See agentic readiness on every store you visit
Free Chrome extension that detects UCP manifests as you browse. Capabilities, payment handlers, transports, AI bot policies, and spec version — all in one click. No account required.
UCP
Instant Detection
Automatically probes /.well-known/ucp on every storefront. Capabilities, payment handlers, transports, and spec version revealed in milliseconds.
AI Bot Visibility
See exactly which AI agents can reach the store: GPTBot, Google-Extended, ClaudeBot, Apple Intelligence, and CCBot — with the live robots.txt verdict.
Zero-Click Workflow
Green dot = UCP ready. Gray dot = not detected. View Status, Run Check, or Open Playground — all from the popup, without leaving your tab.
Privacy First
Path-scoped permissions only access /.well-known/ucp. No cookies, browsing history, or page content is ever read, stored, or transmitted.
Who uses the extension?
Three audiences get the most value out of having UCP visibility one click away.
E-commerce Agencies
Verify UCP compliance on client stores without opening DevTools. See capabilities, payment methods, and transports at a glance during audits.
AI Platform Teams
Confirm MCP endpoints, capabilities, and spec versions before integration. Launch a Playground session to test agent interactions live.
Growth & BD Teams
Spot agent-ready brands while browsing. Send prospects their public UCP status report as a high-signal conversation starter.

The optional "Share anonymous uptime stats" toggle (on by default) sends only public manifest data to help keep the global directory current. Requests use credentials: "omit" so no session data ever leaves your browser.
