  poppi publishes no developer program and no API keys. There are two distinct auth surfaces, and they are
  not the same product: the agent commerce MCP endpoint is ANONYMOUS (tools/list returned 200 with no
  credential), while customer accounts on the storefront run OAuth 2.0 / OpenID Connect against the store's
  own Shopify Customer Accounts tenant. Both were probed directly, not inferred from docs.

  description: >-
    The UCP MCP endpoint accepts unauthenticated JSON-RPC. No Authorization header was sent and tools/list
    returned HTTP 200 with the full tool manifest. Payment is gated by buyer approval at
    complete_checkout, not by an API credential.
