sandbox-mcp: fresh Windows Sandbox machines for testing apps, via MCP
An MCP server and CLI that spins up throwaway Windows Sandbox machines so coding agents can install and test apps in a clean Windows environment.
Why it matters
Gives coding agents a real, disposable Windows machine to run software in — closing the gap between Linux sandboxes and Windows-only apps.
What you could build with it
A QA team could wire sandbox-mcp into their coding agent's workflow so every agent-built Windows installer gets installed and smoke-tested in a fresh sandbox before a human ever touches it.
Does it hold up?
Early but usable: released 6 Nov and already at v1.2.0, with third-party writeups clocking fresh sandboxes at roughly 35-50 seconds; Windows Pro, Enterprise or Education only.
