TRUFF

TRUFF Store UCP Shopping API

The agent-facing commerce surface for TRUFF's online store. A Model Context Protocol endpoint at https://shop.truff.com/api/ucp/mcp implements the Universal Commerce Protocol dev.ucp.shopping service (version 2026-08-25, with 2026-04-08 and 2026-01-23 still supported) and answers unauthenticated with 13 tools covering catalog search and lookup, product detail, cart create / read / update / cancel, checkout create / read / update / complete / cancel, and order lookup. complete_checkout requires an idempotency key and, per the store's published agent instructions, contemporaneous buyer approval before payment. The implementation is emitted by the Shopify platform for every store on it; the endpoint, the merchant identity and the data are TRUFF's.
