## Description
**UCP Ready** transforms your WooCommerce store into an AI-agent-friendly commerce
platform by implementing the [Universal Commerce Protocol (UCP)](https://ucp.dev).
AI agents like Google’s shopping assistants, ChatGPT plugins, and custom MCP clients
can now:
* 🔍 **Discover** your store’s capabilities via a `.well-known/ucp` endpoint
* 📦 **Browse** your product catalog with AI-optimized metadata
* 🛒 **Create checkout sessions** with full shipping and discount support
* 🔐 **Authenticate** via OAuth 2.0 Identity Linking
* 💬 **Communicate** over REST, MCP (JSON-RPC), or Embedded Protocol bindings
#### Key Features
* **Multi-Transport Support** — REST API, MCP (Model Context Protocol), and Embedded
Protocol (EP) bindings
* **AI-Optimized Catalog** — Products are served with quick facts and FAQs designed
for agent consumption
* **OAuth 2.0 Identity Linking** — Agents can act on behalf of authenticated users
* **Shipping & Fulfillment** — Full integration with WooCommerce Shipping Zones
* **Discount Codes** — Agents can apply coupon codes during checkout
* **GDPR Compliance** — Buyer consent management built-in
* **Order Tracking** — Agents can query order status and fulfillment events
* **Bot Tracker** — Monitor AI agent traffic on your store
* **Built-in Simulator** — Test the full agent flow from your WordPress admin
#### Who Is This For?
* **Store owners** who want to be ready for the AI commerce revolution
* **Developers** building AI shopping agents or MCP clients
* **Agencies** deploying WooCommerce stores that need to be AI-discoverable
#### How It Works
1. Install and activate the plugin
2. Your store automatically exposes a UCP discovery endpoint at `/.well-known/ucp`
3. AI agents find your store, browse products, and create checkout sessions
4. Customers complete payment through your existing WooCommerce checkout
#### Links
* [UCP Specification](https://ucp.dev)
### External services
This plugin uses external JSON schemas from ucp.dev to define protocol responses.
*
What the service is: `ucp.dev` is the central repository for the Universal Commerce
Protocol schemas. The schema URLs are included in API responses so AI agents know
how to parse the data. * What data is sent and when: No personal, store, or customer
data is sent to `ucp.dev`. The service is acting strictly as a static schema host.*

## FAQ
### What is the Universal Commerce Protocol (UCP)?
UCP is an open protocol that enables AI agents to interact with online stores in
a standardized way. It defines how agents discover stores, browse catalogs, create
checkouts, and handle payments — all without screen scraping.
### Do I need to modify my products?
No! The plugin works with your existing WooCommerce products out of the box. You
can optionally add AI-optimized metadata (Quick Facts, FAQs) to enhance the agent
experience.
### Is this compatible with my payment gateway?
Yes. UCP creates standard WooCommerce orders. The customer completes payment through
your existing checkout flow, so any payment gateway that works with WooCommerce
will work with UCP.
### What is MCP (Model Context Protocol)?
MCP is a JSON-RPC based protocol that allows AI models to call tools. UCP Ready
exposes your store’s catalog and checkout as MCP tools that can be called by compatible
AI agents.
### Is the OAuth 2.0 flow secure?
Yes. The Identity Linking implementation follows RFC 6749 and RFC 8414 standards
with:
* Authorization codes that expire in 5 minutes * Token rotation on refresh*
Redirect URI validation * Proper token revocation (RFC 7009)
### Does this slow down my store?
No. The plugin only adds lightweight REST API endpoints and a small `` tag
to your HTML head. There is no impact on your storefront loading speed.
### What data is shared with AI agents?
Only publicly available product data (name, price, description, images) is shared
through the catalog API. Customer data is never exposed without explicit OAuth 2.0
authorization.
### Can I restrict which agents access my store?
Yes. You can set an API key in the plugin settings. Only agents with the correct
key can access the UCP endpoints.
