Summary

ElevenLabs' official MCP server — generate speech, clone voices, transcribe audio, and build voice agents.

Features

  • Clone voices and design new ones from a description
  • Transcribe audio and isolate voices from noise

Installation

Set up this MCP server in your favorite AI agent — copy a ready-made configuration below.

Any MCP-compatible agent

Most agents (Claude, Cursor, Windsurf, VS Code, and more) read a standard mcpServers configuration.

  1. Open your agent's MCP configuration file.
  2. Merge the snippet below into it, filling in the environment variables with your own values.
  3. Restart the agent — the "ElevenLabs" tools will be available.

Description

ElevenLabs' official MCP server puts its entire audio platform behind tools an assistant can call, so producing narration becomes part of a conversation rather than a separate application.

What it covers
  • Text to speech across a large voice library and many languages, with control over stability and style
  • Voice cloning from an audio sample, and voice design from a text description of how a voice should sound
  • Speech to text transcription with speaker diarisation
  • Audio isolation for stripping background noise from a recording
  • Sound effects generated from a description
  • Conversational agents — create and configure voice agents, and initiate outbound calls
  • Voice library search for finding a voice matching a description
Practical uses

Narrating a script the assistant just wrote, producing a localised version of a video's audio, transcribing a recording and then acting on the transcript, and prototyping voice agents without writing integration code.

Requires an ElevenLabs API key; runs with uvx elevenlabs-mcp. Generated audio is written to a configurable output directory.
