io.elevenlabs/mcp (Model Context Protocol Server)

This MCP server manages ElevenLabs voice agents and supports generation of speech, music, sound effects, images, and video. It is described as a “plugin-native” integration for coding agents, intended to work with Cursor, Claude Code, and OpenAI Codex.

🛠️ Key Features

Manage ElevenLabs voice agents
Generate speech
Generate music
Generate sound effects
Generate images
Generate video
Integrate with Cursor, Claude Code, and OpenAI Codex

🚀 Use Cases

Driving ElevenLabs capabilities from a coding agent
Using agent “skills” to control the bundled ElevenLabs MCP server

⚡ Developer Benefits

Skill organization in multiple trees for agent use
“skills/mcp/” skills teach agents how to drive the bundled MCP server
“skills/general/” contains general ElevenLabs product skills copied from the official upstream repository

⚠️ Limitations

General skills under skills/general/ are not meant to be edited here; changes should go upstream

ElevenLabs Plugin

Voice AI capabilities for your coding agent — powered by ElevenLabs. Works with Cursor, Claude Code, and OpenAI Codex.

What's included

Skills

Skills live in three trees:

skills/general/ — general ElevenLabs product skills, copied from the official elevenlabs/skills repository. Don't edit these here; contribute upstream instead.
skills/mcp/ — plugin-native skills that teach agents how to drive the bundled ElevenLabs MCP server.
architect/skills/ — Architect skills: opinionated workflows for building and iterating on ElevenLabs agents, mirrored from the internal Architect plugin. Shared payload examples live in architect/reference/.

architect-create-llm-test	Create a single-turn test that checks what the agent says
architect-create-simulation-test	Create a multi-turn test where a simulated user talks to the agent
architect-create-tool-test	Create a test asserting the agent calls, or avoids, a specific tool
architect-create-webhook-tool	Give an agent a new webhook tool that calls an external API
architect-edit-existing-tool	Change an existing tool on an agent safely
architect-edit-string-fields	Edit long text fields like system prompts without clobbering the rest
architect-edit-workflows	Build or change an agent's workflow graph
architect-explain-test-runs	Explain why a test or test run passed or failed
architect-explore-agent	Map an agent's current setup before changing it
architect-generate-agent	Generate a new agent from a description
architect-get-agent-ci-green	Drive a red agent test suite to green
architect-llm-selection	Choose the right LLM for an agent
architect-manage-procedures	Add, edit, rename, and inspect an agent's procedures
architect-migrate-from-competitor	Migrate a voice agent from Retell, Vapi, or Bland
architect-migrate-to-procedures	Move a system-prompt-driven agent to a procedure-driven setup
architect-mock-all-tools	Mock every tool call so simulation tests are deterministic
architect-post-call-data	Configure post-call data collection and evaluation criteria
architect-review-live-calls	Review recent production conversations and route the findings
architect-schedule-launch	Stage a change on a branch and hold the merge until go-live
architect-secure-for-production	Make an agent safe, secure, and production-ready
architect-structured-procedures	Author structured, deterministic procedures
architect-troubleshoot-tool-errors	Diagnose a misbehaving tool from its exact error
architect-turn-taking-latency	Tune turn taking and agent response latency
architect-update-config-safely	Change agent settings with safe partial patches
code-tools	Generate JavaScript/TypeScript modules for ElevenLabs code tools
fix-agent-qa-ticket	Fix a QA triage ticket end to end with a verified, branch-scoped fix

Architect also ships one command: /thermo-nuclear-agent-triage-burndown, which burns down an agent's whole conversation-triage queue — cluster tickets by root cause, fix each cluster, then comment on and resolve every ticket.

MCP Server

The ElevenLabs hosted MCP server — no local install, no API key. Your agent authenticates with your ElevenLabs account over OAuth and gets access to agent management (create, update, list, duplicate, delete agents; inspect widget config, links, and knowledge base size; estimate LLM usage) and text-to-speech generation. Configured in mcp.json.

Installation

Cursor

Install from the Cursor marketplace, or add this repo as a plugin. When Cursor connects to the MCP server, sign in with your ElevenLabs account to complete the OAuth flow.

Claude Code

code

/plugin marketplace add elevenlabs/plugin
/plugin install elevenlabs@elevenlabs

Or install directly for development: claude --plugin-dir /path/to/plugin

Codex

code

codex plugin marketplace add elevenlabs/plugin

Then install via /plugins in Codex, or invoke skills with $skill-name.

Skills only (any agent)

bash

npx skills add elevenlabs/skills

Requirements

An ElevenLabs account — you'll sign in via OAuth when your agent connects to the MCP server
Internet access
