UrbanStems

UrbanStems Commerce MCP API

The agent-facing commerce surface for the UrbanStems store, implementing the Universal Commerce Protocol (dev.ucp.shopping) over MCP. Thirteen tools cover catalog search and lookup, product detail, cart create/update/cancel, checkout create/update/complete/cancel, and order retrieval. Anonymous — no API key or OAuth token is required to list tools or search the catalog — but completing a checkout requires an idempotency key and contemporaneous buyer approval of payment.
