Problem
The profile isn't served with the caching the spec requires
Served with Cache-Control "max-age=14400". Spec level: MUST.
To fix
The profile has no ETag or Last-Modified header
Spec level: SHOULD.
To fix
Your store lives on www.fabricadehostias.com.br; fabricadehostias.com.br only redirects to it
How we decided: fabricadehostias.com.br forwards its homepage to www.fabricadehostias.com.br; your homepage names www.proigreja.com.br as its canonical address; and your UCP profile is served directly at www.fabricadehostias.com.br/.well-known/ucp. An agent given fabricadehostias.com.br instead gets a redirect, and the spec tells agents not to follow one, so it stops there. Serve /.well-known/ucp directly on fabricadehostias.com.br too if agents may use it.

Your UCP profile lists no public keys, so cryptographic message signing is not yet enabled for this store. HTTPS already confirms your store's identity; signing adds a further layer for checkout, payment and webhook messages.

Questions

Can UCP agents buy from fabricadehostias.com.br?
Through its MCP service, an agent can search the catalogue. This is what the store declares and what our check reached; an observed agent run shows how far an agent actually gets.
Is fabricadehostias.com.br ready for UCP agents?
fabricadehostias.com.br publishes a valid UCP profile and scores 80/100 (grade B). 4 things to fix: the profile isn't served with the caching the spec requires, the profile has no ETag or Last-Modified header, cryptographic message signing is not yet enabled and your store lives on www.fabricadehostias.com.br; fabricadehostias.com.br only redirects to it.
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. fabricadehostias.com.br's is 0.9 KB, written for UCP 2026-08-25. What goes in a UCP profile.
How was fabricadehostias.com.br checked?
With public requests on 7 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. No sign-in and no purchase. How we check.
