Security tests for MARM Docker Container
Tests security features of the actual production Docker container.

Usage:
1. Make sure MARM Docker container is running:
   docker run -d --name marm-mcp-server -p 8001:8001 lyellr88/marm-mcp-server:latest
2. Run the script:
   python tests/test_docker_security.py
