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.

|Region| Global | Mainland | |:--|:-----|:-----| |MINIMAX_API_KEY| go get from MiniMax Global | go get from MiniMax | |MINIMAX_API_HOST| ​https://api.minimaxi.chat (note the extra "i") | ​https://api.minimax.chat |

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": "<https://api.minimaxi.chat|https://api.minimax.chat>",
        "MINIMAX_API_KEY": "<your-api-key-here>",
        "MINIMAX_MCP_BASE_PATH": "<local-output-dir-path, such as /User/xxx/Desktop>",
        "MINIMAX_RESOURCE_MODE": "<optional, [url|local], url is default, audio/image/video are downloaded locally or provided in URL format>"
      }
    }
  }
}

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

MiniMax MCP JS supports three transport modes:

| Feature | stdio (default) | REST | SSE | |:-----|:-----|:-----|:-----| | Environment | Local only | Local or cloud deployment | Local or cloud deployment | | Communication | Via standard I/O | Via HTTP requests | Via server-sent events | | Use Cases | L
