sandbox-mcp gives AI agents a throwaway Windows PC for app testing
Sorted AI18h agosandbox-mcp is an open-source command-line tool (sbx) with an optional MCP server that drives Windows Sandbox, the disposable Windows desktop that comes with Windows Pro and Enterprise. An agent can boot a fresh machine, deploy an app, click through it with UI Automation, and keep screenshots, recordings and crash reports after the machine is deleted. It never installs missing runtimes unless you opt in, so it shows what breaks on a clean customer PC; the project says its measured sample runs take roughly 40 to 50 seconds end to end. Limits: one sandbox at a time, nothing persists, and it only tests Windows apps. It is an early project, not independently tested.
Why it matters: If you ship Windows software to clients, have your coding agent run each build on a clean sandbox before release to catch missing dependencies such as a Visual C++ runtime. You need Windows Pro or Enterprise to use it.
