  summary: 'Documentation corpus is partner-login-gated in the browser but readable
    anonymously through this MCP endpoint.'
  detail: 'Every HTML path on docs.cardless.com redirects to /login?redirect=... , and
    docs.cardless.com/sitemap.xml is empty — the documentation is deliberately gated to
    partners. The MCP endpoint at docs.cardless.com/mcp nonetheless answers tools/list
    and tools/call with no credentials, and its query_docs_filesystem tool exposes the
    gated corpus, including OpenAPI fragments under /openapi/api-reference/ (applications/schema.yaml,
    authentication/get-token.yaml) and /openapi/not used/payment-plans/. API Evangelist
    recorded the existence and shape of that contract as catalog metadata but deliberately
    did NOT copy the gated specification or documentation bodies into this public repo.
    Reported here as a finding for Cardless, not republished.'
