Radare2 MCP Server

An MCP server for using radare2 with AI assistants such as Claude, VSCode, CLION, Mai, OpenCode, ...

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
• Integrates radare2 directly with AI assistants
• Enables file exploration and inspection

Installation

Using r2pm

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

$ r2pm -Uci r2mcp

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

$ r2pm -r mcp

Using Docker

Alternatively, you can build the Docker image:

docker build -t r2mcp .

Update your MCP client configuration file (see below) to use the Docker image to use:

• "command": "docker"
• "args": ["run", "--rm", "-i", "-v", "/tmp/data:/data", "r2mcp"].

Configuration

Claude Desktop Integration

In the Claude Desktop app, press CMD + , to open the Developer settings. Edit the configuration file and restart the client after editing the JSON file as explained below:

1. Locate your Claude Desktop configuration file:

   • macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
   • Windows: %APPDATA%\Claude\claude_desktop_config.json
   • Linux: ~/.config/Claude/claude_desktop_config.json

2. Add the following to your configuration file:

{
  "mcpServers": {
    "radare2": {
      "command": "r2pm",
      "args": ["-r", "r2mcp"]
    }
  }
}

VS Code Integration

To use r2mcp with GitHub Copilot Chat in Visual Studio Code by adding it to your user configuration (see other options here):

1. Open the Command Palette with CMD + Shift + P (macOS) or Ctrl + Shift + P (Windows/Linux).
2. Search for and select Copilot: Open User Configuration (typically found in ~/Library/Application Support/Code/User/mcp.json in macOS).
3. Add the following to your configuration file:

{
  "servers": {
    "radare2": {
      "type": "stdio",
      "command": "r2pm",
      "args": ["-r", "r2mcp"]
    }
  },
  "inputs": []
}

For Developers

Build from Source

To test the server locally, you can build and install it with make:

make install

This will compile the server and place the r2mcp binary in /usr/local/bin on macOS.

You can now add the following configuration to your VS Code mcp.json as explained above:

{
  "servers": {
    "r2mcp": {
      "type": "stdio",
      "command": "r2mcp",
      "args": []
    }
  },
  "inputs": []
}

Tip: So that the client doesn't get confused, it's best to enable one server at a time. You can do this by commenting out the other server in the configuration file.
