### Description (declared)

# Chatterbox TTS MCP Server

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 notifications to keep users informed throughout the process.

## Overview

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.

## Features

### Single Tool: `speak_text`

The `speak_text` tool provides complete text-to-speech functionality:

- **Parameters:**
  - `text` (required): The text to convert to speech
  - `exaggeration` (optional): Controls expressiveness (0.0-1.0, default 0.5)
  - `cfg_weight` (optional): Controls classifier-free guidance (0.0-1.0, default 0.5)

- **Features:**
  - Automatic model loading with progress notifications
  - Generates speech using temporary files (auto-cleanup)
  - Plays audio automatically on macOS using `afplay`
  - Real-time progress updates during all phases:
    - Model initialization and loading
    - Speech generation
    - Audio playback

### Resource: `chatterbox://model-info`

Get information about the TTS model status and device capabilities:
- Model loading status (loaded/not loaded)
- Device information (MPS/CUDA/CPU)
- Hardware acceleration availability

## Progress Notifications

The server provides detailed progress notifications throughout the speech generation process:

1. **Model Loading Phase:**
   - "Loading Chatterbox TTS model..."
   - "Initializing PyTorch device..."
   - "Loading model weights..."
   - "Model loaded successfully!"

2. **Speech Generation Phase:**
   - "Starting speech generation..."
   - "Speech generated, saving to temporary file..."

3. **Playback Phase:**
   - "Playing audio..."
   - "Audio playback completed!"

4. **Stat…
