"env": {
"ELEVENLABS_API_KEY": "your-elevenlabs-api-key-here"

}From the project's GitHub README.
This project is not affiliated with TwelveLabs (the video understanding platform). It is an MCP server for the ElevenLabs Conversational AI API — voice agents, knowledge bases, conversations, and TTS. The name "TwelveLabs" is the project codename only.
An enhanced MCP (Model Context Protocol) server that gives Claude direct access to the ElevenLabs Conversational AI API -- including capabilities the official ElevenLabs MCP connector doesn't expose.
ELEVENLABS_API_KEY=your-key npx twelvelabs-mcp-server
git clone https://github.com/micro-JAY/twelvelabs-mcp-server.git
cd twelvelabs-mcp-server
npm install --include=dev
npm run build
Edit ~/Library/Application Support/Claude/claude_desktop_config.json:

"env": {
"ELEVENLABS_API_KEY": "your-api-key-here"
}

All tools share a single Axios client instance (src/client.ts) initialised from
ELEVENLABS_API_KEY at startup. Tool implementations live in src/tools/ -- one
file per domain -- and are registered onto the McpServer in src/index.ts. The
server communicates over stdio transport (stdin/stdout), which is why all debug
logging uses console.error (stderr), not console.log.
