  Authentication profile derived from Supper's published RFC 8414 OAuth 2.0
  Authorization Server Metadata and the /mcp connection docs. Supper's MCP
  server is an OAuth 2.0 public client (PKCE S256) supporting Dynamic Client
  Registration; end users authorize via one-click OAuth in Claude. No API-key
  or basic-auth surface is documented publicly (developer docs are gated).
