What is the Chatterbox MCP MCP server?

If you already use Chatterbox MCP, the chatterbox mcp mcp server is the piece that lets your assistant work with it directly. A simplified Model Context Protocol (MCP) server that provides text-to-speech generation with automatic playback using the Chatterbox TTS model. The server loads the model automatically on first use and provides real-time progress.

What the server does

This MCP server exposes Chatterbox TTS functionality through a single, streamlined tool that generates speech from text and plays it automatically. The server handles model loading, progress reporting, temporary file management, and audio playback seamlessly.

Credentials and setup notes

Configuration is passed through the environment: CHATTERBOX_AUDIO_DIR, CHATTERBOX_AUDIO_TTL_HOURS. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.

Installation

Installation goes through your MCP client rather than a global install: point it at mcp on PyPI and it is fetched when the client starts. The copy-paste blocks for Claude Desktop, Claude Code and Cursor are further down this page.

Where it fits

Among the AI and media services options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. It is maintained by digitarald; worth a glance at recent repository activity before you build anything load-bearing on it.

SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.

Worth knowing first

  • It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
  • Keep per-call confirmation enabled while you learn its behaviour; it is the cheapest safeguard you have.
