UCPhub

Make your store discoverable and buyable by AI shopping agents through the Universal (UCP)

Visit UCPhub

UCPhub is an implementation of the Universal Commerce Protocol (UCP), an open protocol for agentic commerce co-developed by Google, Shopify, Etsy, Wayfair, Target and Walmart. It targets commerce platforms that don't ship UCP natively. The product consists of a spec-tracked UCP Core (kept to the latest UCP spec, tracked to 2026-04-08), a connector framework (one connector per commerce platform), business-side UCP endpoints (product, offer, checkout, identity, order) over REST + JSON-RPC, and a platform-side reference agent at app.ucphub.ai/demo for building and testing AI shopping agents. Merchants publish a /.well-known/ucp discovery endpoint with an agent allowlist, so only approved agents can transact. UCPhub is compatible with AP2, A2A and MCP.
