Overview

AI-generated overview

Remote MCP server for querying Brazil's official registry of active companies, CNAE activity codes, partners and B2B contacts.

What you can do
  • Look up active companies in the Brazilian federal tax registry (Receita Federal) and their details.
  • Search CNAE activity codes to find or filter companies by sector.
  • Retrieve company partners (sócios) and B2B contact information.
  • No individual tool list is published, so exact operations are not documented.
When to use it
Useful when an assistant needs Brazilian company data: prospecting, supplier or partner checks, sector research by CNAE, or enriching B2B contact lists from official registry records.
Requirements
A remote streamable HTTP endpoint at dados.anotae.app.br; no local package or runtime. OAuth authentication is required, so the user must sign in with the provider's account. No environment variables or headers are declared.
Before you install
Access requires OAuth sign-in to a third-party service, which will see the queries made. Results concern real companies and individuals (partners, contacts), so handle personal data according to privacy rules. The tool list is not published; confirm what data is returned and whether any usage limits or costs apply before relying on it.

Installation

In SourceWeft

  1. Open Receita Federal do Brasil (Anotaê Dados Abertos) 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/br.app.anotae.dados%2Fmcp/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.

Score

60% of the applicable checks met

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.
