Google Updates Universal Commerce Protocol to Expand AI Agent Shopping Capabilities
Google launched the Universal Commerce Protocol, or UCP, in January 2026, working with retailers including Shopify and Walmart to create an open standard for communication between AI agents and merchants’ systems. The protocol covers product searches, ordering and payments, and is intended to reduce platform integration costs and drive broader adoption of agentic shopping.
As of July 20, 2026, Google had added shopping-cart and product-catalog features to UCP, allowing AI agents to add or remove multiple items and check prices and inventory in real time. An identity-linking feature also allows users to retain merchant loyalty discounts and free-shipping benefits. Google had not disclosed transaction values or the number of merchants that had launched the protocol.
