method: probed
source: live HTTP probes of every host in apis.yml, every OpenAPI servers[] host, the docs/console host
  and the MCP host, 2026-09-17
note: 'Five discovery paths were probed on six hosts (36 probes). Two real documents are served, both
  on the API/MCP hosts rather than the website: RFC 8414 OAuth authorization server metadata on api.flagsmith.com,
  and RFC 9728 OAuth protected resource metadata on mcp.flagsmith.com (which names api.flagsmith.com as
  its authorization server — the pair is what lets an MCP client complete OAuth against Flagsmith with
  no configuration). No security.txt, api-catalog, openid-configuration or ai-plugin.json is served on
  any host. Every 404 recorded below is a real 404 body, not an SPA shell.


  MCP-host OAuth discovery added 2026-09-19 (roadmap#321/#337): the harvest visits a provider''s primary
  hosts, and RFC 9728 protected-resource metadata lives on the MCP host, so these documents existed and
  were invisible to the scorer. Fetched live and validated on `resource`/`issuer`; one negative control
  per host.'
