MCP Server for Alibaba Cloud CosyVoice

CosyVoice MCP Server

A Model Context Protocol (MCP) server for Alibaba Cloud's CosyVoice 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:

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.

export COSYVOICE_DEFAULT_OUTPUT_DIR=~/Desktop/CosyVoiceOutput
