token as context.user_id - Lifts transport restrictions for tools requiring auth/secrets on HTTP when protected ```python from arcade_mcp_server import MCPApp from arcade_mcp_server.resource_server import ResourceServerAuth, AuthorizationServerEntry resource_server_auth = ResourceServerAuth( canonical_url="http://127.0.0.1:8000/mcp", authorization_servers=[ AuthorizationServerEntry( authorization_server_url="https://auth.example.com", issuer="https://auth.example.com", jwks_uri="https://auth.example.com/jwks", ) ], ) app = MCPApp(name="my_server", version="1.0.0", auth=resource_server_auth) ``` # Testing Beyond the comprehensive unit tests, I also manually tested end-to-end with WorkOS Authkit (DCR) and KeyCloak (non-DCR). # Future Work - CIMD support - An `ArcadeResourceServer` to make adding front-door auth super easy when using Arcade's Auth Server <!-- CURSOR_SUMMARY --> --- > [!NOTE] > Adds OAuth 2.1 front-door auth (JWKS validation + OAuth discovery) and propagates user identity to tools, enabling auth/secret-requiring tools over HTTP. > > - **Authentication (Front-Door OAuth 2.1)** > - New `resource_server` module with `ResourceServerAuth` (multi-authorization-server, metadata) and `JWKSTokenValidator` (JWKS-based JWT validation) plus granular validation options. > - ASGI `ResourceServerMiddleware` validates Bearer tokens on every HTTP request and injects `resource_owner`. > - OAuth discovery endpoint via FastAPI router at `/.well-known/oauth-protected-resource[/<path>]`. > - **Integration** > - `MCPApp`/`worker` accept `auth`/`resource_server_validator`, mount middleware, expose discovery; logs accepted auth servers. > - HTTP transport (`http_streamable`) carries `SessionMessage` with `resource_owner` from request → session. > - `Context`/`Session`/`Server` plumb `resource_owner`; `Server` selects `user_id` preferring token `sub`. > - **Behavior Changes** > - HTTP transport restriction lifted for tools requiring `authorization`/`secrets` when request is authenticated; otherwise blocked with actionable error. > - **Configuration** > - Env-var based auth config via `MCP_RESOURCE_SERVER_*` in `MCPSettings.ResourceServerSettings`; `.env` auto-load. > - **Telemetry** > - Usage tracking records `resource_server_type` on server start. > - **Examples** > - New `examples/mcp_servers/authorization` sample server (HTTP auth, secrets, Reddit tool) with Docker setup. > - **Tests** > - Extensive unit tests for validators, middleware, env config, multi-AS, transport rules, and app integration. > - **Version** > - Bump `arcade-mcp-server` to `1.12.0`; minor docstring tweak in `__init__.py`. > > <sup>Written by [Cursor Bugbot](https://cursor.com/dashboard?tab=bugbot) for commit d1116cdcafb0c7cb8f91e66682eb1fbae380da31.
