UCPReady implements the Universal Commerce Protocol (UCP) on your WooCommerce store. Once installed, any UCP-compatible AI agent can find your store, search your catalog, and place orders on behalf of your customers — fully autonomously.
What it does:
Your store gets a discovery endpoint at /.well-known/ucp that AI platforms use to understand what your store sells and how to transact with it. From there, agents can search products, build a checkout session, apply fulfillment and payment options, and complete an order — all via structured API calls without any human clicking through a browser.
What’s included in the free version:
- UCP discovery manifest (
/.well-known/ucp) with capability negotiation - REST API — full checkout lifecycle: create, update, complete, cancel
- MCP transport — JSON-RPC 2.0, compatible with Claude, ChatGPT, and any MCP host
- Embedded Checkout — iframe protocol with postMessage delegation
- OAuth 2.0 identity linking — agents pre-fill buyer details from customer accounts
- Wallet payment support (Terrawallet store credit)
- AI revenue analytics dashboard — see which agents are driving orders
- Idempotency store — duplicate order protection
- Webhook signing — Ed25519 detached JWT (RFC 7797)
- Tested on stores with 40,000+ SKUs
