generated: '2026-09-19' method: probed source: >- Live GET probes of the named /.well-known/* path list on rsperformance.online, www.rsperformance.online, ai.rsperformance.online (the OpenAPI servers[] host and gateway) and mcp.rs3d.pl (the MCP server host), 2026-09-19. Every row below is a request that was actually issued; every status is the one returned. A row carries file: only when a real, non-HTML document was fetched and saved. summary: hosts_probed: 4 paths_probed: 64 documents_served: 20 path_echo_control: passed documents_saved: 17 note: >- RS Performance serves an unusually dense agent-discovery surface for a single-location auto workshop: an RFC 9116 security.txt (on the apex and the gateway), an OpenAI-style ai-plugin.json whose api.type is "mcp", a non-standard mcp.json naming two remote MCP servers, an A2A agent card at both the canonical and legacy paths (two DIFFERENT cards), an OpenAPI at /.well-known/openapi.json on both web hosts, and a family of provider-defined manifests (ai-resources.json, agents.json, mcp-agent-card.json, aeo-editorial-gate.json, priority-answer-paths.json, freshness.json, answer-routing.json). NONE of the OAuth/OIDC discovery documents exist on any host — the whole surface is anonymous — and there is no RFC 9727 api-catalog, no APIs.json, no UCP/ACP and no AAuth resource document. The MCP host serves no well-known document at all. negative_control: >- /.well-known/rsperformance-online-negative-control-9c2e41ab.json returned 404 on rsperformance.online (HTML "Not Found" page, 6,586 bytes), 404 on ai.rsperformance.online (empty body) and 404 on mcp.rs3d.pl ("Not Found", 9 bytes). No host echoes the requested path, so the 200s below are real. soft_404_shape: >- rsperformance.online answers unknown paths with a 6,586-byte HTML "Not Found" page (Laravel 404) and HTTP 404 — an honest status, not a catch-all 200. Each 200 below carried a JSON or text/plain body that parsed as the document type its path names. hosts: - host: rsperformance.online role: Canonical website (Laravel on cyberfolks.pl shared hosting, LiteSpeed); A2A JSON-RPC endpoint on POST / ip: 195.78.67.59 documents: - path: /.well-known/security.txt status: 200 content_type: text/plain file: rsperformance-online-security.txt standard: RFC 9116 note: Contact (mailto + https), Expires 2027-09-20 (inside one year), Preferred-Languages pl,en, Canonical, Policy, Acknowledgments.
