generated: '2026-09-07' method: probed source: live probes of /.well-known/ on all four Cambio Uruguay hosts, 2026-09-07 summary: >- One real document is served: an RFC 9116 security.txt on the apex (and identically on www), saved verbatim to cambio-uruguay-security.txt. Everything else 404s cleanly on every host — no OIDC discovery, no OAuth server/resource metadata (the MCP server is anonymous, so none is expected), no api-catalog, no ai-plugin.json, and no A2A agent card on either the canonical /.well-known/agent-card.json or the legacy /.well-known/agent.json path. pointer_basis: >- WellKnown and SecurityTxt pointers are emitted on the strength of the 200 on https://cambio-uruguay.com/.well-known/security.txt, whose body is a real RFC 9116 document (Contact, Expires, Preferred-Languages, Canonical, Policy, Acknowledgments). Caveats recorded honestly: it is served with content-type application/json instead of text/plain, its Expires (2026-06-09) had already passed when probed on 2026-09-07, and its Policy and Acknowledgments URLs both return 404 (see security/cambio-uruguay-vulnerability-disclosure.yml). hosts: - host: https://cambio-uruguay.com documents: - path: /.well-known/security.txt status: 200 file: cambio-uruguay-security.txt note: content-type application/json (body is valid RFC 9116 text); Expires 2026-06-09 already past at probe time - 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/agent-card.json status: 404 - path: /.well-known/agent.json status: 404 - host: https://www.cambio-uruguay.com documents: - path: /.well-known/security.txt status: 200 file: cambio-uruguay-security.txt note: identical body to the apex copy; not saved twice - 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/agent-card.json status: 404 - path: /.well-known/agent.json status: 404 - host: https://api.cambio-uruguay.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/agent-card.json status: 404 - path: /.well-known/agent.json status: 404 - host: https://mcp.cambio-uruguay.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/agent-card.json status: 404 - path: /.well-known/agent.json status: 404
