generated: '2026-09-19' method: searched description: 'Probe of the /.well-known/ discovery surface on every host the record knows: kimetsu.dev (website + docs), www.kimetsu.dev (301s every path to the apex), and agents.kimetsu.dev (the OpenAPI servers[0] host, the A2A card host and the A2A endpoint host). There is no hosted MCP host to probe: Kimetsu''s MCP server is a local stdio binary and Kimetsu Remote is self-hosted by each operator. The Sidequest Commons human site is a GitHub Pages path (rodcor.github.io/sidequest-commons) and 404s both agent-card paths. Every 404 on kimetsu.dev is a real HTTP 404 with the site''s 13,236-byte HTML 404 page; every 404 on agents.kimetsu.dev is a real HTTP 404 with the JSON body {"error":"not_found"}. A negative-control path 404d on both hosts. The two extra rows beyond the closed list (/.well-known/kimetsu-agents.json and /agent-gateway.json) were probed only because robots.txt, llms.txt and the discovery manifest''s own fallback field name them — no glob was used. No OAuth/OIDC discovery document exists on any host, which matches the provider''s stated model: every gateway read is anonymous and credentials are rejected with 400.' path_echo_control: passed negative_control: /.well-known/kimetsu-dev-negative-control-a768ab07.json -> 404 on kimetsu.dev and agents.kimetsu.dev (301 to apex on www) hit_count: 5 hosts: - host: https://kimetsu.dev role: website + docs documents: - path: /.well-known/security.txt status: 404 type: text/html note: HTML 404 page (HTTP 404) - path: /.well-known/openid-configuration status: 404 type: text/html - path: /.well-known/oauth-authorization-server status: 404 type: text/html - path: /.well-known/oauth-protected-resource status: 404 type: text/html - path: /.well-known/api-catalog status: 404 type: text/html - path: /.well-known/api-catalog.json status: 404 type: text/html - path: /.well-known/ai-plugin.json status: 404 type: text/html - path: /.well-known/ucp.json status: 404 type: text/html - path: /.well-known/acp.json status: 404 type: text/html - path: /.well-known/aauth-resource.json status: 404 type: text/html - path: /.well-known/apis.json status: 404 type: text/html - path: /apis.json status: 404 type: text/html - path: /apis.yml status: 404 type: text/html - path: /.well-known/agent-card.json status: 404 type: text/html - path: /.well-known/agent.json status: 404 type: text/html - path: /.well-known/mcp.json status: 404 type: text/html - path: /.well-known/kimetsu-agents.json status: 200 type: application/json file: kimetsu-dev-kimetsu-agents.json note: Provider-defined domain-level discovery pointer (schema https://kimetsu.dev/schemas/well-known-agent-directory-v1.schema.json, saved in json-schema/).
