minimax-omni

English | 简体中文

minimax-omni is a comprehensive Python package that provides both a powerful Command Line Interface (CLI) and a Model Context Protocol (MCP) server for interacting with MiniMax's diverse multimodal generation models.

Features

• Text-to-Speech (TTS): Generate high-quality speech with various voices, emotions, and speeds.
• Voice Clone & Design: Clone existing voices from audio files or design new voices using prompts.
• Text-to-Image: Generate high-resolution images from text prompts with customizable aspect ratios.
• Video Generation (Hailuo): Create videos from text, and optionally a first frame image.
• Music Generation: Create custom music tracks from text prompts and lyrics.
• MCP Server Support: Seamlessly integrate with any applications supporting the Model Context Protocol (MCP).

Installation

Requires Python >= 3.10.

pip install minimax-omni

Or install with CLI dependencies:

pip install "minimax-omni[cli]"

Configuration

Configuration is resolved in this priority order: CLI flag > environment variable > momni config set file.

Option 1 — momni config set (recommended for local use)

momni config set --api-key YOUR_KEY --api-host https://api.minimax.chat

Settings are saved to ~/.config/minimax/config.json. Run momni config doctor to verify.

Option 2 — .env file

Copy .env.example to .env in your working directory and fill in the values:

MINIMAX_API_KEY=your_key
MINIMAX_API_HOST=https://api.minimax.chat
# MINIMAX_MCP_BASE_PATH=~/Desktop
# MINIMAX_API_RESOURCE_MODE=local

Option 3 — Environment variables

Variable	Required	Default	Description
MINIMAX_API_KEY	✅	—	Your MiniMax API key
MINIMAX_API_HOST	✅	—	https://api.minimax.chat (China) or https://api.minimaxi.chat (Global)
MINIMAX_MCP_BASE_PATH	—	~/Desktop	Output directory when using local mode
MINIMAX_API_RESOURCE_MODE	—	url	url returns a link; local saves to disk

CLI Usage

The package provides two CLI commands: minimax-omni and momni as a shortcut.

Voice Generation

# Text-to-Speech
momni tts "Hello world!" --voice-id female-shaonv --model speech-2.6-hd

# List available voices
momni voice list

# Clone a voice
momni voice clone <voice_id> <path_to_audio_file> <text>

# Voice design
momni voice design "An enthusiastic female voice" "This is a preview text"

Image and Video Generation

# Generate Image
momni image "A futuristic city under a starry night" --aspect-ratio 16:9

# Generate Video
momni video "A camera flying through a futuristic city"

# Check Video Status
momni video-status <task_id>

Music Generation

momni music "lo-fi chill beats" "Soft wind blowing through the trees..."

MCP Server Usage

You can use the built-in serve command to start the MCP server, which exposes these generation endpoints as tools via the standard MCP interface:

momni serve

Example configuration for an MCP client:

{
  "mcpServers": {
    "minimax-omni": {
      "command": "momni",
      "args": ["serve"],
      "env": {
        "MINIMAX_API_KEY": "your_api_key",
        "MINIMAX_API_HOST": "https://api.minimax.chat"
      }
    }
  }
}
