  Derived by hand from probed discovery documents, not from an OpenAPI: ModifyHealth
  publishes no spec, so 0-working/derive-authentication.py had nothing to read. Two
  distinct auth surfaces exist and must not be conflated.

    The MCP endpoint requires no credential. tools/list returns HTTP 200 with all 13
    tools and full inputSchemas anonymously. Tool invocation requires a meta.ucp-agent
    profile URI, which is an agent identity hint for UCP discovery, not a secret.

  detail: >-
    Customer-account sign-in for the ModifyHealth storefront, delegated to Shopify as the
    authorization server. The oauth-protected-resource document served at
    modifyhealth.com names resource https://modifyhealth.com with authorization_servers
    [https://shopify.com/authentication/7887683702], which is what makes the cross-domain
    issuer legitimate rather than a mismatch.
