HAYLOU Commerce (UCP/MCP)

The HAYLOU brand storefront exposes an agent-facing commerce surface over the Universal Commerce Protocol, reachable as a live MCP endpoint. Agents can search the catalog, build a cart, create and update a checkout, and complete a purchase, alongside fulfillment, discount and order capabilities. Checkout requires explicit contemporaneous buyer approval before any payment is completed, and the endpoint is rate-limited per IP. The store also serves an llms.txt and agents.md describing read-only browsing routes for agents that only need product and collection data. This surface is provisioned by Shopify, which serves UCP natively for its stores, rather than being built by Liesheng — but it is genuinely served from the haylou.com origin and is the only MCP server in the Liesheng estate.
