UCP solves a fundamental discovery problem: before it existed, AI agents had no standardized way to find out whether a WooCommerce store supported agent purchases, what products were available, or how to initiate checkout. Each agent platform built its own integration, and most stores had no integration at all. UCP creates one endpoint that every compatible agent — ChatGPT, Claude, Perplexity, Gemini — can query to discover the store and start a purchase flow.

The protocol supports three transport bindings. REST is the simplest — standard HTTP requests. MCP (Model Context Protocol) is the native agent communication layer that platforms like Anthropic and OpenAI use. Embedded Protocol handles inline purchase experiences where the agent completes the transaction within its own interface. Each binding gives the agent access to the same store capabilities: product browsing, inventory checks, shipping zone queries, discount code application, and checkout completion.

The built-in GDPR consent management is significant because agent purchases process personal data (name, address, payment details) without a browser consent banner — UCP handles this programmatically through its consent endpoints, so the merchant's privacy obligations are met regardless of the order channel (GDPR consent requirements for AI agent purchases). For WooCommerce stores, installing UCP is the first step to becoming visible to the growing ecosystem of AI shopping agents.
