WHAT IT DOES

What kokoro_uninstall does on Voice Mode

AI agents call kokoro_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

Critical Risk

Why kokoro_uninstall needs a policy

This tool performs irreversible deletion and removal operations. It uninstalls software, removes configurations, deletes downloaded models, and can purge all associated data. While the model removal and data deletion are optional parameters, the core action of uninstalling the service and removing configurations is inherently destructive and cannot be undone without reinstalling.

From the tool's definition Uninstall kokoro-fastapi and optionally remove models and data. Tool will stop services, remove service configurations, remove the installation, and optionally remove downloaded models and all Kokoro-related data including logs and cache.

POLICY

How to control kokoro_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 kokoro_uninstall:

policy.json

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

kokoro_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.
