Why create_drive_folder is rated Medium
This tool creates or modifies file system structure (folders) in a Drive service. Creation is reversible—folders can be deleted. While it creates new resources, it does not execute arbitrary code, delete irreversibly, move money, or read data. The idempotent behavior confirms it is safe to retry and cannot cause unexpected side effects.
From the tool's definition Tool description states 'Idempotently create a Drive folder path' and 'creating missing parents like mkdir -p', indicating folder creation which modifies data reversibly.
Attacks that exploit this kind of access
The rule that runs create_drive_folder 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 create_drive_folder, this is the rule to start with:
create_drive_folder 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 Huly, apply this rule, and every create_drive_folder call is checked against it from then on.
