A Model Context Protocol (MCP) server that provides text-to-speech capabilities using the Rime API. This server downloads audio and plays it using the system's native audio player.

## Features

- Exposes a `speak` tool that converts text to speech and plays it through system audio
- Uses Rime's high-quality voice synthesis API

## Requirements

- Node.js 16.x or higher
- A working audio output device
- macOS: Uses `afplay`

There's sample code from Claude for the following that is not tested 🤙✨
  - Windows: Built-in Media.SoundPlayer (PowerShell)
  - Linux: mpg123, mplayer, aplay, or ffplay
