Microsoft Releases MXC 0.8.0 to Sandbox AI Agents Across 3 Operating Systems

Summary
MXC 0.8.0 adds updated policy controls and stronger networking support to isolate AI agents from host systems and curb access to private data or unexpected APIs.
The open-source Rust project uses virtualization, secure containers and microVMs to enforce a default-deny model, letting developers define one JSON policy for Windows, macOS and Linux.
GitHub Copilot is already using MXC experimentally in CLI sessions, where sandboxed mode limits file-system access to selected directories and allows outbound-only connectivity.
MXC also supports audit and learning modes so teams can observe blocked behavior, tune policies, and then deploy tighter sandboxes without working directly with kernel-level hypervisor tools.
Microsoft is positioning MXC for edge agents, Windows Sandbox, Hyperlight microVMs and Windows 365 for Agents, though the project remains an early preview likely to change before final release.
