External Linters (optional):

MEDUSA auto-detects bandit, eslint, shellcheck, etc. if installed
See Optional Tools Guide for installation instructions

🚀 Quick Start

Installation

# Install MEDUSA (works on Windows, macOS, Linux)
pip install medusa-security

# Run your first scan - that's it!
medusa scan .

Virtual Environment (Recommended):

# Create and activate virtual environment
python3 -m venv medusa-env
source medusa-env/bin/activate  # On Windows: medusa-env\Scripts\activate

# Install and scan
pip install medusa-security
medusa scan .

Platform Notes:

Windows: Use py -m medusa if medusa command is not found
macOS/Linux: Should work out of the box

Optional: AI Model Scanning

# Install modelscan for ML model vulnerability detection
medusa install --ai-tools

Optional: External Linters

MEDUSA auto-detects external linters if installed (bandit, eslint, shellcheck, etc.) and uses them automatically to enhance scan coverage.

See Installation Guide → for platform-specific instructions.

Note: External linters are optional. MEDUSA's 4,000+ built-in rules work without them. For installation support, please refer to each tool vendor's documentation.

MEDUSA uses a YAML configuration file for project-specific settings:

# MEDUSA Configuration File
version: 2026.3.0

# Scanner control
scanners:
  enabled: []      # Empty = all scanners enabled
  disabled: []     # List scanners to disable

# Build failure settings
fail_on: high      # critical | high | medium | low

# Exclusion patterns
exclude:
  paths:
    - node_modules/
    - venv/
    - .venv/
    - .git/
    - __pycache__/
    - dist/
    - build/
  files:
    - "*.min.js"
    - "*.min.css"

# IDE integration
ide:
  claude_code:
    enabled: true
    auto_scan: true
  cursor:
    enabled: false
  vscode:
    enabled: false

# Scan settings
workers: null        # null = auto-detect CPU cores
cache_enabled: true  # Enable file caching for speed

Generate Default Config

medusa init

This creates .medusa.yml with sensible defaults and auto-detects your IDE.

🤖 IDE Integration

MEDUSA supports 5 major AI coding assistants with native integrations. Initialize with medusa init --ide all or select specific platforms.

Usage:

gemini /scan              # Full scan
gemini /scan --quick      # Quick scan
gemini /install --check   # Check tools

OpenAI Codex

What it creates:

AGENTS.md - Project context (root level)

Usage:

Ask: "Run a security scan"
Codex: *executes medusa scan .*

GitHub Copilot

What it creates:

.github/copilot-instructions.md - Security standards and best practices

How it helps:

Knows project security standards
Suggests secure code patterns
Recommends running scans after changes
Helps fix security issues

Cursor

What it creates:

.cursor/mcp-config.json - MCP server configuration
Reuses .claude/ structure (Cursor is VS Code fork)

Usage:

Works like Claude Code integration
MCP-native for future deeper integration

🔧 Advanced Features

System Load Monitoring

MEDUSA automatically monitors system load and adjusts worker count:

# Auto-detects optimal workers based on:
# - CPU usage
# - Memory usage
# - Load average
# - Available cores

# Warns when system is overloaded:
⚠️  High CPU usage: 85.3%
Using 2 workers (reduced due to system load)

Smart Caching

Hash-based caching skips unchanged files:

# First scan
📂 Files scanned: 145
⏱️  Total time: 47.28s

# Second scan (no changes)
📂 Files scanned: 0
⚡ Files cached: 145
⏱️  Total time: 2.15s  # 22× faster!

Parallel Processing

Multi-core scanning for massive speedups:

Single-threaded:  417.5 seconds
6 workers:         47.3 seconds  # 8.8× faster
24 workers:        ~18 seconds   # 23× faster

🏗️ Architecture

Scanner Pattern

All scanners follow a consistent pattern:

class PythonScanner(BaseScanner):
    """Scanner for Python files using Bandit"""

    def get_tool_name(self) -> str:
        return "bandit"

    def get_file_extensions(self) -> List[str]:
        return [".py"]

    def scan_file(self, file_path: Path) -> ScannerResult:
        # Run bandit on file
        # Parse JSON output
        # Map severity levels
        # Return structured issues
        return ScannerResult(...)

Auto-Registration

Scanners automatically register themselves:

# medusa/scanners/__init__.py
registry = ScannerRegistry()
registry.register(PythonScanner())
registry.register(JavaScriptScanner())
# ... all 41 scanners

Severity Mapping

Unified severity levels across all tools:

CRITICAL - Security vulnerabilities, fatal errors
HIGH - Errors, security warnings
MEDIUM - Warnings, code quality issues
LOW - Style issues, conventions
INFO - Suggestions, refactoring opportunities

🧪 Testing & Quality

Dogfooding Results

MEDUSA scans itself — and real-world projects:

Self-scan (473 files):
  ✅ Issues found: 114 (pre-filter) → 0 (post-filter)
  ✅ FP reduction: 100% on own codebase
  ⏱️  Time: 8.2s

OpenClaw benchmark (4,124 files, 751K LOC):
  🔍 Issues found: 825 (post-filter)
  ✅ FPs filtered: 11,436 (93.9% reduction)
  ⏱️  Time: 3.3 hours (42 scanners)

Performance Benchmarks

Project Size	Files	Time	Speed
Small (MEDUSA self-scan)	473	~8s	59 files/s
Medium	1,000	~45s	22 files/s
Large (OpenClaw)	4,124	~3.3h	0.34 files/s*

*Large project time dominated by external tool subprocesses (Semgrep, Trivy, GitLeaks). Built-in pattern scanning is near-instant.

🗺️ Roadmap

✅ Completed (v2026.3.0)

4,000+ Detection Patterns - Industry-leading AI security coverage
