    Checkout completion requires contemporaneous buyer approval; the storefront delegates customer-account auth
    to Shopify (see well-known/arccos-golf-openid-configuration.json).
provenance_note: >-
  This MCP server is the Shopify platform's Universal Commerce Protocol commerce surface, published on the Arccos
  Golf storefront host. It exposes the online store (sensors, grips, Arccos Air, accessories) — NOT the Arccos
  On-Course Data API. There is no MCP server for the golf-data API. Recorded here because it is served from the
  provider's own domain and is anonymously discoverable and introspectable.
