THE RISK

High Risk

This tool executes an external API call to convert text into audio, producing a generated artifact. It is not a simple data read/write but an execution of a generative process. Misuse could involve generating deceptive audio using cloned voices, raising moderate risk concerns around impersonation or synthetic media abuse.

From the tool's definition 'Convert text to speech. Supports cloned voices + emotion tags' — triggers external API operation to synthesize audio from text input

HOW TO CONTROL VENICE_TTS

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

policy.json

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

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