vulnerable-mcp-servers-lab · Install

Each vulnerable server lives in its own directory with specific installation instructions. To use:

  1. Clone the repository: git clone https://github.com/appsecco/vulnerable-mcp-servers-lab.git
  2. Navigate to the specific vulnerable server directory (e.g., cd vulnerable-mcp-server-filesystem-workspace-actions)
  3. Follow the README instructions in that directory

For Claude Desktop integration, many servers include a claude_config.json snippet that should be merged into your Claude Desktop configuration. For example:

{
  "mcpServers": {
    "vulnerable-filesystem": {
      "command": "node",
      "args": ["index.js"]
    }
  }
}

NPX (recommended)

{
  "mcpServers": {
    "everything": {
      "command": "npx",
      "args": ["-y", "@modelcontextprotocol/server-everything"]
    }
  }
}

On Windows, use cmd /c:

{

    }
  }
}
