quip UCP Commerce MCP API
An anonymous Model Context Protocol endpoint implementing the Universal Commerce Protocol (UCP) shopping service for the quip online store. Exposes thirteen tools covering catalog search and lookup, product detail, cart lifecycle, checkout lifecycle and order retrieval, each carrying a full JSON Schema 2020-12 input contract. tools/list and initialize are anonymous; every tools/call requires a resolvable UCP agent profile URI. Checkout completion requires contemporaneous human buyer approval per the store's published agent rules, and no API-level reversal of a completed checkout exists.
