I’ve been frustrated by how opaque agentic commerce is right now. Shopify and Google launched the Universal Commerce Protocol (UCP), but for a developer, it's often a black box in production. You might have your manifest at /.well-known/ucp, but is Gemini actually reading it? Or is it getting silently dropped by a legacy firewall rule?

I built this extension as a lightweight debugger for my own agentic workflows. It’s like Waze for UCP—as we browse, the community is crowdsourcing a map of agent-ready domains. We’ve verified 508 domains so far.

Key features for devs:

Zero-Click Workflow: Uses badge icons to show status instantly (Green = ready, Gray = not detected).

Instant Manifest Debugging: Surfaces HTTP status, response times, and version metadata for UCP manifests.

Gemini Readiness: Checks specifically if the Gemini agent (and others like GPTBot) can reach the store or if they are blocked by robots.txt/WAF rules.

Privacy-First: No tracking, no data selling, and minimal permissions (activeTab only).

You can try it out without an account or signup. I'd love to hear what other signals you'd want to see in the debugger, or if keeping it this lightweight is best!
