Google CEO Sundar Pichai appeared at the National Retail Federation conference to announce the Universal Commerce Protocol (UCP), an open standard designed to let AI agents discover products, manage shopping carts, and handle payments across e-commerce platforms. Sam Witteveen breaks down what UCP actually is and how it fits into Google’s growing stack of agent protocols — including MCP (tool access), A2A (agent-to-agent messaging), AP2 (payments), and AGUI (dynamic UIs).
UCP was co-developed with Shopify, Etsy, Target, Walmart, and Wayfair, with Amazon conspicuously absent. The protocol’s core value proposition is eliminating the fragmentation where every retailer currently needs custom integrations for every AI platform. Google has stated that UCP will power a new checkout feature inside AI Mode in Search and the Gemini app, giving retailers with existing Google Ads relationships a familiar on-ramp. Witteveen notes that Gemini’s rapid user growth (hundreds of millions of users in recent months) makes this an easy decision for most retailers.
Alongside UCP, Google announced “Business Agents” — brand-voice virtual sales associates that appear directly in search results — and a mechanism for retailers to surface direct offers inside AI Mode. Witteveen frames this as both a monetization play for Google’s AI search transition and a potential threat to startups building retail AI tooling, since Google is effectively commoditizing the business-agent layer.
