About Tray

Tray stores publish a UCP profile on the merchant's own domain with an MCP service at /mcp-app/ucp. UCP Checker identifies Tray storefronts by that path and the platform's asset host, and measures what each store declares every 24 hours, on the same terms as every other platform.

Frequently Asked

About Tray on UCP Checker

How many Tray stores support UCP?
Tray has 154 verified Tray stores currently verified by UCP Checker. The leaderboard above shows the top 20 stores ranked by declared capability depth — the ones most likely to give an AI agent a complete end-to-end shopping experience.
How do I publish a UCP profile on Tray?
Publishing a UCP profile on Tray means serving a valid JSON document at /.well-known/ucp on your store's origin domain. Depending on your stack this can be handled via a custom app, a platform-level feature (where available), or by proxying the endpoint through your CDN. Once published, our crawler will auto-detect it on the next 24h cycle.
How often is the Tray list updated?
We re-crawl every known Tray storefront at least every 24 hours and re-check any store you manually trigger a fresh check on. The counts, leaderboard, and capability coverage on this page update automatically — the data you're looking at is never more than a day old.
Can I add my Tray store to UCP Checker?
Yes — just run a live check on your domain. If you publish a valid UCP profile at /.well-known/ucp you'll appear on this page automatically on the next crawl cycle. No signup, no fee, no gatekeeping.
