Why createFolder is rated Medium
This tool creates a new folder, which is a reversible write operation. It does not execute arbitrary code, delete data, or move money. The severity is medium because creating folders could clutter a Drive or be used to organize exfiltrated data, but the action is easily undone by deleting the folder.
From the tool's definition Tool name 'createFolder' and description 'Create a new folder in Google Drive' indicate a write operation that creates a new resource.
Attacks that exploit this kind of access
The rule that runs createFolder 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 createFolder, this is the rule to start with:
createFolder 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 createFolder call is checked against it from then on.
