method: probed
source: live GET probes of /.well-known/* on every Moz API host
note: 'moz.com serves a real RFC 9116 security.txt. api.moz.com serves RFC 8414 OAuth authorization server
  metadata and RFC 9728 OAuth protected-resource metadata for each of the two beta MCP endpoints; note
  the protected-resource documents are only served at the per-resource paths (/.well-known/oauth-protected-resource/mcp/v1/{data,local}),
  not at the bare /.well-known/oauth-protected-resource root, which 404s.


  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.'
