Live remote MCP server implementing the Universal Commerce Protocol shopping service (version 2026-04-08) on Johnnie-O's Shopify-served primary domain. An anonymous JSON-RPC tools/list returns thirteen tools with complete input schemas — search_catalog, lookup_catalog, get_product, create_cart, get_cart, update_cart, cancel_cart, create_checkout, get_checkout, update_checkout, complete_checkout, cancel_checkout and get_order. Tool invocation is gated on a UCP agent profile URI. Capabilities declared at /.well-known/ucp cover checkout, cart, fulfillment and discount, with Shop Pay, card and Google Pay payment handlers. The store's own llms.txt requires explicit buyer approval before any agent completes payment.
