Generate audio from a structured script with multiple voices and actors
AI agents invoke generate_audio_script to trigger actions in ElevenLabs MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.
This tool triggers an external API operation (ElevenLabs TTS) to synthesize audio from a structured script. It executes a computation/service call that produces a new artifact, going beyond a simple data write. The blast radius is medium — it can consume API credits and generate audio content at scale with multiple voices, but does not delete data or move money directly.

Documented attack patterns abuse exactly the kind of access generate_audio_script gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and ElevenLabs MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for generate_audio_script:
{
"version": "1",
"default": "deny",
"tools": {
"generate_audio_script": {
"limits": [
{
"counter": "generate_audio_script_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
}generate_audio_script 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.

Generate audio from a structured script with multiple voices and actors. It is categorised as a Execute tool in the ElevenLabs MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the ElevenLabs MCP Server MCP server in PolicyLayer and add a rule for generate_audio_script: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches ElevenLabs MCP Server. Nothing to install.
generate_audio_script is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the generate_audio_script rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for generate_audio_script. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
generate_audio_script is provided by the ElevenLabs MCP Server MCP server (mamertofabian/elevenlabs-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from ElevenLabs MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
