UCP status report
robotshop.com
robotshop.com publishes a valid UCP profile, but one thing in it breaks the spec: a UCP agent will ignore its Embedded service.

Problem
version
One entry is at a different version, so agents ignore it
version
This profile declares 2026-08-25, but dev.ucp.shopping (Embedded) is at 2026-04-08. The spec says every dev.ucp.* service, capability and extension must carry the profile's version, and an agent on 2026-08-25 must reject any entry that doesn't. Declare it at 2026-08-25, and describe older versions in a supported_versions profile. Not part of the UCP Score. How to fix →

Can UCP agents buy from robotshop.com?
Through its MCP service, an agent can search the catalogue, build a cart and start a checkout. The service answered our check. Its Embedded checkout is declared at an older version, so current agents ignore it. When an agent can't finish, it can hand the buyer a ready cart on the store's website. This is what the store declares and what our check reached; an observed agent run shows how far an agent actually gets.
Is robotshop.com ready for UCP agents?
robotshop.com publishes a valid UCP profile and scores 90/100 (grade A). 7 things to fix: one entry is at a different version, so agents ignore it, publish the public keys agents use to check your messages, publish Organization schema (JSON-LD) on the homepage and publish a /llms.txt brand brief.
What is a UCP profile?
The JSON file a store publishes at
/.well-known/ucp to tell UCP agents which services it offers, how to call them and how it takes payment. The spec calls it the business profile. robotshop.com's is 5.0 KB, written for UCP 2026-08-25. What goes in a UCP profile.How was robotshop.com checked?
With public requests on 18 Oct 2026: we read
/.well-known/ucp and robots.txt, validated the profile against UCP 2026-08-25, checked that its spec and schema links resolve, and called its MCP service. No sign-in and no purchase. How we check.
