When OAuth is enabled, the AI service discovers the authorization server by sending an unauthenticated request to the MCP server `url` and reading the `resource_metadata` link from the `WWW-Authenticate` header in the `401` response (per https://datatracker.ietf.org/doc/html/rfc9728[RFC 9728]).

Some MCP servers expose separate endpoints for unauthenticated and OAuth-protected access. The `url` must point to the endpoint that returns this metadata. Using the wrong endpoint causes the `initialize` call to hang indefinitely (see <<mcp-troubleshooting>>).

TIP: To verify the correct endpoint, send an unauthenticated request and inspect the `WWW-Authenticate` header. It should contain a `resource_metadata` URL: `curl -sI -X POST \https://mcp.example.com/v1/mcp/auth -H "Content-Type: application/json" | grep -i www-authenticate`

|The MCP server `url` in `MCP_SERVERS` does not return OAuth resource discovery metadata (https://datatracker.ietf.org/doc/html/rfc9728[RFC 9728]). The AI service sends an unauthenticated request to the URL and expects a `401` response with a `WWW-Authenticate` header containing a `resource_metadata` link. If the header is missing, the service hangs indefinitely. Verify the correct endpoint with: `curl -sI -X POST \https://mcp.example.com/endpoint -H "Content-Type: application/json"` and check for `resource_metadata` in the `WWW-Authenticate` header. Some MCP servers expose separate URLs for authenticated and OAuth-protected access. See <<mcp-oauth-url>>.
