Radare2 snap and docker repository

This repository contains the recipie to build the snap version of radare2 using docker as well to build a standalone docker image with the same build.

The resulting build includes the following projects:

• radare2
• r2ghidra
• r2frida (only in supported platforms)
• r2dec
• r2yara
• r2ai
• r2mcp
• r2book (as info file)

Install the snap

Radare requires snap classic confinement, to install run:

sudo snap install radare2 --classic

Once installed all radare commands are available as: radare2.<command> (ex: radare2.rasm2).

Configure CLI aliases

To allow using radare commands without this prefix, it can be solved by using shell aliases. So as an example could be something like this:

alias r2='radare2.r2'
alias r2agent='radare2.r2agent'
alias r2frida-compile='radare2.r2frida-compile'
alias r2mcp='radare2.r2mcp'
alias r2p='radare2.r2p'
alias r2pm='radare2.r2pm'
alias r2r='radare2.r2r'
alias r2sdb='radare2.r2sdb'
alias rabin2='radare2.rabin2'
alias radiff2='radare2.radiff2'
alias rafind2='radare2.rafind2'
alias rafs2='radare2.rafs2'
alias ragg2='radare2.ragg2'
alias rahash2='radare2.rahash2'
alias rapatch2='radare2.rapatch2'
alias rarun2='radare2.rarun2'
alias rasign2='radare2.rasign2'
alias rasm2='radare2.rasm2'
alias ravc2='radare2.ravc2'
alias rax2='radare2.rax2'
alias sleighc='radare2.sleighc'
alias yara='radare2.yara'
alias yarac='radare2.yarac'
alias clang-format-radare2='radare2.clang-format-radare2'

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:

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

2. Add the following to your configuration file:

{
  "mcpServers": {
    "radare2": {
      "command": "radare2.r2mcp"
    }
  }
}

VS Code Integration

To use r2mcp with GitHub Copilot Chat in Visual Studio Code by adding it to your user configuration (see also add an mcp server to vscode):

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": "radare2.r2mcp"
    }
  },
  "inputs": []
}

Zed Integration

You can use r2mcp with Zed as well by adding it to your configuration:

1. Open the command palette: CMD + Shift + P (macOS) or Ctrl + Shift + P (Windows/Linux).1º
2. Search of agent: open configuration or search of settings.
3. Add your server as such:

  "context_servers": {
    "r2-mcp-server": {
      "source": "custom",
      "command": "radare2.r2mcp"
    }
  }

Note: you will need another LLM agent, such as Claude, Gemini or else to be able to use it.

The docker image

As explained, with the same snap build a docker image is generated.

For documentation on how to use this docker image you can refer to containers section in this respository.
