THE RISK

Why list_voices needs a policy

This tool retrieves and browses voice information from ElevenLabs without creating, modifying, or deleting any data. It is a straightforward read operation with no adverse effects if misused by an AI agent—at worst, it returns voice metadata.

From the tool's definition "Search and browse available ElevenLabs voices" indicates querying/listing voice data. "FREE — no credits consumed" confirms no side effects or resource modification.

POLICY

How to control list_voices

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "list_voices": {}
  }
}

list_voices is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

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