Overview

What is MCP TTS Server?

MCP TTS Server is a Text-to-Speech server built on the Model Context Protocol (MCP) framework. It provides a unified interface to multiple TTS engines—Kokoro TTS (local) and OpenAI TTS (cloud)—for use with Claude Desktop and other MCP-compatible hosts.

How to use MCP TTS Server?

Install prerequisites (Python ≥3.10, uv), clone the repository, create a virtual environment, and install dependencies. Configure an OpenAI API key in a .env file if using the OpenAI engine. Integrate with Claude Desktop via fastmcp install or by adding the server to claude_desktop_config.json. The server exposes the tts tool to convert text to speech with engine, voice, speed, and instructions parameters.

Key features of MCP TTS Server

  • Supports Kokoro (local) and OpenAI (cloud) TTS engines
  • Real-time streaming audio playback
  • MCP protocol integration with Claude and other LLMs
  • Configurable voice selection for both engines
  • Voice customization via natural language instructions (OpenAI)
  • Playback control: stop and clear the audio queue

Use cases of MCP TTS Server

  • Enabling Claude to speak responses using a local or cloud TTS engine
  • Generating speech offline with Kokoro without external API calls
  • Using OpenAI’s high-quality voices with customizable instructions for character or emotion
  • Stopping ongoing speech and clearing queued requests on demand
