generated: '2026-08-13' method: probed source: /.well-known/ probes across every Extole host in apis.yml, every OpenAPI servers[] host, the docs host, and the MCP host note: >- Re-probed 2026-08-13 and materially upgraded. The 2026-07-19 pass found well-known documents only on the SafeBase-hosted trust portal at security.extole.com, which is a vendor surface rather than Extole's own API. That is no longer the interesting result: Extole's own MCP host, https://mcp.extole.com, now serves a real RFC 9728 protected-resource document, an RFC 8414 authorization-server document, an OIDC discovery document, AND a non-standard /.well-known/mcp toolset manifest — all anonymous, all first-party, all saved verbatim here. The API host api.extole.io continues to serve nothing at /.well-known/*, and neither extole.com nor the docs host serves a security.txt. Both facts are recorded. The WellKnown pointer in apis.yml is earned by the mcp.extole.com 200s, not asserted over a set of 404s. hosts: - host: https://mcp.extole.com first_party: true documents: - path: /.well-known/oauth-protected-resource spec: RFC 9728 status: 200 content_type: application/json file: extole-mcp-oauth-protected-resource.json - path: /.well-known/oauth-authorization-server spec: RFC 8414 status: 200 content_type: application/json file: extole-mcp-oauth-authorization-server.json - path: /.well-known/openid-configuration spec: OpenID Connect Discovery 1.0 status: 200 content_type: application/json file: extole-mcp-openid-configuration.json - path: /.well-known/mcp spec: vendor-specific MCP toolset manifest status: 200 content_type: application/json file: ../mcp/extole-mcp-manifest.json note: 31 named toolset endpoints.

Per the pipeline's search-only rule, NOTHING was written to a2a/ — no stub, no candidate. x-evidence: - fetched: '2026-08-13' url: https://mcp.extole.com/.well-known/oauth-protected-resource http_status: 200 - fetched: '2026-08-13' url: https://mcp.extole.com/.well-known/oauth-authorization-server http_status: 200 - fetched: '2026-08-13' url: https://mcp.extole.com/.well-known/openid-configuration http_status: 200 - fetched: '2026-08-13' url: https://mcp.extole.com/.well-known/mcp http_status: 200 - fetched: '2026-08-13' url: https://api.extole.io/.well-known/security.txt http_status: 404 - fetched: '2026-08-13' url: https://www.extole.com/.well-known/agent-card.json http_status: 404
