Removing it would allow any valid Nextcloud token to access the MCP server, including tokens issued for completely different purposes. + +## Decision + +Make the MCP server act as its own **OAuth Authorization Server proxy** (intermediary pattern). The MCP server advertises itself as the AS, handles client registration and authorization, but proxies the actual authentication to Nextcloud using its own credentials. This ensures all tokens have the correct audience. + +### Flow Overview + +``` +Client MCP Server (AS Proxy) Nextcloud (IdP) + | | | + |-- POST /oauth/register ----->| ---- proxy DCR --------------->| + |<---- client_id, etc. --------|<---- client_id, etc. ----------| + | | | + |-- GET /oauth/authorize ----->| (store client params) | + | (client_id, redirect, | redirect with MCP's client_id | + | code_challenge, state) |------- GET /authorize -------->| + | | (MCP client_id, MCP callback) | + | | | + | | [user authenticates] | + | | | + | |<------ code + state -----------| + | | (exchange code server-side) | + | |------- POST /token ----------->| + | | (code, MCP client_id+secret) | + | |<------ NC token (aud=MCP) -----| + | | | + | | (generate proxy_code, store | + | | mapping to NC token) | + |<-- redirect to client -------| | + | (proxy_code, state) | | + | | | + |-- POST /oauth/token -------->| (verify PKCE, lookup code) | + | (proxy_code, code_verifier) | return stored NC token | + |<---- access_token -----------| | + | | | + |-- POST /mcp (Bearer token) ->| verify_access_token() | + | (NC token with aud=MCP ✓) | _has_mcp_audience() → PASS | +``` + +### Key Design Decisions + +#### 1. PKCE Handling — Local Verification + +The MCP server receives the client's `code_challenge` but does **not** forward it to Nextcloud. Instead: + +- **Nextcloud side**: MCP server authenticates as a confidential client (`client_id` + `client_secret`), so PKCE is not required +- **Client side**: MCP server verifies PKCE locally when the client exchanges the proxy code at `/oauth/token` + +This avoids the impossible situation where the server would need the `code_verifier` to exchange code with Nextcloud but doesn't have it (only the client does). + +#### 2. In-Memory Proxy Code Storage + +Proxy codes (the authorization codes issued by the AS proxy to clients) use in-memory storage rather than SQLite because: + +- They have a 60-second TTL +- They are single-use (deleted on exchange) +- They only exist during the brief OAuth flow +- The MCP server is single-instance + +#### 3. PRM Points to MCP Server + +The `authorization_servers` field in the PRM response now points to the MCP server URL instead of Nextcloud's public URL. This is what triggers the entire proxy flow — clients discover the MCP server as their AS. + +#### 4. DCR Proxy + +Client registration requests at `/oauth/register` are proxied to Nextcloud's DCR endpoint. The resulting `client_id` is stored in the local `ClientRegistry` so that `/oauth/authorize` can validate it. The client receives the same DCR response it would get from Nextcloud directly. + +## Alternatives Considered + +### 1. Relax Audience Validation + +Remove `_has_mcp_audience()` check entirely. **Rejected**: Violates RFC 7519 security model. + +### 2. Client Pre-Registration + +Require clients to register directly with Nextcloud and configure the MCP server with their `client_id`. **Rejected**: Poor UX, doesn't work with DCR-based clients like Claude Code. + +### 3. Token Exchange (RFC 8693) + +The MCP server could accept any Nextcloud token and exchange it for one with the correct audience. **Rejected**: Nextcloud's OIDC app doesn't support RFC 8693 token exchange. This was already explored in ADR-005. + +### 4. Custom Audience Configuration + +Add configuration to accept specific external `client_id` values as valid audiences. **Rejected**: Requires manual configuration per client, doesn't scale with DCR. + +## New Endpoints + +| Endpoint | Method | Purpose | +|----------|--------|---------| +| `/.well-known/oauth-authorization-server` | GET | RFC 8414 AS metadata | +| `/oauth/authorize` | GET | Authorization (modified: intermediary, not pass-through) | +| `/oauth/token` | POST | Token exchange (proxy codes + refresh token proxy) | +| `/oauth/register` | POST | DCR proxy to Nextcloud | + +## Files Modified + +| File | Changes | +|------|---------| +| `nextcloud_mcp_server/auth/oauth_routes.py` | New: `oauth_as_metadata`, `oauth_register_proxy`, `oauth_token_endpoint`, `_oauth_callback_as_proxy`.
