Why speech_to_speech needs a policy

The tool name suggests audio transformation (speech-to-speech conversion), which could involve reading audio input and writing/generating audio output. However, the description is completely empty, making it impossible to determine the exact behavior. Given the Ableton Live context (music production), it may relate to voice/audio processing. Without more information, confidence is low.

From the tool's definition Tool name is 'speech_to_speech'; description is empty or uninformative.

POLICY

How to control speech_to_speech

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "speech_to_speech": {
      "limits": [
        {
          "counter": "speech_to_speech_rate",
          "window": "minute",
          "max": 60,
          "scope": "grant"
        }
      ]
    }
  }
}

speech_to_speech gets a rate cap, and everything else on the server is denied unless you say otherwise.

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