  Hosted agent-commerce MCP server exposed natively by CRU Kafe's Shopify storefront
  via the Universal Commerce Protocol (UCP). Lets agents search the catalog, build a
  cart, and drive a buyer-approved checkout. Not a first-party CRU Kafe build - it is
  the Shopify/UCP platform surface served on the crukafe.com domain.
