THE RISK

Why generate_speech needs a policy

This tool triggers an external operation (ElevenLabs TTS API call) to generate audio content. It executes an external service call whose effects (audio generation, potential API usage/costs) depend on the input arguments. It is not a simple read, and while it may incur minor costs, it is not a direct financial transaction.

POLICY

How to control generate_speech

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 generate_speech:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "generate_speech": {
      "limits": [
        {
          "counter": "generate_speech_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

generate_speech stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. 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.
