Minimax MCP Tools

A Model Context Protocol (MCP) server implementation with Minimax API integration for AI-powered image generation and text-to-speech functionality.

English | 简体中文

Features

• Image Generation: Generate high-quality images based on text prompts using Minimax’s image-01 model
• Text-to-Speech (TTS): Convert text to natural-sounding speech with various voice options, emotions, and audio formats

Setup

Prerequisites

• Node.js 16 or higher
• A Minimax API key (obtain from Minimax Platform)
• Minimax Group ID for TTS functionality

Configuration

Create or update your MCP configuration file:

{
  "mcpServers": {
    "minimax-mcp-tools": {
      "command": "npx",
      "args": [
        "minimax-mcp-tools"
      ],
      "env": {
        "MINIMAX_API_KEY": "your-minimax-api-key",
        "MINIMAX_GROUP_ID": "your-minimax-group-id"
      }
    }
  }
}

MCP Interface

Image Generation

Generate images based on text prompts:

// Example parameters for image generation
{
  "prompt": "A mountain landscape at sunset",
  "aspectRatio": "16:9",
  "n": 1,
  "outputFile": "/absolute/path/to/image.jpg",
  "subjectReference": "/path/to/reference.jpg" // Optional: local file or URL
}

Parameters:

• prompt (required): Description of the image to generate
• outputFile (required): Absolute path to save the generated image file. The directory must already exist. When generating multiple images (n>1), files will be named with sequential numbers (e.g., ‘image-1.jpg’, ‘image-2.jpg’).
• aspectRatio (optional): Aspect ratio of the image (default: “1:1”, options: “1:1”, “16:9”, “4:3”, “3:2”, “2:3”, “3:4”, “9:16”, “21:9”)
• n (optional): Number of images to generate (default: 1, range: 1-9). When n>1, the output filenames will be automatically numbered.
• subjectReference (optional): Path to a local image file or a public URL for character reference. When provided, the generated image will use this as a reference for character appearance. Supported formats: JPG, JPEG, PNG

Text-to-Speech

Convert text to speech with various customization options:

// Example parameters for text-to-speech
{
  "text": "Hello, this is a test of the text-to-speech functionality.",
  "model": "speech-02-hd",
  "voiceId": "female-shaonv",
  "speed": 1.0,
  "volume": 1.0,
  "pitch": 0,
  "emotion": "happy",
  "format": "mp3",
  "outputFile": "/absolute/path/to/audio.mp3",
  "subtitleEnable": true
}

Basic Parameters:

• text (required): Text to convert to speech (max 10,000 characters)
• outputFile (required): Absolute path to save the generated audio file
• model (optional): Model version to use (default: “speech-02-hd”, options: “speech-02-hd”, “speech-02-turbo”)
  • speech-02-hd: High-definition model with excellent timbre similarity, rhythm stability, and studio-grade audio quality
  • speech-02-turbo: Fast model with excellent performance and low latency, enhanced multilingual capabilities
• voiceId (optional): Voice ID to use (default: “male-qn-qingse”)
• speed (optional): Speech speed (default: 1.0, range: 0.5-2.0)
• volume (optional): Speech volume (default: 1.0, range: 0.1-10.0)
• pitch (optional): Speech pitch (default: 0, range: -12 to 12)
• emotion (optional): Emotion of the speech (default: “neutral”, options: “happy”, “sad”, “angry”, “fearful”, “disgusted”, “surprised”, “neutral”)
• timberWeights (optional): Voice mixing settings, allows mixing up to 4 different voices with weights

  "timberWeights": [
    { "voice_id": "male-qn-qingse", "weight": 70 },
    { "voice_id": "female-shaonv", "weight": 30 }
  ]
  

Audio Settings:

• format (optional): Audio format (default: “mp3”, options: “mp3”, “pcm”, “flac”, “wav”)
• sampleRate (optional): Sample rate in Hz (default: 32000, options: 8000, 16000, 22050, 24000, 32000, 44100)
• bitrate (optional): Bitrate for MP3 format (default: 128000, options: 32000, 64000, 128000, 256000)
• channel (optional): Number of audio channels (default: 1, options: 1=mono, 2=stereo)

Advanced Features:

• latexRead (optional): Whether to read LaTeX formulas (default: false)
• pronunciationDict (optional): List of pronunciation replacements

  "pronunciationDict": ["处理/(chu3)(li3)", "危险/dangerous"]
