WHAT IT DOES

What restore_drive_file_version does on Huly

AI agents use restore_drive_file_version to create or update resources in Huly, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Huly environment.

RISK

Why restore_drive_file_version is rated Medium

While 'restore' might sound like recovery, the tool's behavior is to change the current state of a file reversibly by setting it to a prior version. This is a modification operation, not deletion (hence Write, not Destructive).

From the tool's definition Tool explicitly uses 'restore' on a Drive file version, which modifies the current state of the file by reverting to a previous version.

RECOMMENDED RULE

The rule that runs restore_drive_file_version safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Huly, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For restore_drive_file_version, this is the rule to start with:

restore_drive_file_version Rate-limited

restore_drive_file_version stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
