Overview

AI-generated overview

A remote MCP server that lets an assistant vet a Brazilian company by CNPJ, combining official registry data with its Reclame Aqui reputation.

What you can do
Look up a Brazilian company by its CNPJ number and return official registry data for it, such as registration details held in the national company registry. Retrieve the company's Reclame Aqui reputation alongside the registry record, so the two views can be compared in one step. Support due-diligence checks on a Brazilian counterparty before a deal, contract or partnership.
When to use it
Useful when you need a quick background check on a Brazilian company identified by CNPJ, for example before onboarding a supplier, signing a contract or assessing customer complaints and reputation.
Requirements
A remote MCP endpoint reached over streamable HTTP; no local package or runtime is needed. Authentication is required via OAuth. Network access to the hosted endpoint is needed.
Before you install
The server requires OAuth sign-in, so an account and its authorization are involved. Lookups concern real companies and their public reputation, so results should be treated as reference material rather than a final compliance decision.

Installation

In SourceWeft

  1. Open Brazil Due Diligence — CNPJ Registry + Reclame Aqui in the dashboard and add it to a workspace.
  2. Connect the required credentials. They are stored privately and never shown on public pages.
  3. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.paulovitorti%2Fbrazil-company-due-diligence/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config. The client completes OAuth sign-in on first connect.

This server asks you to sign in, so SourceWeft could not read its tools without an account and has not indexed them. What a connected account sees can depend on that account and its permissions.

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
