  notes: >-
    Deliberately open: the OpenAPI declares security: [] with no securitySchemes,
    the info.description states "No authentication is required", and anonymous
    probes of GET /api/calling-codes/US, GET /api/capabilities, and the MCP
    endpoint (initialize + tools/list) all succeeded with no credentials. The MCP
    Registry manifest declares authentication: none and readOnly: true. CORS
    allows cross-origin GET from any origin (access-control-allow-origin: *).
