WHAT IT DOES

What list_drive_items does on VaultAssist

AI agents call list_drive_items to retrieve information from VaultAssist without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why list_drive_items is rated Low

This tool queries and retrieves directory contents from Google Drive without creating, modifying, deleting, or executing anything. While it operates on user data within a multi-user system, the information exposure is limited to the authenticated user's own Drive contents or shared folders they have read access to.

From the tool's definition Tool description explicitly states 'List files and folders' which is a retrieval operation with no data modification. The verb 'list' is a canonical Read operation.

list_drive_items Allowed

list_drive_items is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
