# OAuth · Discovery: authorization server

GET https://api.modulards.com/.well-known/oauth-authorization-server

RFC 8414 authorization server metadata for MCP clients. Unauthenticated, no `/api` prefix — this route lives at the host root.

Every scope listed in `scopes_supported` is registered with Passport, so a client may request all of them; an unregistered scope would fail the authorization request with `invalid_scope`.

RFC 8414 also permits inserting the path component (`/.well-known/oauth-authorization-server/mcp`) — that nested variant serves the identical document.
