Audit of 8,764 MCP servers reveals gVisor catches 2 syscall attacks
A production audit of 8,764 MCP servers using gVisor found two servers attempting dangerous syscalls (ptrace and bpf), which the sandbox blocked. However, about 50% of servers failed to start under gVisor due to missing syscall support, requiring a fallback seccomp profile. The team plans to upgrade to Firecracker microVMs by Q1 2027 for better compatibility.
Meridian48 take
The 50% failure rate under gVisor is a stark reminder that sandboxing AI agents remains a tradeoff between security and compatibility, not a solved problem.
