LINSY HOME UCP Commerce API (MCP)
The Universal Commerce Protocol (UCP) agent-commerce surface for the LINSY HOME storefront (www.linsyhome.com, Shopify shop linsy-home.myshopify.com). Agents discover the merchant profile at /.well-known/ucp and call the MCP endpoint over JSON-RPC to search the catalog, look up products, create and update carts, start and update a checkout, and complete a purchase with buyer approval. Supported UCP versions are 2026-04-08 (latest stable) and 2026-01-23.
