THE RISK

Critical Risk

Why drive__delete needs a policy

This tool permanently removes data from Proton Drive and cannot be undone. Deletion of files/folders is an irreversible operation, making it Destructive rather than merely Write. An AI agent misusing this tool could accidentally or maliciously delete user files or entire folder structures, causing significant data loss.

From the tool's definition Tool name is 'drive__delete' with description 'Delete a file or folder from Proton Drive'. The verb 'delete' combined with the action of removing files or folders indicates irreversible data destruction.

POLICY

How to control drive__delete

PolicyLayer is an MCP gateway — it sits between your AI agents and Proton-MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for drive__delete:

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "drive__delete"
  ]
}

drive__delete disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Create a free account and register Proton-MCP — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
