Overview

AI-generated overview

Lets an assistant look up Brazilian companies by CNPJ, covering registry data, sanctions, federal contracts and CVM records with sources.

What it does
This remote MCP server performs due diligence on Brazilian companies identified by their CNPJ number. According to its description, it returns company registry information along with sanctions checks, federal contract records and CVM data, and it cites the sources behind each result. The manifest does not list individual tool names, so the exact call structure is not documented here.
When to use it
Useful when an assistant needs to verify a Brazilian counterparty, supplier or partner before a deal, or to gather public compliance and contract information about a company. It fits due diligence, onboarding and research workflows that start from a CNPJ.
Requirements
A remote streamable HTTP endpoint; nothing is installed locally. It requires an Authorization header carrying a Bearer API key obtained from the provider's page, and network access to the endpoint. The free plan is stated as 100 calls per month.
Before you install
The Authorization header carries a secret API key; keep it out of logs and shared transcripts. Queries send the CNPJ you look up to a third-party service, and results are only as current as that service's sources. Verify important findings against the cited sources before relying on them.
