notes: >-
  REST API uses OAuth 2.0 client-credentials: exchange base64 client_id:client_secret
  (HTTP Basic) at POST /oauth/token for a Bearer access token (access_token,
  expires_in, refresh_token). All other endpoints take Authorization: Bearer <token>
  (an API Key or OAuth access token). The published MCP server uses the OAuth 2.0
  authorization-code flow with PKCE backed by Auth0, and advertises Dynamic Client
  Registration (RFC 7591) so clients need no pre-configured client_id.
