About Brazil CNPJ company registry

Brazil CNPJ company registry is an MCP server published by the GitHub account bnovarini. Brazil's open CNPJ registry: filter and count companies by sector, place, size, MEI, partners.

It is hosted by the publisher at one address, so there is nothing to install: your AI client connects to it over the internet.

It asks for no keys or passwords.

Version 0.1.0 was published on 8 October 2026, and the source code is public, so you can read it before installing.

Written from the registry entry. 7 automated checks on the registry entry and the live tool descriptions: 4 pass, 0 warn, 0 fail, 3 info. How we check.

What it asks for

This server declares no environment variables, so it asks for no keys or settings.
