Twelvelabs Mcp Server
Despite the confusing name, this connects Claude to the ElevenLabs Conversational AI API, not TwelveLabs video platform. You get agent management (list, configure, update prompts and LLM settings), knowledge base operations (add docs from text or URL, read full extracted content, delete), conversation history with full transcripts and data collection analysis, and voice browsing. It exposes capabilities the official ElevenLabs MCP doesn't cover, like reading agent webhooks, updating temperature settings, and pulling complete system prompts. Reach for this when you need Claude to inspect or modify your ElevenLabs voice agents programmatically rather than through their dashboard.

TwelveLabs MCP Server
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 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
