Installation

Installing via Smithery

To install MiniMax MCP JS for Claude Desktop automatically via Smithery:

npx -y @smithery/cli install @MiniMax-AI/MiniMax-MCP-JS --client claude

Installing manually

# Install with pnpm (recommended)
pnpm add minimax-mcp-js

Quick Start

MiniMax MCP JS implements the Model Context Protocol (MCP) specification and can be used as a server to interact with MCP-compatible clients (such as Claude AI).

Quickstart with MCP Client

1. Get your API key from MiniMax International Platform.

2. Make sure that you already installed Node.js and npm

3. Important: API HOST&KEY are different in different region, they must match, otherwise you will receive an Invalid API key error.

Using with MCP Clients (Recommended)

Configure your MCP client:

Claude Desktop

Go to Claude > Settings > Developer > Edit Config > claude_desktop_config.json to include:

{
  "mcpServers": {
    "minimax-mcp-js": {
      "command": "npx",
      "args": [
        "-y",
        "minimax-mcp-js"
      ],
      "env": {
        "MINIMAX_API_HOST": "",
        "MINIMAX_API_KEY": "",
        "MINIMAX_MCP_BASE_PATH": "",
        "MINIMAX_RESOURCE_MODE": ""
      }
    }
  }
}

Cursor

Go to Cursor → Preferences → Cursor Settings → MCP → Add new global MCP Server to add the above config.

⚠️ Note: If you encounter a "No tools found" error when using MiniMax MCP JS with Cursor, please update your Cursor to the latest version. For more information, see this discussion thread.

That's it. Your MCP client can now interact with MiniMax through these tools.

For local development:

When developing locally, you can use npm link to test your changes:

# In your project directory
npm link

Then configure Claude Desktop or Cursor to use npx as shown above. This will automatically use your linked version.

⚠️ Note: The API key needs to match the host address. Different hosts are used for global and mainland China versions:

• Global Host: https://api.minimaxi.chat (note the extra "i")
• Mainland China Host: https://api.minimaxi.chat

Transport Modes

MiniMax MCP JS supports three transport modes:

Configuration

MiniMax-MCP-JS provides multiple flexible configuration methods to adapt to different use cases. The configuration priority from highest to lowest is as follows:

1. Request Parameter Configuration (Highest Priority)

In platform hosting environments (like ModelScope or other MCP platforms), you can provide an independent configuration for each request via the meta.auth object in the request parameters:

{
  "params": {
    "meta": {
      "auth": {
        "api_key": "your_api_key_here",
        "api_host": "",
        "base_path": "/path/to/output",
        "resource_mode": "url"
      }
    }
  }
}

This method enables multi-tenant usage, where each request can use different API keys and configurations.

2. API Configuration

When used as a module in other projects, you can pass configuration through the startMiniMaxMCP function:

import { startMiniMaxMCP } from 'minimax-mcp-js';

await startMiniMaxMCP({
  apiKey: 'your_api_key_here',
  apiHost: 'https://api.minimaxi.chat', // Global Host - https://api.minimaxi.chat, Mainland Host - https://api.minimax.chat
  basePath: '/path/to/output',
  resourceMode: 'url'
});

3. Command Line Arguments

1. Install the CLI tool globally:

# Install globally
pnpm install -g minimax-mcp-js

2. When used as a CLI tool, you can provide configuration via command line arguments:

minimax-mcp-js --api-key your_api_key_here --api-host https://api.minimaxi.chat --base-path /path/to/output --resource-mode url

4. Environment Variables (Lowest Priority)

The most basic configuration method is through environment variables:

# MiniMax API Key (required)
MINIMAX_API_KEY=your_api_key_here

# Base path for output files (optional, defaults to user's desktop)
MINIMAX_MCP_BASE_PATH=~/Desktop

# MiniMax API Host (optional, defaults to https://api.minimaxi.chat, Global Host - https://api.minimaxi.chat, Mainland Host - https://api.minimax.chat)
MINIMAX_API_HOST=https://api.minimaxi.chat

# Resource mode (optional, defaults to 'url')
# Options: 'url' (return URLs), 'local' (save files locally)
MINIMAX_RESOURCE_MODE=url

Configuration Priority

When multiple configuration methods are used, the following priority order applies (from highest to lowest):

1. Request-level configuration (via meta.auth in each API request)

2. Command line arguments

3. Environment variables

4. Configuration file

5. Default values

This prioritization ensures flexibility across different deployment scenarios while maintaining per-request configuration capabilities for multi-tenant environments.

Configuration Parameters

⚠️ Note: The API key needs to match the host address. Different hosts are used for global and mainland China versions:

• Global Host: https://api.minimaxi.chat (note the extra "i")
• Mainland China Host: https://api.minimax.chat

Example usage

⚠️ Warning: Using these tools may incur costs.

1. broadcast a segment of the evening news

2. clone a voice

3. generate a video

4. generate images

5. generate music

6. voice design
