  status: 404
  detail: Notable gap - the MCP server at search.parallel.ai/mcp-oauth requires OAuth but publishes neither
    RFC 9728 protected-resource metadata nor RFC 8414 server metadata on its own host; clients must be
    told to use platform.parallel.ai out of band.

  status: 404
notes: 'Four real documents are served from /.well-known/ across Parallel''s hosts: the RFC 8414 OAuth
  metadata on platform.parallel.ai, two A2A Agent Cards (api. and docs.), and a published Agent Skill
  markdown file on docs. No security.txt, OpenID configuration, api-catalog, or ai-plugin.json exists
  on any host. The 404 rows are recorded absences, not failures to probe.'

x-shape-fix:
  converted: '2026-08-20'
  from: probes
  note: Rewritten into hosts[] -> documents[], the only shape well_known_docs() in score.rb reads. A served
    .well-known surface recorded in any other shape scores as absent. Promoted ONLY the 2xx rows out of
    the probe log; non-2xx probes are real negative results and were left in place, not converted into
    documents.
