Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "twelvelabs": {
      "command": "npx",
      "args": [

Common questions

Is Twelvelabs MCP Server safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: ELEVENLABS_API_KEY

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.1) reached the registry 7 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

TwelveLabs MCP Server

This project is not affiliated with TwelveLabs (the video understanding platform). It is an MCP server for the [ElevenLabs](https://elevenlabs.io) 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 any compatible MCP client direct access to the ElevenLabs Conversational AI API -- including capabilities the official ElevenLabs MCP connector doesn't expose.

What this covers

Agents -- list, get full config (including LLM model + temperature), update prompt/settings, manage webhooks and file uploads
Knowledge Base -- list, read full content, add text/URL docs, delete docs
Conversations -- filter and tag history, inspect transcripts, and rerun post-call analysis/evaluations
Voices -- list and search available voices

Prerequisites

Node.js >= 18
ElevenLabs API key -- get one at elevenlabs.io

Quick Start

Option A: npx (no clone needed)

ELEVENLABS_API_KEY=your-key npx twelvelabs-mcp-server

Option B: Clone and build

git clone https://github.com/micro-JAY/twelvelabs-mcp-server.git

cd twelvelabs-mcp-server npm install --include=dev npm run build

Connect an MCP client

Add an equivalent server entry to your MCP client's configuration. The config file location and surrounding syntax vary by client; this is the standard stdio server definition:

"mcpServers": { "twelvelabs": { "command": "node", "args": ["/path/to/twelvelabs-mcp-server/dist/index.js"], "env": { "ELEVENLABS_API_KEY": "your-api-key-here" } } } }

Restart or reconnect your MCP client. You should see twelvelabs in its available tools list.

Use it

Ask your MCP-enabled assistant to use the tools, for example:

"List my agents"

"Get the full config for agent_1001kjbh14xce5kbreh55ydf4rae"

"Show me the last 10 conversations for that agent"

"Get the transcript and analysis for conversation_xyz"

Compatibility

This server works with MCP clients that support the stdio transport and let you configure environment variables for a local server process. Clients that only support remote HTTP MCP servers need a compatible stdio bridge or proxy.

Security

Input validation -- all tool parameters are validated with Zod schemas before reaching the API
HTTPS enforcement -- webhook URLs are validated to use HTTPS only
Path traversal protection -- document and agent IDs are sanitized to prevent path traversal
Error sanitization -- internal errors are caught and returned as safe MCP error responses; raw stack traces are never exposed to the client

Development

npm run dev   # watch mode with tsx -- auto-reloads on file changes

npm run build # compile to dist/

Architecture Note

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.
