MCP-Specific Tools

Custom Security Scanner

A comprehensive Python-based scanner for MCP implementations:

#!/usr/bin/env python3
"""
MCP Security Scanner
Scans MCP servers for common vulnerabilities
"""

class MCPScanner:
    def __init__(self, target_url):
        self.target_url = target_url
        self.session = requests.Session()
    
    def scan_sql_injection(self):
        """Test for SQL injection vulnerabilities"""
        payloads = [
            "'; DROP TABLE users; --",
            "' OR '1'='1",
            "' UNION SELECT NULL--"
        ]
        # Implementation details...
    
    def scan_command_injection(self):
        """Test for command injection vulnerabilities"""
        # Implementation details...
    
    def scan_authentication_bypass(self):
        """Test for authentication bypass"""
        # Implementation details...

Container Security

Docker Security Scanning

# Scan container images
docker run --rm -v /var/run/docker.sock:/var/run/docker.sock \
  aquasec/trivy image your-mcp-server:latest

# Use docker-bench-security
git clone https://github.com/docker/docker-bench-security.git
cd docker-bench-security
sudo sh docker-bench-security.sh

Network Security Tools

TLS/SSL Testing

# Test SSL configuration
sslyze --regular your-mcp-server.com:443

# Use testssl.sh
testssl.sh https://your-mcp-server.com

Network Scanning

# Port scanning with nmap
nmap -sV -sC your-mcp-server.com

# Service discovery
nmap -sU -sS your-mcp-server.com

CI/CD Integration

Automated Security Testing

# .github/workflows/security.yml
name: Security Scan
on: [push, pull_request]

jobs:
  security-scan:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v2
      
      - name: Run Bandit Security Scan
        run: |
          pip install bandit
          bandit -r . -f json -o bandit-report.json

Monitoring and Logging

Security Event Monitoring

# Example: Send security events to SIEM
def send_security_event(event_type, details):
    event = {
        "timestamp": "2024-01-01T00:00:00Z",
        "source": "mcp-server",
        "event_type": event_type,
        "details": details,
        "severity": get_severity(event_type)
    }
    
    # Send to SIEM/SOAR platform
    requests.post(
        "https://your-siem.com/api/events",
        headers={"Authorization": "Bearer TOKEN"},
        json=event
    )
