note: >-
  No OpenAPI exists to derive from, so this profile is read directly from the two OAuth discovery
  documents the provider's host serves (RFC 8414 and RFC 9728, both HTTP 200 on 2026-09-18) and
  from the WWW-Authenticate challenge observed on the MCP endpoint. It describes the WordPress MCP
  adapter's authorization server, the only authenticated machine surface on the domain; the
  company publishes no product API, no API keys and no developer authentication documentation.
