Why renameDocumentTab is rated Medium
This tool modifies document properties (tab naming) reversibly. It creates or updates metadata within a Google Doc but does not execute arbitrary code, delete data, move money, or cause destructive changes. The blast radius is moderate—renaming tabs could confuse collaborators or break references, but changes are easily undone.
From the tool's definition Tool name 'renameDocumentTab' and description 'Rename an existing Google Doc tab' indicate modification of document structure metadata without deletion or data loss.
Attacks that exploit this kind of access
The rule that runs renameDocumentTab safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Google Drive, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For renameDocumentTab, this is the rule to start with:
renameDocumentTab 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 Google Drive, apply this rule, and every renameDocumentTab call is checked against it from then on.
