Microsoft Execution Containers (MXC) provides policy-driven sandbox execution across Windows, Linux, and macOS. Box Mount exposes a Box folder inside that sandbox as a standard POSIX workspace with two-way sync, so your agent works with ordinary file operations while Box remains the system of record.
Before you begin
On the Box side, you need:
- Access to the Box Mount developer preview, including the Box Mount binary. To request access, complete the Box Mount developer preview form.
- A Box app configured for OAuth 2.0 or JWT. See Configure credentials.
- The ID of the Box folder you want to mount. This is the number at the end of the folder URL on Box.
Demo video
This demo mounts a Box folder, runs an agent inside MXC that reconciles invoices, purchase orders, and payments, and syncs a review memo and an exception workbook back to Box. Box credentials stay outside the MXC sandbox, and model traffic goes through the MXC proxy.
