Introduction to the ElevenLabs MCP Server

The ElevenLabs MCP server is an open-source server implementation that connects AI models to ElevenLabs’ API through the Model Control Protocol (MCP). Developed by Anthropic, MCP facilitates secure communication between AI systems and external services. Here, the ElevenLabs MCP server acts as a bridge, allowing models like Claude or Cursor to leverage ElevenLabs’ advanced TTS, voice cloning, and audio processing features.

Why use the ElevenLabs MCP server? First, it simplifies audio generation. Developers can create natural-sounding speech from text prompts. Second, it supports voice cloning, enabling personalized audio outputs. Third, it offers transcription and advanced audio manipulation, making it ideal for diverse applications—think automated call centers, podcast tools, or interactive games. By integrating this server, you unlock a suite of audio tools without complex API management.

Next, we’ll walk through the setup process to get the server running on your system.

Setting Up the ElevenLabs MCP Server

Before you dive into using the ElevenLabs MCP server, you must set it up correctly. Fortunately, the process is straightforward, provided you meet the prerequisites and follow these steps.

Prerequisites

Ensure you have the following:

curl -LsSf https://astral.sh/uv/install.sh | sh

Installation Steps

Clone the Repository
Start by downloading the source code from GitHub. Open your terminal and run:

git clone https://github.com/elevenlabs/elevenlabs-mcp.git
cd elevenlabs-mcp

Install Dependencies
With uv, install the required packages effortlessly:

uv sync

Alternatively, use pip:

pip install -r requirements.txt

Set the API Key
The server needs your ElevenLabs API key. You can configure it in two ways:

export ELEVENLABS_API_KEY="your-api-key-here"

Launch the Server
Run the server with uv:

uv run elevenlabs_mcp --api-key=your-api-key-here

If you set the environment variable, skip the --api-key flag:

uv run elevenlabs_mcp

Once launched, the server listens on port 8000 by default. You’re now ready to configure it further or connect an AI model.

Configuring the ElevenLabs MCP Server

After installation, configure the ElevenLabs MCP server to suit your needs. The server offers flexibility through command-line options, environment variables, or a configuration file.

Key Configuration Options

Customize the server with these parameters:

To see all options, run:

uv run elevenlabs_mcp --help

Using a Configuration File

For complex setups, use a JSON file. Create config.json:

{
  "api_key": "your-api-key-here",
  "port": 8000,
  "host": "127.0.0.1",
  "log_level": "INFO"
}

Then start the server:

uv run elevenlabs_mcp --config=config.json

This method shines for managing multiple environments. With configuration complete, let’s explore integration.

Integrating the ElevenLabs MCP Server with AI Models

The ElevenLabs MCP server excels when paired with AI models. By connecting tools like Claude or Cursor, you enable natural language-driven audio tasks.

Integration with Claude Desktop

Follow these steps to connect Claude Desktop:

Enable Developer Mode

Configure MCP Settings

{
  "mcpServers": {
    "ElevenLabs": {
      "command": "uvx",
      "args": ["elevenlabs-mcp"],
      "env": {
        "ELEVENLABS_API_KEY": "your-api-key-here"
      }
    }
  }
}

Restart Claude
Close and reopen Claude Desktop. Now, issue prompts like “Generate speech: ‘Test message’ with ElevenLabs.”

Other MCP Clients

For custom clients, configure them to hit the server’s URL (e.g., http://127.0.0.1:8000). Ensure proper authentication if required. This flexibility makes the server adaptable to various workflows.

Using the ElevenLabs MCP Server for Text-to-Speech

A core feature of the ElevenLabs MCP server is its text-to-speech capability. Here’s how to use it effectively.

Generating Basic Speech

With an AI model connected, send a prompt:

The MCP server handles the API call behind the scenes, delivering the output seamlessly.
