The AI Agent Sandbox You Already Have: A Drive Letter

说明与用途

使用Windows驱动器字母作为AI代理的隔离沙箱，提供简单且无成本的文件访问保护。

问题

Prevent an AI agent from accessing or modifying files outside a designated workspace while keeping setup simple.

结果

Using a drive letter as a sandbox provides OS-level isolation without containers, learning curve, or subscription costs, suitable for simple protection needs.

工作流

• Map a local or cloud folder to a drive letter using Windows subst or WebDAV.
• Configure the AI agent to use the mapped drive letter as its working directory.
• Run the agent; it can read/write only within that drive.
• Verify that the agent cannot access files outside the mapped drive.
• Optional: add firewall or container layers for stronger isolation.

证据

Everyone is building fancy sandboxes for AI agents. But you already have one: a Windows drive letter.

Map a folder to a letter. Point your agent at that letter. Done.

The agent can write all day on that drive. It cannot see or touch anything outside it.
