WHAT IT DOES

What whisper_uninstall does on Voice Mode

AI agents call whisper_uninstall to permanently remove resources in Voice Mode — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

THE RISK

Why whisper_uninstall needs a policy

This tool performs irreversible deletion of software installations, service configurations, downloaded models, and user data (logs, transcriptions). These actions cannot be undone without reinstalling and reconfiguring from scratch.

From the tool's definition Tool description explicitly states it will "Uninstall whisper.cpp", "Remove service configurations", "Remove the whisper.cpp installation", and "Optionally remove downloaded models" and "remove all Whisper data including logs and transcriptions".

POLICY

How to control whisper_uninstall

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

policy.json

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

whisper_uninstall 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 Voice Mode — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
