Both RFC 8414 (authorization server metadata) and RFC 9728 (protected resource metadata) return live JSON documents that describe how an agent authorizes against the MCP endpoint. This is a genuine hit, not an SPA catch-all: the control path and every other well-known path on this host return a hard 404 with an empty body, so the two 200s below are documents the provider deliberately publishes. documents: - path: /.well-known/oauth-authorization-server spec: RFC 8414 status: 200 content_type: application/json file: amuncore-oauth-authorization-server.json note: >- Issuer https://amuncore.com with authorization, token and dynamic client registration endpoints, authorization_code + refresh_token grants, PKCE S256 required, and a single supported scope "mcp". - path: /.well-known/oauth-protected-resource spec: RFC 9728 status: 200 content_type: application/json file: amuncore-oauth-protected-resource.json note: >- Declares https://amuncore.com/mcp as the protected resource, points back at this host as its authorization server, and names llms.txt as the resource documentation. The MCP endpoint's 401 carries a matching WWW-Authenticate: Bearer resource_metadata="..." challenge. - path: /.well-known/security.txt spec: RFC 9116 status: 404 - path: /.well-known/openid-configuration spec: OpenID Connect Discovery 1.0 status: 404 - path: /.well-known/api-catalog spec: RFC 9727 status: 404 - path: /.well-known/ai-plugin.json status: 404 - path: /.well-known/agent-card.json spec: A2A 1.0.0 status: 404 - path: /.well-known/agent.json spec: A2A legacy (pre-0.3) status: 404 control: path: /zzz-control-nonsense status: 404 note: >- Control path returns a genuine 404 with a zero-byte body, so this host has no single-page-app catch-all and the 404s recorded above are real absences rather than soft misses. gaps: - No /.well-known/security.txt — there is no machine-readable security contact or vulnerability-disclosure pointer, even though the provider publishes a human-readable security page at https://amuncore.com/security.html. - No /.well-known/api-catalog, so the OpenAPI at /openapi.json is discoverable only from llms.txt and the homepage rather than from an RFC 9727 catalog. evidence: - url: https://amuncore.com/.well-known/oauth-authorization-server status: 200 - url: https://amuncore.com/.well-known/oauth-protected-resource status: 200 - url: https://amuncore.com/.well-known/security.txt status: 404 - url: https://amuncore.com/.well-known/agent-card.json status: 404 - url: https://amuncore.com/.well-known/agent.json status: 404
