MCP Kali Server

Kali MCP Server is a lightweight API bridge that connects MCP Clients (e.g: Claude Desktop, 5ire) to the API server which allows excuting commands on a Linux terminal.

This allows the MCP to run terminal commands like nmap, nxc or any other tool, interact with web applications using tools like curl, wget, gobuster. And perform AI-assisted penetration testing, solving CTF web challenge in real time, helping in solving machines from HTB or THM.

👉 How MCP is Revolutionizing Offensive Security

🔍 Use Case

The goal is to enable AI-driven offensive security testing by:

• Letting the MCP interact with AI endpoints like OpenAI, Claude, DeepSeek, or any other models.
• Exposing an API to execute commands on a Kali machine.
• Using AI to suggest and run terminal commands to solve CTF challenges or automate recon/exploitation tasks.
• Allowing MCP apps to send custom requests (e.g., curl, nmap, ffuf, etc.) and receive structured outputs.

Here are some example for my testing (I used google's AI gemini 2.0 flash)

🛠️ Installation and Running

On your Kali Machine

git clone https://github.com/Wh0am123/MCP-Kali-Server.git
cd MCP-Kali-Server
pip install -r requirements.txt
python3 kali_server.py

Command Line Options:

• --ip <address>: Specify the IP address to bind the server to (default: 127.0.0.1 for localhost only)
  • Use 127.0.0.1 for local connections only (secure, recommended)
  • Use 0.0.0.0 to allow connections from any network interface (very dangerous; use with caution)
  • Use a specific IP address to bind to a particular network interface
• --port <port>: Specify the port number (default: 5000)
• --debug: Enable debug mode for verbose logging

Examples:

# Run on localhost only (secure, default)
python3 kali_server.py

# Run on all interfaces (less secure, useful for remote access)
python3 kali_server.py --ip 0.0.0.0

# Run on a specific IP and custom port
python3 kali_server.py --ip 192.168.1.100 --port 8080

# Run with debug mode
python3 kali_server.py --debug

On your MCP client machine (can be local or remote)

git clone https://github.com/Wh0am123/MCP-Kali-Server.git
cd MCP-Kali-Server
pip install -r requirements.txt

If you're running the client and server on the same machine:

./mcp_server.py --server http://127.0.0.1:5000

If separate machines, create an ssh tunnel to your Kali MCP server, then launch the client:

ssh -L 5000:localhost:5000 user@KALI_IP
./mcp_server.py --server http://127.0.0.1:5000

NOTE: If you're openly hosting the Kali MCP server on your network (kali_server --IP...), you don't need the SSH tunnel ⚠️(this is highly discouraged)⚠️.

./mcp_server.py --server http://LINUX_IP:5000

Configuration for claude desktop:

edit (C:\Users\USERNAME\AppData\Roaming\Claude\claude_desktop_config.json)

{
    "mcpServers": {
        "kali_mcp": {
            "command": "python3",
            "args": [
                "/absolute/path/to/mcp_server.py",
                "--server",
                "http://LINUX_IP:5000/"
            ]
        }
    }
}

Configuration for 5ire Desktop Application:

• Simply add an MCP with the command python3 /absolute/path/to/mcp_server.py http://LINUX_IP:5000 and it will automatically generate the needed configuration files.

🔮 Other Possibilities

There are more possibilites than described since the AI model can now execute commands on the terminal. Here are some example:

• Memory forensics using Volatility

  • Automating memory analysis tasks such as process enumeration, DLL injection checks, and registry extraction from memory dumps.

• Disk forensics with SleuthKit

  • Automating analysis from disk images, timeline generation, file carving, and hash comparisons.
