How the WooCommerce UCP checker works
Paste your store URL into our free UCP checker and it probes your live WooCommerce site the way an AI shopping agent would. It fetches your /.well-known/ucp discovery profile and validates it against the official Universal Commerce Protocol JSON Schemas, then checks the three files agents read before they shop: robots.txt for AI-agent access, llms.txt, and agents.md. You get a score from 0 to 100 and an A to F grade in seconds. It is open source, runs with no signup, and stores nothing.
What the WooCommerce UCP checker looks for
A valid UCP discovery profile
The backbone of the check. A missing or invalid /.well-known/ucp profile caps your score at 40, because without it agents cannot reliably discover your catalog, pricing or checkout. Most WooCommerce stores fail here: WooCommerce has no native UCP path, so nothing publishes this profile unless you add an integration layer.
AI-agent crawler access
Security plugins and CDN rules on WordPress often block GPTBot, OAI-SearchBot, PerplexityBot and Google-Extended without the owner realizing. The checker flags whether your robots.txt gives agents a clear, explicit policy.
llms.txt and agents.md
These optional files give language models a curated map of your store and carry agent-facing instructions. They are quick wins that most WooCommerce stores are missing.
Why most WooCommerce stores fail the UCP checker
Fewer than 5% of stores are AI-ready today, and WooCommerce stores are over-represented in that gap. Shopify implements UCP natively; WooCommerce does not. That means a stock WooCommerce store publishes no UCP profile at all and scores an F, no matter how good the products are. The fix is not a rebuild. The free UCPhub plugin publishes a valid, schema-conformant profile and keeps it on spec as UCP evolves, moving most stores from C or D to A within 24 hours.

WooCommerce UCP checker FAQ
Is the WooCommerce UCP checker free?
Yes. It is free forever, open source under Apache-2.0, and needs no signup. Nothing about your store is stored.
My store scored an F. What now?
That is expected for a stock WooCommerce store with no UCP profile. Install the free UCPhub plugin to publish a valid profile, then re-run the check. Most stores reach an A within a day.
Does the checker change anything on my store?
No. It only reads public files an AI agent would read. It makes no changes and stores no data.
Can I automate the check?
Yes. The open checker API at checker.ucphub.ai takes a POST with your store URL and returns the scored report as JSON, so you can run it from your terminal or CI pipeline.
