UCP Checker & Validator

UCP Checker & Validator is a free community tool for checking AI commerce readiness on e-commerce domains. It tests whether a store can be discovered and used by AI shopping agents, and it reports an AI Commerce Score for a domain or a client portfolio. The tool validates compliance with UCP and ACP, the open standards for AI-powered commerce from Google, Shopify, OpenAI, and Stripe.

Its checks go beyond basic JSON syntax. UCPtools says it runs four validation levels: structural checks for required fields and version format, UCP compliance rules such as namespace and origin binding, extension dependency chains, and HTTPS-only endpoints, network validation that fetches live schemas from ucp.dev, and agent simulation that tests the full discovery-to-checkout flow. The page also says it returns specific issues with exact fixes, rather than only a score. In its FAQ, it lists common validation errors including missing signing keys, payment handler misconfiguration, and namespace/origin mismatch.

The tool is presented for merchants, agencies, and developers. It mentions use across a store owner’s own site or a full client portfolio, and it offers step-by-step guides for major platforms including Shopify, WooCommerce, Magento, BigCommerce, Wix, and Squarespace. For CI workflows, it supports a published GitHub Action, the @ucptools/validator CLI, GitHub Actions, GitLab CI, CircleCI, and any runner via npx, with build failure based on a grade or score threshold and automatic pull request comments. UCPtools also provides related utilities and resources such as Generate UCP, AI Agent Test, Security Scan, Feed Analyzer, GDPR Generator, Schema Snippets, Guides, a blog, and a UCP spec link.

The site describes UCPtools as an independent community tool and says it is not affiliated with Google, Shopify, or the UCP consortium. It is available free to validate, with monitoring plans mentioned separately on the site.
