# UCP - Google's New Agent Protocol Source: https://www.youtube.com/watch?v=yDKpF6CjBUo Recap page: https://rapidrecap.app/video/yDKpF6CjBUo Generated: 2026-01-12T14:33:48.524+00:00 --- ## Quick Overview Google announced the Universal Commerce Protocol (UCP) at NRF 2024, an open-source agentic commerce protocol designed to standardize communication between consumer surfaces (like AI agents), businesses, payment providers, and identity providers, aiming to solve fragmentation and enable seamless, end-to-end shopping experiences directly within generative AI interfaces like ChatGPT and Google's AI Mode. **Key Points:** - Google introduced the Universal Commerce Protocol (UCP) as an open-source standard for agentic commerce. - UCP facilitates interoperability between consumer surfaces (AI agents), businesses, payment providers, and identity providers. - The protocol enables key capabilities including Product Discovery, Checkout (with AP2 extension), Order, and Identity Linking. - Demonstrations showed agents completing complex shopping tasks like finding a rug with specific criteria and executing instant checkout within ChatGPT and Google AI Mode. - UCP is co-developed and endorsed by major industry leaders including Shopify, Etsy, Wayfair, Target, and Walmart, along with over 20 others. - Google also announced Gemini Enterprise for Customer Experience, featuring specialized agents like Shopping Agent and Business Agent to leverage UCP. - The UCP roadmap prioritizes deeper support for the full consumer journey, including multi-item checkout, loyalty, and native cross-sell/upsell modules. ![Screenshot at 00:00: The initial slide visually outlines the Universal Commerce Protocol \(MCP/UCP\) as a standardized protocol connecting AI applications \(like chat interfaces, IDEs, and other AI apps\) on the left with data sources and tools \(like databases, development tools, and productivity tools\) on the right, illustrating the core concept of standardized communication.](https://ss.rapidrecap.app/screens/yDKpF6CjBUo/00-00-00.jpg) **Context:** The video discusses Google's major announcements at NRF 2024 regarding the future of AI-driven commerce, centered around the introduction of the Universal Commerce Protocol (UCP). This protocol serves as a standardized language to bridge the gap between various commerce entities—platforms, businesses, payment providers, and identity providers—which currently operate in fragmented ecosystems, making agentic commerce difficult. ## Detailed Analysis Google unveiled the Universal Commerce Protocol (UCP) at NRF 2024, positioning it as the 'common language for platforms, agents and businesses' to facilitate agentic commerce. UCP aims to solve the fragmentation in the commerce landscape by providing building blocks that allow diverse entities to interoperate through one standard without requiring custom builds. The protocol's primary goals include enabling Consumer Surfaces/Platforms to discover capabilities and facilitate purchases, allowing Businesses to expose inventory and retail logic in a standard way, and enabling Payment & Credential Providers to securely exchange tokens for transactions. Key capabilities highlighted in the architecture diagram include Product Discovery, Cart, Identity Linking, Checkout (with Agent Payment Protocol (AP2) extension), and Order, relying on underlying transports like Model Context Protocol (MCP) and Agent2Agent (A2A) Protocol. Demonstrations showcased agents using UCP to complete complex tasks, such as finding a specific rug with constraints and completing the purchase instantly within ChatGPT or Google's AI Mode, bypassing traditional browser redirects. Google is also launching Gemini Enterprise for Customer Experience, featuring specialized agents like the Shopping Agent and Business Agent. The Business Agent acts as a virtual sales associate, answering product questions in a brand's voice. The protocol's roadmap focuses on deeper support for the full consumer journey, including multi-item checkout, loyalty management, and native cross-sell/upsell modules. The UCP is already co-developed and endorsed by numerous industry leaders including Shopify, Etsy, Wayfair, Target, Walmart, and various payment providers like Stripe and Adyen. ### Introduction of UCP - UCP is an open standard designed to facilitate communication and interoperability between diverse commerce entities - Provides standardized common language and functional primitives - Goal is to enable seamless agentic commerce. ### UCP Architecture - Capabilities include Product Discovery, Cart, Identity Linking, Checkout (with AP2 extension), and Order, built upon underlying transports like MCP and A2A Protocol - Connects Consumer Surfaces with Business Backends. ### Agentic Commerce Demo - Agents successfully found products (rugs, suitcases) based on complex natural language queries and executed instant checkout across platforms like ChatGPT and Google AI Mode. ### Gemini Enterprise for Customer Experience - Introduces specialized agents like Shopping Agent, Customer Service Agent, Retail Search, and Merchandising Agent, leveraging UCP for end-to-end experiences. ### Industry Adoption - UCP was co-developed with and endorsed by industry leaders including Google, Shopify, Etsy, Wayfair, Target, Walmart, and over 20 others. ### UCP Roadmap Priorities - Focus on deeper support for the full consumer journey (multi-item checkout, loyalty, lifecycle management) and support for global markets. ![Screenshot at 00:00: Diagram showing the Universal Commerce Protocol \(MCP\) as a standardized hub connecting various AI applications \(left\) with data sources and tools \(right\).](https://ss.rapidrecap.app/screens/yDKpF6CjBUo/00-00-00.jpg) ![Screenshot at 00:04: Diagram illustrating Agent2Agent \(A2A\) protocol principles involving a Client Agent and Remote Agent, focusing on Secure Collaboration, Task Management, UX Negotiation, and Capability Discovery.](https://ss.rapidrecap.app/screens/yDKpF6CjBUo/00-00-04.jpg) ![Screenshot at 00:04: Diagram detailing the AI Agent acting as a mediator between the Merchant Ecosystem \(inventory, pricing\) and the Payments Ecosystem \(currency, credit cards\).](https://ss.rapidrecap.app/screens/yDKpF6CjBUo/00-00-04.jpg) ![Screenshot at 00:06: Visual representation of the AG-UI Protocol connecting 'Your Application' to various agent frameworks like LangGraph, LlamaIndex, and Microsoft Agent Framework.](https://ss.rapidrecap.app/screens/yDKpF6CjBUo/00-00-06.jpg) ![Screenshot at 01:37: High-level architecture diagram of the Universal Commerce Protocol showing capabilities like Product Discovery, Checkout, and Order connecting Consumer Surfaces and Business Backends via MCP and A2A Protocol.](https://ss.rapidrecap.app/screens/yDKpF6CjBUo/00-01-37.jpg)
