### Description (declared)

# CosyVoice MCP Server

A Model Context Protocol (MCP) server for Alibaba Cloud's [CosyVoice](https://help.aliyun.com/zh/model-studio/cosyvoice-voice-list) text-to-speech service.

This server allows you to generate high-quality, expressive speech from text using Alibaba Cloud's state-of-the-art CosyVoice models (V2 and V3).

## Features

- **List Voices**: Retrieve a curated list of high-quality voices suitable for various scenarios (social, narration, customer service, etc.).
- **Speech Synthesis**: Convert text to speech with support for:
    - **Model Selection**: Choose between `cosyvoice-v2` (standard) and `cosyvoice-v3-flash` (emotional).
    - **Control Parameters**: Adjust volume, speech rate, and pitch rate.
    - **Emotion Control**: Use natural language instructions to control emotion (V3 models only).
        - Supported emotions: `neutral`, `fearful`, `angry`, `sad`, `surprised`, `happy`, `disgusted`.
        - Format: `"你说话的情感是<emotion>。"`
    - **SSML Support**: Use SSML tags (e.g., `<break time="2s"/>`) for precise pause control.
    - **File Saving**: Save generated audio directly to a local file path.

## Configuration

You need an Alibaba Cloud DashScope API Key. Set it as an environment variable:

```bash
export COSYVOICE_MCP_DASHSCOPE_API_KEY=your_api_key_here
```

(Alternatively, `DASHSCOPE_API_KEY` is also supported).

### Optional Configuration

- `COSYVOICE_DEFAULT_OUTPUT_DIR`: Set a default directory for saving generated audio files if `output_file` is not specified.

```bash
export COSYVOICE_DEFAULT_OUTPUT_DIR=~/Desktop/CosyVoiceOutput
```

## MCP Client Configuration

Add the following to your MCP client configuration (e.g., `claude_desktop_config.json`):

### Using `uvx` (Recommended)

You can run the server directly from PyPI using `uvx`:

```json
{
  "mcpServers": {
    "cosyvoice": {
      "command": "uvx",
      "args": [
