🔧 Troubleshooting (based on real experience)

Common Issues

1. Security Tools Installation Failure

# Issue: pip3 permission error
# Solution:
pip3 install --user semgrep bandit

# Or with system permissions
sudo pip3 install semgrep bandit

2. TypeScript Compilation Errors

# Issue: Strict type checking errors
# Temporary solution: Skip compilation and run with JavaScript
node test-all-security.js  # Test without TypeScript build

# Permanent solution: Fix tsconfig.json configuration

3. Docker Permission Issues

# Issue: No Docker execution permissions
# Solution:
sudo usermod -aG docker $USER
newgrp docker

4. Port Conflicts

# Issue: Ports 3000, 3001 already in use
# Solution:
export MCP_PORT=3002
node test-vulnerable-server.js  # Use different port

5. Vulnerable Dependencies Installation Failure

# Issue: node-sass compilation error
# Solution: Install excluding problematic packages
cd test-vulnerable-dependencies
npm install --ignore-engines
