UrbanStems Commerce MCP API is one of 2 APIs that [UrbanStems](https://apis.io/providers/urbanstems/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Commerce, Catalog, Cart, Checkout, and Orders. The published artifact set on APIs.io includes API documentation, authentication docs, and rate-limit docs.

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.
