Cpfhub

Overview

Cpfhub is an MCP server that connects AI agents directly to CPFHub.io, letting you query Brazilian CPF data without leaving your workflow. Rather than switching between applications, your AI assistant can call Cpfhub as a native tool, making CPF lookups seamless and immediate.

The server runs locally through the npm package @cpfhub/mcp, communicating via stdio on your machine. You'll need a CPFHUB_API_KEY environment variable to authenticate. Install it with npx -y @cpfhub/mcp. The latest release is v1.0.1, and the source code lives at cpfhub/cpfhub-mcp on GitHub.

Cpfhub belongs in the AI & Agents category on mcp.site and works with all major MCP clients including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, and Zed. If you maintain this server, claim your listing to earn the Verified badge and keep information up to date.
