Universal Commerce Protocol (UCP)
Open standard co-developed by Google and Shopify for AI agents to discover, negotiate, and transact with any merchant across the full commerce journey.
Overview
The Universal Commerce Protocol (UCP) is an open-source standard developed by Google in collaboration with Shopify and other partners to standardize the full agentic commerce journey: discovery, consideration, purchase, order management, fulfillment, returns, and loyalty. It defines capability discovery and negotiation between agents and merchants and can compose with REST, MCP, AP2, and A2A. Note: an earlier draft referred to it as 'Universal Checkout Protocol'; the verified official name is 'Universal Commerce Protocol.' It is a Web2-oriented commerce standard.
