Minimax MCP Tools

A Model Context Protocol (MCP) server for Minimax AI integration, providing async image generation and text-to-speech with advanced rate limiting and error handling.

MCP Configuration

Add to your MCP settings:

{
  "mcpServers": {
    "minimax-mcp-tools": {
      "command": "npx",
      "args": ["minimax-mcp-tools"],
      "env": {
        "MINIMAX_API_KEY": "your_api_key_here"
      }
    }
  }
}

Async Design - Perfect for Content Production at Scale

This MCP server uses an asynchronous submit-and-barrier pattern designed for batch content creation:

🎬 Narrated Slideshow Production - Generate dozens of slide images and corresponding narration in parallel
📚 AI-Driven Audiobook Creation - Produce chapters with multiple voice characters simultaneously
🖼️ Website Asset Generation - Create consistent visual content and audio elements for web projects
🎯 Multimedia Content Pipelines - Perfect for LLM-driven content workflows requiring both visuals and audio

Architecture Benefits:

Submit Phase: Tools return immediately with task IDs, tasks execute in background
Smart Rate Limiting: Adaptive rate limiting (10 RPM images, 20 RPM speech) with burst capacity
Barrier Synchronization: task_barrier waits for all tasks and returns comprehensive results
Batch Optimization: Submit multiple tasks to saturate rate limits, then barrier once for maximum throughput

Tools

`submit_image_generation`

Submit Image Generation Task - Generate images asynchronously.

Required: prompt, outputFile
Optional: aspectRatio, customSize, seed, subjectReference, style

`submit_speech_generation`

Submit Speech Generation Task - Convert text to speech asynchronously.

Required: text, outputFile
Optional: highQuality, voiceId, speed, volume, pitch, emotion, format, sampleRate, bitrate, languageBoost, intensity, timbre, sound_effects

`task_barrier`

Wait for Task Completion - Wait for ALL submitted tasks to complete and retrieve results. Essential for batch processing.
