Radare2 MCP Server

A MCP server for using radare2 with AI assistants like Claude.

Features

This implementation provides a simple MCP server that:

• Uses a direct stdin/stdout communication model
• Provides basic tool capabilities
• Allows seamless binary analysis with radare2
• Direct integration of radare2 with AI assistants
• File exploration and inspection

Installation

The simplest way to install the package is by using r2pm:

$ r2pm -Uci r2mcp

The r2mcp executable will be copied into the r2pm's bindir in your home, but this binary is not suposed to be executed from the shell because it will only work when launched from the MCP service handler of your language model of choice.
