elevenlabs-voice-mcp

A tiny Model Context Protocol server that gives Claude a voice through the ElevenLabs text-to-speech API.

It exposes two tools over stdio so any MCP client (Claude Code, Claude Desktop) can speak its responses out loud or discover voices — operated in plain English:

Tool	What it does
list_voices	List the voices available on your ElevenLabs account (id + name + labels).
text_to_speech	Turn text into an MP3 with a chosen voice/model, save it, and play it.

Multilingual by default (eleven_multilingual_v2), so Polish reads correctly too.

Why

I build agentic systems with Claude and MCP. This wires ElevenLabs into that world as a first-class tool: instead of a one-off API script, Claude itself can decide to speak, pick a voice, and read something back — the same MCP pattern I use elsewhere, pointed at ElevenLabs' audio models.

Setup

npm install
npm run build              # or: npm run dev   (runs from source via tsx)
export ELEVENLABS_API_KEY=sk_...   # free key: elevenlabs.io → Profile → API Keys
npm start

Use it from Claude Code

claude mcp add elevenlabs-voice -- node /absolute/path/to/dist/index.js
# (set ELEVENLABS_API_KEY in your environment first)

Or add it to your Claude Desktop config:

{
  "mcpServers": {
    "elevenlabs-voice": {
      "command": "node",
      "args": ["/absolute/path/to/elevenlabs-voice-mcp/dist/index.js"],
      "env": { "ELEVENLABS_API_KEY": "sk_..." }
    }
  }
}

Then just ask Claude: "list the ElevenLabs voices" or "say 'cześć, świecie' out loud."

Notes

• A free ElevenLabs account includes enough monthly characters to try this out.
• Playback uses the OS default (afplay on macOS, aplay on Linux, PowerShell on Windows); generation still works headless if no player is present.
• Override the default voice/model with ELEVENLABS_VOICE_ID / ELEVENLABS_MODEL_ID, or per call via the tool arguments.
