MiniMax Unified MCP

⚡ Unified MiniMax MCP for multimodal generation, Token Plan search, and image understanding.

English | 简体中文

</div>

✨ Overview

minimax-unified-mcp merges three capability groups into one installable MCP server:

• Official multimodal MiniMax generation tools
• Official Token Plan tools: web_search and understand_image
• Token Plan quota lookup aligned with the ExoMind Team workflow

This repository is intended for local-first MCP usage in Claude, Codex, and compatible MCP clients.

🧰 Tools

Tool	Purpose
quota_tool	Query Token Plan quota and refresh window
web_search_tool	Search the live web via Token Plan
understand_image_tool	Analyze a local image path, remote URL, or data: URL
text_to_audio_tool	Generate speech with configurable output mode
text_to_audio_streaming_tool	Low-latency speech playback path
list_voices_tool	List available voices
voice_clone_tool	Clone a voice from sample audio
play_audio_tool	Play local or remote audio
generate_video_tool	Generate text-to-video or image-to-video
query_video_generation_tool	Query video generation status
text_to_image_tool	Generate images
music_generation_tool	Generate music from prompt and lyrics
voice_design_tool	Design a new voice

🚀 Quick Start

1. Install

cd path/to/minimax-unified-mcp
python -m pip install -e ".[dev]"

2. Configure environment

Copy .env.example to .env and fill in your credentials.

Important variables:

• MINIMAX_TOKEN_PLAN_API_KEY: Token Plan API key
• MINIMAX_API_HOST: https://api.minimax.io or https://api.minimaxi.com
• MINIMAX_MCP_BASE_PATH: base path for local artifacts
• MINIMAX_API_RESOURCE_MODE: url or local
• FASTMCP_LOG_LEVEL: logging level, usually WARNING or INFO

3. Add to your MCP client

{
  "mcpServers": {
    "MiniMaxUnified": {
      "command": "python",
      "args": ["-m", "exomind_minimax_mcp"],
      "env": {
        "MINIMAX_TOKEN_PLAN_API_KEY": "YOUR_TOKEN_PLAN_KEY",
        "MINIMAX_API_HOST": "https://api.minimax.io",
        "MINIMAX_MCP_BASE_PATH": "./output/minimax",
        "MINIMAX_API_RESOURCE_MODE": "local",
        "FASTMCP_LOG_LEVEL": "WARNING"
      }
    }
  }
}

See mcp_server_config_demo.json for a ready-to-copy example.

🧭 Recommended Usage

Web search

Use web_search_tool for current external information.

{
  "query": "MiniMax Token Plan latest image model"
}

Image understanding

Follow the official Token Plan MCP signature: prompt + image_source.

image_source supports:

• local file path, such as D:/images/demo.png
• HTTP / HTTPS image URL
• data: URL

{
  "prompt": "Describe the UI structure in this screenshot",
  "image_source": "D:/images/screenshot.png"
}

Image generation then image understanding

1. Call text_to_image_tool
2. Copy one returned image URL
3. Pass that URL into understand_image_tool.image_source

Low-latency TTS

Prefer text_to_audio_streaming_tool when perceived latency matters.

{
  "text": "hello from MiniMax"
}

Use text_to_audio_tool when you need more control over resource_mode, local output, or autoplay.

Quota field notes

quota_tool currently maps the upstream fields to their display semantics as follows:

• current_interval_usage_count: remaining in current interval（当前窗口剩余）
• current_weekly_usage_count: weekly remaining（本周剩余）

Note: even though the field name contains usage_count, this output is treated as remaining quota, not used quota.

Video generation

• Default text-to-video path uses MiniMax-Hailuo-2.3
• If you choose MiniMax-Hailuo-2.3-Fast, also provide first_frame_image
• first_frame_image supports local path, URL, or data: URL

{
  "prompt": "A cute orange cat sleeping in sunlight",
  "model": "MiniMax-Hailuo-2.3-Fast",
  "first_frame_image": "D:/images/cat.png",
  "async_mode": true
}

Music generation

Music generation is slower than typical text APIs. The unified client uses an extended request timeout for this endpoint, but real latency still depends on upstream service status.

📦 Output Modes

Two output modes are supported:

• url: return remote URLs directly
• local: download artifacts to MINIMAX_MCP_BASE_PATH

Use local when you want reproducible local files for downstream automation.

🛡️ Errors and Quota Signals

The unified client preserves upstream errors and improves readability for common account states:

• 1008 insufficient balance: clearly reported as balance insufficient
• 2056 usage limit exceeded: clearly reported as quota / usage exhausted
• 2013 invalid params: preserved for bad payloads such as unsupported video mode combinations

✅ Testing

Run the full suite:

python -m pytest -v

Run the live API matrix:

python scripts/run_live_api_matrix.py --json

The live matrix classifies results into statuses such as passed, unsupported, insufficient_balance, usage_limit_exceeded, timeout, and invalid_params.

📌 Status

The package runs from src/exomind_minimax_mcp/ and no longer depends on uvx for local development. It is ready for GitHub-based release packaging and ongoing MCP client integration.
