Quick context: UCP was announced Jan 11, 2026 by Google, Shopify, and 25+ partners. It's an open standard that lets AI shopping agents discover and interact with e-commerce stores.
I built UCPtools because:
1. There was no easy way to validate UCP profiles
2. Merchants had no visibility into AI agent traffic to their stores
3. No monitoring existed for when profiles break
The free validator is unlimited - paste any URL, get instant results.
The paid tier ($9/mo) adds AI Agent Analytics - you can see exactly which AI agents (Gemini, Perplexity, Claude) are visiting your store, what they're doing, and get alerted if something breaks.
The spec is genuinely open (ucp.dev) - anyone can implement it without being a partner. Just publish a JSON file at /.well-known/ucp.
Built a free validator at ucptools.dev to check implementations.
Tested several "partner" sites and almost no one has deployed it yet, including google.com (returns 404). The 60+ endorsements are just that - endorsements, not implementations.
If anyone wants to test their implementation, I built a free validator:
ucptools.dev
Checks version format, service bindings, capabilities, namespace rules,
signing keys (for Order capability), etc. Shows exactly which fields
are missing or malformed.
Built a free validator for this at ucptools.dev - checks /.well-known/ucp
compliance against the spec and gives A-F grading with specific fix
recommendations.
Interesting finding: tested major retailers and even google.com returns
404 on their UCP endpoint. Early days.
Also made an Apify Actor for bulk validation if anyone needs to check
multiple domains programmatically.

Curious what HN thinks - is AI commerce going to be a real thing, or overhyped? Would love feedback on the tools!
