🔒 Security

🛡️ Security Features

• No Privilege Escalation: Runs with minimal required permissions
• Input Validation: All inputs are validated and sanitized
• Error Sanitization: Sensitive information is not exposed in errors
• Audit Logging: All operations are logged for security auditing

🔐 Security Best Practices

• Docker Socket Access: Requires explicit Docker socket mounting
• No Secrets Storage: No credentials or secrets are stored
• Read-Only Operations: Default operations are read-only for safety
• Container Isolation: Runs in isolated container environment

🚨 Security Considerations

# Run with non-root user (recommended)
docker run --user 1000:1000 -v /var/run/docker.sock:/var/run/docker.sock mcp-docker-deployer

# Limit Docker socket access
docker run --cap-drop ALL --cap-add DAC_OVERRIDE -v /var/run/docker.sock:/var/run/docker.sock mcp-docker-deployer

# Use read-only filesystem
docker run --read-only -v /var/run/docker.sock:/var/run/docker.sock -v /tmp:/tmp mcp-docker-deployer
