OAuth 2.0 authorization-server metadata (RFC 8414) with OpenID fallback: tries /.well-known/oauth-authorization-server then /.well-known/openid-configuration and returns the issuer, authorization/token/revocation/introspection/device endpoints, grant types, PKCE support, token auth methods, scopes, DPoP and PAR support. Also checks /.well-known/oauth-protected-resource for MCP-style resource metadata. $0.01 per server.
