What drive_file_rename does on TrekMail MCP Server
AI agents use drive_file_rename to create or update resources in TrekMail MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your TrekMail MCP Server environment.
Why drive_file_rename is rated Medium
File renaming is a write operation that modifies file metadata reversibly. It does not delete data (not Destructive), does not execute code (not Execute), and does not involve financial transactions (not Financial). The medium severity reflects that renaming files could cause confusion or disrupt workflows if misused, but the operation is reversible.
From the tool's definition Tool description states 'Rename a file', which is a reversible modification operation. The presence of validation for name parameters indicates this modifies file metadata.

The rule that runs drive_file_rename safely
PolicyLayer is an MCP gateway: it sits between your AI agents and TrekMail MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For drive_file_rename, this is the rule to start with:
drive_file_rename 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.
The button opens the PolicyLayer dashboard: create your workspace, connect TrekMail MCP Server, apply this rule, and every drive_file_rename call is checked against it from then on.
