METATRON Penetration Testing Assistant

Skill by ara.so — Daily 2026 Skills collection.

METATRON is a CLI-based AI penetration testing assistant that runs entirely locally — no cloud, no API keys. It orchestrates recon tools (nmap, whois, whatweb, curl, dig, nikto), feeds results to a locally running fine-tuned LLM (metatron-qwen via Ollama), and stores all findings in MariaDB with full scan history, vulnerability tracking, and PDF/HTML export.

Architecture Overview

metatron.py     ← CLI entry point, main menu, scan orchestration
db.py           ← MariaDB CRUD (history, vulns, fixes, exploits, summary)
tools.py        ← Recon tool runners (nmap, whois, whatweb, curl, dig, nikto)
llm.py          ← Ollama interface, agentic loop, AI tool dispatch
search.py       ← DuckDuckGo search + CVE lookup (no API key)
Modelfile       ← Custom metatron-qwen model config

Database spine: every scan creates a sl_no in history; all other tables link via sl_no.

Installation

1. Clone and set up Python environment

git clone https://github.com/sooryathejas/METATRON.git
cd METATRON
python3 -m venv venv
source venv/bin/activate
pip install -r requirements.txt

2. Install system recon tools

sudo apt install nmap whois whatweb curl dnsutils nikto

3. Install Ollama and pull base model

curl -fsSL https://ollama.com/install.sh | sh

# 8GB+ RAM:
ollama pull huihui_ai/qwen3.5-abliterated:9b

# <8GB RAM — use 4b and edit Modelfile FROM line accordingly:
ollama pull huihui_ai/qwen3.5-abliterated:4b

4. Build the custom metatron-qwen model

ollama create metatron-qwen -f Modelfile
ollama list   # verify metatron-qwen appears

Modelfile (the repo ships this — key parameters):

FROM huihui_ai/qwen3.5-abliterated:9b
PARAMETER num_ctx 16384
PARAMETER temperature 0.7
PARAMETER top_k 10
PARAMETER top_p 0.9

To use 4b instead, edit Modelfile:

FROM huihui_ai/qwen3.5-abliterated:4b

Then rebuild: ollama create metatron-qwen -f Modelfile

5. Set up MariaDB

sudo systemctl start mariadb
sudo systemctl enable mariadb
mysql -u root

CREATE DATABASE metatron;
CREATE USER 'metatron'@'localhost' IDENTIFIED BY '123';
GRANT ALL PRIVILEGES ON metatron.* TO 'metatron'@'localhost';
FLUSH PRIVILEGES;
EXIT;

Create all tables:

mysql -u metatron -p123 metatron < schema.sql

Or manually (paste from README schema block). The 5 tables:

  • history — one row per scan session (spine)
  • vulnerabilities — findings per session
  • fixes — remediation per vulnerability
  • exploits_attempted — exploit attempts per session
  • summary — raw scan + full AI analysis dump

Running METATRON

METATRON requires two terminals:

Terminal 1 — Load model into memory:

ollama run metatron-qwen
# Wait for >>> prompt before proceeding

Terminal 2 — Launch the assistant:

cd ~/METATRON
source venv/bin/activate
python metatron.py

Main Menu Flow

[1] New Scan      → enter target IP/domain → select tools → AI analyzes → saved to DB
[2] View History  → browse past scans → view/edit/delete/export
[3] Exit

New Scan — Tool Selection

[1] nmap
[2] whois
[3] whatweb
[4] curl headers
[5] dig DNS
[6] nikto
[a] Run all (except nikto)
[n] Run all + nikto (slow, thorough)

Exporting Reports

From View History → select scan → export:

  • PDF — professional vulnerability report
  • HTML — browser-viewable report

Common Patterns

Check if Ollama model is running before scan

import requests

def check_ollama_ready(model: str = "metatron-qwen") -> bool:
    try:
        resp = requests.get("http://localhost:11434/api/tags", timeout=5)
        models = [m["name"] for m in resp.json().get("models", [])]
        return any(model in m for m in models)
    except Exception:
        return False

if not check_ollama_ready():
    print("[!] metatron-qwen not found. Run: ollama run metatron-qwen")
    exit(1)

Query scan history

from db import get_db_connection

def get_full_scan_report(sl_no: int) -> dict:
    conn = get_db_connection()
    cursor = conn.cursor(dictionary=True)
    
    cursor.execute("SELECT * FROM history WHERE sl_no = %s", (sl_no,))
    history = cursor.fetchone()
    
    cursor.execute("SELECT * FROM vulnerabilities WHERE sl_no = %s", (sl_no,))
    vulns = cursor.fetchall()
    
    cursor.execute("SELECT * FROM summary WHERE sl_no = %s", (sl_no,))
    summary = cursor.fetchone()
    
    cursor.close()
    conn.close()
    
    return {"history": history, "vulnerabilities": vulns, "summary": summary}

Add a custom recon tool

# In tools.py — add your tool function:
def run_gobuster(target: str, wordlist: str = "/usr/share/wordlists/dirb/common.txt") -> str:
    result = subprocess.run(
        ["gobuster", "dir", "-u", f"http://{target}", "-w", wordlist],
        capture_output=True, text=True, timeout=180
    )
    return result.stdout

# Register it in the tool_map in run_selected_tools():
tool_map['gobuster'] = run_gobuster

Troubleshooting

metatron-qwen not found / connection refused

# Terminal 1: ensure model is loaded
ollama run metatron-qwen
# Should show >>> prompt

# Verify Ollama API is reachable
curl http://localhost:11434/api/tags

Out of memory when running 9b model

# Switch to 4b: edit Modelfile first line:
# FROM huihui_ai/qwen3.5-abliterated:4b
ollama create metatron-qwen -f Modelfile

MariaDB connection error

sudo systemctl status mariadb
sudo systemctl start mariadb

# Verify credentials work:
mysql -u metatron -p123 metatron -e "SHOW TABLES;"

mysql.connector not found

source venv/bin/activate
pip install mysql-connector-python

nmap requires root for SYN scan

sudo nmap -sV -sC -T4 <target>
# Or use TCP connect scan (no root needed):
nmap -sT -sV <target>

Nikto timeout

Nikto is slow by design. Either use [a] (all without nikto) or increase the subprocess timeout in tools.py:

result = subprocess.run(["nikto", "-h", target],
                        capture_output=True, text=True,
                        timeout=600)  # 10 minutes

Slow AI responses

The 9b model needs time to load. If response is slow after the first query, it's still loading. Subsequent queries will be faster. Ensure no other GPU/memory-heavy processes are running.

Configuration Reference

Setting Location Default Notes
DB host db.py localhost Change for remote DB
DB user db.py metatron Match SQL user created
DB password db.py 123 Change in production
DB name db.py metatron
Ollama URL llm.py http://localhost:11434
Model name llm.py metatron-qwen Must match ollama list
Context window Modelfile 16384 Increase for large scans
Temperature Modelfile 0.7 Lower = more deterministic

Security note: For production use, replace the hardcoded DB password with an environment variable: os.environ.get("METATRON_DB_PASSWORD", "123")
