  Derived from the OAuth/OIDC discovery documents the storefront actually serves and from
  observed behaviour of the MCP endpoint. 3N TECH publishes no OpenAPI, so there are no
  securitySchemes to aggregate; these are Shopify Customer Account identity endpoints
  running under 3N's own hosts.

    MCP initialize and tools/list are served with no credential of any kind. tools/call
    is not open: it requires meta.ucp-agent.profile to carry a fetchable agent profile
    URI, and a call without one returns JSON-RPC error -32001 invalid_profile_url over
    HTTP 422. That is an agent-identity requirement, not a bearer credential.
