Remove a user
AI agents call drive_permission_delete to permanently remove resources in Google Drive MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Removing a permission (revoking access) is a destructive, irreversible action. Once a user's permission is deleted, they lose access immediately, and there is no undo mechanism in Google Drive's permission model without explicitly re-adding them. The blast radius is high because an AI agent could inadvertently revoke access for many users across files, disrupting collaboration.
From the tool's definition 'Remove a user' — deleting a permission is an irreversible removal of a user's access to a resource
Attacks that exploit this kind of access
Remove a user. It is categorised as a Destructive tool in the Google Drive MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Google Drive MCP Server MCP server in PolicyLayer and add a rule for drive_permission_delete: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Google Drive MCP Server. Nothing to install.
drive_permission_delete is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the drive_permission_delete rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for drive_permission_delete. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
drive_permission_delete is provided by the Google Drive MCP Server MCP server (rishipradeep-think41/google-drive-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
