WHAT IT DOES

What drive_restore does on Mcp

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

Parameter	Type	Required	Description
`drive`	string	Yes	Drive name or drv_… id
`versionId`	string	Yes	dv_… id from drive_history

Parameters from the server's own tool schema.

RISK

Why drive_restore is rated Medium

This tool creates or modifies data reversibly by restoring a prior version and committing it as a new version. While it changes state, the operation is reversible (prior versions remain accessible) and does not permanently delete data. This qualifies as Write rather than Destructive.

From the tool's definition The tool description states 'Restore a drive to a prior version (commits a new version; nothing is lost).' This operation modifies the state of a drive by reverting it to a prior version, which is a reversible write operation.

RECOMMENDED RULE

The rule that runs drive_restore safely

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

drive_restore Rate-limited

drive_restore 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.
