Is iris.metaztech.ai ready for UCP agents?
iris.metaztech.ai publishes a valid UCP profile and scores 81/100 (grade B). 3 things to fix: publish Organization schema (JSON-LD) on the homepage, publish a /llms.txt brand brief and cryptographic message signing is not yet enabled.
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. iris.metaztech.ai's is 1.5 KB, written for UCP 2026-08-25. What goes in a UCP profile.
How was iris.metaztech.ai checked?
With public requests on 1 Nov 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.
