Discovery
Problem
The profile sits behind a redirect
/.well-known/ucp
autorizadapecas.com.br/.well-known/ucp answers 301 redirect. The spec forbids redirects on the profile, so an agent that asks autorizadapecas.com.br stops there. Serve it directly on every host agents use. How to fix →

Questions

Can UCP agents buy from autorizadapecas.com.br?
Through its MCP service, an agent can search the catalogue. The service answered our check. But the profile is only served after a redirect from autorizadapecas.com.br, and the spec forbids that, so an agent that follows the rules stops before it starts. This is what the store declares and what our check reached; an observed agent run shows how far an agent actually gets.
Is autorizadapecas.com.br ready for UCP agents?
autorizadapecas.com.br publishes a valid UCP profile and scores 82/100 (grade B). 6 things to fix: the profile sits behind a redirect, the profile isn't served with the caching the spec requires, the profile has no ETag or Last-Modified header and publish the public keys agents use to check your messages.
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. autorizadapecas.com.br's is 0.8 KB, written for UCP 2026-04-08. What goes in a UCP profile.
How was autorizadapecas.com.br checked?
With public requests on 22 Oct 2026: we read /.well-known/ucp and robots.txt, validated the profile against UCP 2026-04-08, checked that its spec and schema links resolve, and called its MCP service. No sign-in and no purchase. How we check.
