This setup includes various security measures like read-only rootfs, dropped capabilities, non-root user, and memory/PID limits. The gVisor runtime intercepts system calls, preventing direct host kernel access and mitigating potential exploits. This configuration has been audited on 8,764 MCP servers, with future plans for an egress proxy with an allowlist for outbound communication. AI
