DadosBR

DadosBR MCP Server delivers a focused Brazilian OSINT toolkit as an MCP server, exposing 23 tools that query government transparency, legal, company, financial, health, and intelligence data through a unified MCP interface. It enables you to perform structured, multi-source investigations with ease from any MCP-compatible client.
