Probed 2026-09-02. note: >- Two real documents are served, both on the OAuth/MCP side of the estate. api.unified.com and mcp.unified.com run the same FastAPI build ("unified-mcp-service" 0.0.59, build 66) and both answer /.well-known/oauth-authorization-server with an RFC 8414 document whose issuer is https://mcp.unified.com/. The RFC 9728 protected-resource descriptor is NOT at the bare /.well-known/oauth-protected-resource path (404); it is at the resource-suffixed /.well-known/oauth-protected-resource/mcp, which is the exact location the 401 challenge's WWW-Authenticate resource_metadata parameter names. No security.txt, api-catalog, ai-plugin, openid-configuration, UCP/ACP, AAuth resource or agent card is served on any host. www.unified.com is a Netlify-hosted SPA that returns a 1.4 MB HTML 404 body for every unknown path — recorded as a miss, not a document. hit_count: 3 path_echo_control: passed soft_404_control: - host: https://www.unified.com path: /.well-known/unified-negative-control-7f3ab91c.json status: 404 bytes: 1436692 verdict: SPA 404 shell, correct status code, no false 200 - host: https://api.unified.com path: /.well-known/unified-negative-control-7f3ab91c.json status: 404 bytes: 9 verdict: plain "Not Found", no path echo - host: https://mcp.unified.com path: /.well-known/unified-negative-control-7f3ab91c.json status: 404 bytes: 9 verdict: plain "Not Found", no path echo hosts: - host: https://api.unified.com documents: - path: /.well-known/oauth-authorization-server status: 200 file: unified-oauth-authorization-server.json - path: /.well-known/oauth-protected-resource status: 404 - path: /.well-known/security.txt status: 404 - path: /.well-known/openid-configuration status: 404 - path: /.well-known/api-catalog status: 404 - path: /.well-known/ai-plugin.json status: 404 - path: /.well-known/ucp.json status: 404 - path: /.well-known/acp.json status: 404 - path: /.well-known/aauth-resource.json status: 404 - path: /.well-known/agent-card.json status: 404 - path: /.well-known/agent.json status: 404 - host: https://mcp.unified.com documents: - path: /.well-known/oauth-authorization-server status: 200 file: unified-oauth-authorization-server.json - path: /.well-known/oauth-protected-resource/mcp status: 200 file: unified-oauth-protected-resource.json - path: /.well-known/oauth-protected-resource status: 404 - path: /.well-known/security.txt status: 404 - path: /.well-known/openid-configuration status: 404 - path: /.well-known/api-catalog status: 404 - path: /.well-known/ai-plugin.json status: 404 - path: /.well-known/ucp.json status: 404 - path: /.well-known/acp.json status: 404 - path: /.well-known/aauth-resource.json status: 404 - path: /.well-known/agent-card.json status: 404 - path: /.well-known/agent.json status: 404 - host: https://www.unified.com documents: - path: /.well-known/security.txt status: 404 - path: /.well-known/openid-configuration status: 404 - path: /.well-known/oauth-authorization-server status: 404 - path: /.well-known/oauth-protected-resource status: 404 - path: /.well-known/api-catalog status: 404 - path: /.well-known/ai-plugin.json status: 404 - path: /.well-known/ucp.json status: 404 - path: /.well-known/acp.json status: 404 - path: /.well-known/aauth-resource.json status: 404 - path: /.well-known/agent-card.json status: 404 - path: /.well-known/agent.json status: 404 - host: https://get.unified.com documents: - path: /.well-known/security.txt status: 302 - path: /.well-known/openid-configuration status: 302 - path: /.well-known/oauth-authorization-server status: 302 - path: /.well-known/oauth-protected-resource status: 302 - path: /.well-known/api-catalog status: 302 - path: /.well-known/ai-plugin.json status: 302 - path: /.well-known/agent-card.json status: 302 - path: /.well-known/agent.json status: 302 note: >- Every /.well-known/ path on the customer application host 302s to the login flow; nothing is served anonymously. - host: https://docs.unified.com documents: - path: /.well-known/security.txt status: 307 - path: /.well-known/openid-configuration status: 307 - path: /.well-known/oauth-authorization-server status: 307 - path: /.well-known/oauth-protected-resource status: 307 - path: /.well-known/api-catalog status: 307 - path: /.well-known/ai-plugin.json status: 307 - path: /.well-known/agent-card.json status: 307 - path: /.well-known/agent.json status: 307 note: >- GitBook-hosted docs space; every path 307s into the iheartmedia.unified.com SSO login.
