Questions before you start.
What is free, which tool fits your storefront, and where to begin.
Yes. The AI Agent Score Scan is a one-time free simulation with no credit card. The UCP Validator and UCP Playground are free to use on any storefront. Ongoing optimization after the scan follows the pricing on /pricing.
No. The UCP Validator works without signing in. The UCP Playground gives anonymous visitors a limited number of free messages; create an account for unlimited sessions against your own connected store.
The Validator checks whether a store publishes a valid /.well-known/ucp profile and whether agents can reach it. The Playground goes further: it drives a live AI shopping agent through catalog search, cart, and checkout against that store so you can see real tool calls and responses.
Start with the free Scan if you have a Shopify or WooCommerce catalog. If you are evaluating protocol readiness first, run the UCP Validator on your domain, then read How it works for the full simulate → diagnose → optimize loop.
