Rael UCP Commerce MCP
Rael's agent-facing commerce interface. The store implements the Universal Commerce Protocol (UCP) 2026-04-08 and exposes it over MCP at https://www.getrael.com/api/ucp/mcp. An anonymous tools/list returns thirteen tools — search_catalog, lookup_catalog, get_product, create/get/update/cancel_cart and create/get/update/complete/cancel_checkout, plus get_order — each with a full JSON Schema inputSchema. Checkout completion requires contemporaneous buyer approval; the endpoint is rate limited per IP and returns Shopify complexity-score headers.
