Google announced major updates to the Universal Commerce Protocol, adding Cart, Catalog, and Identity Linking capabilities that enable AI agents to shop more like humans. The open standard, developed with Walmart, Target, and other major retailers, aims to bridge the gap between AI-powered product discovery and actual purchase completion across the web.

Google Expands Universal Commerce Protocol Capabilities

Google has unveiled significant updates to the Universal Commerce Protocol (UCP), introducing three new capabilities designed to help AI agents replicate human shopping behaviors more effectively

New Features Bridge the Gap for AI-Powered Shopping Experiences

The Catalog capability represents another major enhancement, enabling AI agents to retrieve real-time product details from a merchant catalog when necessary, including variants, inventory levels, and pricing information

2

. Perhaps most significantly for customer retention, the Identity Linking feature allows shoppers on UCP-integrated platforms to access the same loyalty benefits and member perks they would receive when logged into a retailer's site directly, such as special pricing or free shipping

2

. This functionality aims to make shopping more connected across the web, addressing a critical pain point in agentic commerce.

Simplified Onboarding Process Targets Retailers of All Sizes

Google is actively working to simplify online shopping by streamlining the onboarding process for retailers through Google's Merchant Center, with the rollout planned over the coming months

Open Standard Developed with Major Retail Partners

The Universal Commerce Protocol was initially developed as an open standard in partnership with Walmart, Target, Shopify, Etsy, and Wayfair

2

. The protocol moves away from relying on one-off integrations between AI agents and merchants, establishing a standardized approach for handling product discovery, checkout, and post-purchase support

2

. Merchants can expose inventory, pricing, and fulfillment logic through the protocol, allowing agents to complete purchases without redirecting users to external sites.

Integration Across Google's AI Ecosystem

Google plans to integrate relevant UCP capabilities into shopping experiences within AI Mode in Google Search, the Gemini app, and other platforms

1

. This integration positions Google to leverage its AI infrastructure for commerce applications, though questions remain about execution. According to PYMNTS CEO Karen Webster, while AI models excel at helping consumers research and shortlist options, the infrastructure needed to curate available options and complete purchases represents a significant gap

2

. She characterized current agentic commerce as "mostly a highly intelligent search bar" that ultimately hands consumers off to complete transactions elsewhere

Industry Implications and Future Outlook

The updates signal Google's commitment to building infrastructure that addresses the current limitations of agentic commerce. As UCP adopters can customize their experience by selecting which capabilities to support, the flexibility may encourage broader adoption across diverse retail segments

1

. The protocol's success will depend on whether it can truly close the gap between AI-assisted product discovery and seamless transaction completion, transforming what is currently an advanced search tool into a fully functional commerce platform.
