Overview

AI-generated overview

Remote MCP server giving assistants Brazilian B2B buying signals and company data by CNPJ, plus rural property checks by CAR code.

What you can do
  • Look up Brazilian company data by CNPJ.
  • Retrieve B2B buying signals for prospecting and sales research.
  • Check rural properties by CAR code.
  • No tool list is published, so exact operations are not documented; the description only names these data areas.
When to use it
Useful when an assistant needs Brazilian company or rural property information, for example qualifying B2B leads, enriching records by CNPJ, or verifying a rural property by its CAR code.
Requirements
A remote MCP endpoint at captario.com.br over streamable HTTP. OAuth authentication is required, so a Captário account or authorization is needed. No environment variables or headers are declared.
Before you install
Access is tied to an OAuth authorization, so review which account and scopes you grant. Queries send CNPJ and CAR identifiers to a third-party Brazilian service; check its terms and data-handling before use. Tool behavior and any write actions are undocumented.

Installation

In SourceWeft

  1. Open Captário 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.com.captario%2Fcaptario/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.

Tools

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.
