Microsoft Open-Sources MXC: Cross-Platform Sandbox for Untrusted AI Code
sull · x · 2026-08-06
Microsoft has released an early preview of its eXecution Container (MXC) on GitHub. It is a sandboxed code execution system designed to safely run untrusted code—such as LLM outputs, plugins, and tools—across Windows, Linux, and macOS. MXC abstracts multiple containment backends, ranging from OS-native process sandboxes to full virtual machines, behind a unified JSON configuration schema and TypeScript SDK.
