Docker Sandboxing for MCP Servers: gVisor + Network None
A developer shares a hardened Docker sandbox configuration for MCP servers, combining --network none, read-only rootfs, capability dropping, and gVisor runtime. The setup has been audited against 8,764 MCP servers, catching syscalls like ptrace, bpf, mount, and kexec_load. The approach addresses common sandbox escape vectors while maintaining a minimal resource footprint.
