Key point
The feature is in private preview, requiring users to request access from Box and unmount before stopping the sandbox to ensure data persistence.
Details
- Box Mount allows agents running in Vercel Sandbox to read and write Box files using standard filesystem operations by syncing a Box folder with a sandbox directory.
- Data written by the agent is saved to Box after the sandbox is deleted, provided the user unmounts before stopping the sandbox.
- The feature is currently in private preview, requiring users to request access from Box and follow specific documentation for setup.
- A contract-review example demonstrates the use of AI Gateway to review a synthetic contract in Vercel Sandbox and save the results back to Box.
- Security is maintained by running the sync process and the agent as separate sandbox users, keeping Box credentials isolated from the agent's workspace.
