UCPJava is java implementation of ucp protocol. UCP is a new open standard / protocol for AI-driven shopping and commerce, announced by Google in January 2026. It’s designed to let AI agents (e.g., Google Gemini, Search-AI Mode, other assistants) interact with retailers, payment systems, identity systems, and backend commerce systems in a unified way — without requiring separate custom integrations for every agent, merchant, and platform.
