- The Universal Commerce Protocol (UCP) is an open-source standard designed to enable seamless agentic commerce between consumers, businesses, and payment providers.
- UCP standardizes the commerce journey from discovery to order management, reducing integration complexity and technical barriers.
- Developed by Google in collaboration with industry leaders like Shopify, Etsy, and Walmart, UCP is endorsed by over 20 global partners.
- UCP supports multiple integration methods including APIs, Agent2Agent (A2A), and the Model Context Protocol (MCP).
- It features a unique payments architecture, separating payment instruments from handlers to support diverse payment providers.
- Businesses can dynamically expose capabilities like checkout and product discovery via standardized JSON manifests.
- A sample implementation demonstrates UCP's functionality, including checkout sessions and applying discounts.
- Google has built the first reference implementation of UCP to power purchases in conversational experiences like AI Mode in Search and Gemini.
- Businesses can participate in the Google implementation by having an active Merchant Center account and eligible products.
- UCP is open-source, inviting developers and businesses to contribute and shape the future of agentic commerce.
