Support Microsoft MXC sandboxing

Problem Statement

We currently lack a comprehensive sandboxing solution on windows. Given we are a highly regulated industry we would like a comprehensive sandboxing solution for Claude code in windows to limit access to base operating system locations where we might have sensitive data. Today our only option is docker with Linux containers hosted under WSL.

Proposed Solution

MIcrosoft is introducing the MXC framework (Microsoft Execution Containers). I would like Claude code to adopt this framework for both native windows sandboxing and within WSL. Competition like OpenAI has already pledged support.

Alternative Solutions

We are leveraging docker today and have started investigating wslc (windows container runtime).

Use Case Example

When working on a windows workstation which may contain or have access to sensitive data.
I would like to start my Claude core session in fully automatic mode to deliver software changes.
And feel comfortable it can’t gain access to the sensitive information, secrets or endpoints available to my workstation.
