Why it matters, and how to fix it

Why AI agents care

UCP is the open standard from Google and Shopify that lets AI agents search your catalog, build a cart and check out directly, in Google AI Mode, Gemini and other agents.

The fix

  • Any platform: Publish a UCP business profile at /.well-known/ucp that points agents to your catalog, cart and checkout endpoints.
  • Shopify: Shopify serves UCP for online stores automatically. If your domain runs a custom (headless) front end, forward /.well-known/ucp to your myshopify.com domain.
  • WooCommerce: WooCommerce has no built-in UCP support yet. A UCP plugin or custom endpoint is needed.

How we measured

  • Every store on our public benchmark lists got the same audit as AgentReady's free check. This page counts one of its 16 checks across all of them.
  • 109 of 113 stores returned a result for this check; 4 could not be checked and are left out of every number above.
  • Audits ran from our servers in Singapore. Real AI agents visit from their companies' own networks, so firewall results are a strong signal, not proof.
  • Lists are chosen by hand and refreshed monthly. Last run October 11, 2026.
  • Run one of these stores and want it removed or re-checked? Email dev.prathapk@gmail.com.
