Runtime Isolation

This section establishes secure execution environments for MCP servers using containerization, virtualization, and system-level isolation techniques to limit the impact of compromised or malicious code.

Key Practices

• Default to Docker containers or lightweight VMs for MCP execution
• Use dedicated VPS environments for high-risk workloads
• Implement capability dropping and seccomp profiles
• Apply principle of least privilege to file system access
• Isolate network communications and restrict outbound connections

Implementation Guide

This section will cover:

• Docker security best practices for MCP containers
• VPS and VM isolation configurations
• Linux security modules (AppArmor, SELinux) setup
• Network isolation and firewall rules
• Resource limits and monitoring

Risk Mitigation

Addresses threats including system compromise, lateral movement, privilege escalation, and resource exhaustion attacks that could impact the host system or other workloads.
