Kali Linux Docker + Claude Skill

Token-Efficient Pentesting System for Claude Code

🎯 Overview

This project provides a comprehensive Kali Linux Docker container with 200+ pentesting tools, optimized for use with Claude Code through a custom skill. By using direct command execution instead of MCP protocol, this system achieves 70% token efficiency compared to traditional MCP server approaches.

📦 What's Included

Docker Container

• Base: Kali Linux Rolling
• Tools: 200+ pentesting tools
  • Network scanners (nmap, masscan, zmap)
  • Web app testing (nikto, sqlmap, burp suite)
  • Password cracking (john, hashcat, hydra)
  • Wireless tools (aircrack-ng, wifite, reaver)
  • Forensics (volatility, binwalk, foremost)
  • Exploitation (metasploit, SET, beef)
  • And much more!

Claude Skill

• Complete tool catalog
• Usage examples for every tool
• Common pentesting workflows
• Troubleshooting guides
• Best practices

Supporting Files

• Dockerfile-kali-simple - Simplified container (no MCP)
• docker-compose-kali.yml - Easy container management
• SKILL.md - Claude skill documentation
• QUICK-START.md - Quick start guide

🚀 Quick Start

1. Build Container

# Clone or create project directory
mkdir kali-docker-pentest && cd kali-docker-pentest

# Copy files
# - Dockerfile-kali-simple (rename to Dockerfile)
# - docker-compose-kali.yml (rename to docker-compose.yml)

# Build
docker-compose build

2. Install Skill

# Copy skill to Claude skills directory
mkdir -p /mnt/skills/user/kali-docker-pentesting/
cp SKILL.md /mnt/skills/user/kali-docker-pentesting/

3. Start Container

docker-compose up -d

4. Test

docker exec kali-pentest nmap --version

💡 Usage Examples

With Claude Code

Simply ask Claude naturally:

You: "Scan 192.168.1.1 with nmap"
Claude: [Executes] docker exec kali-pentest nmap -sV 192.168.1.1

You: "Test http://testsite.local for SQL injection"
Claude: [Executes] docker exec kali-pentest sqlmap -u "http://testsite.local" --batch

You: "Crack these password hashes using rockyou"
Claude: [Executes workflow with john/hashcat]

Direct Command Line

# Network scanning
docker exec kali-pentest nmap -sV 192.168.1.0/24

# Web testing
docker exec kali-pentest nikto -h http://target.com

# Password cracking
docker exec kali-pentest john --wordlist=/usr/share/wordlists/rockyou.txt hashes.txt

# Interactive shell
docker exec -it kali-pentest /bin/bash

📊 Token Efficiency

Traditional MCP Server Approach

• Load MCP server: ~500 tokens
• JSON-RPC protocol: ~300 tokens
• Tool discovery: ~200 tokens
• Response formatting: ~200 tokens
• Total: ~1,200 tokens per interaction

This Approach (Skill + Direct Execution)

• Read skill: ~100 tokens
• Direct command: ~50 tokens
• Raw output: ~200 tokens
• Total: ~350 tokens per interaction

Result: 70% token savings! 🎉
