Hubble Contacts UCP Commerce (MCP) is one of 3 APIs that [Hubble Contacts](https://apis.io/providers/hubble-contacts/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Agentic Commerce, MCP, Universal Commerce Protocol, Checkout, and Catalog.

Agent-facing commerce surface for the Hubble Contacts online store, implementing the Universal Commerce Protocol (UCP) over MCP/JSON-RPC. Hubble's own /agents.md documents the flow: discover capabilities at /.well-known/ucp, then call search_catalog, create_cart, create_checkout, update_checkout and complete_checkout against the MCP endpoint. Checkout requires contemporaneous buyer approval; the endpoint is rate limited per IP. tools/list is gated behind a registered UCP agent profile, so live tool input schemas require an authenticated agent identity. Served on Hubble's host and provided natively by the Shopify platform.
