MiniMax MCP

What is MiniMax MCP about?

MiniMax MCP provides a server that bridges MCP‑compatible clients (e.g., Claude Desktop, Cursor, Windsurf, OpenAI Agents) with MiniMax's AI services for speech synthesis, voice cloning, image creation, video generation, and music generation.

How to use MiniMax MCP?

1. Obtain an API key from the MiniMax platform (global or Mainland region).
2. Install the lightweight Python package manager uv (curl -LsSf https://astral.sh/uv/install.sh | sh).
3. Run the server with the command uvx minimax-mcp -y (or configure your MCP client to invoke this command).
4. Set required environment variables in the client configuration:
   • MINIMAX_API_KEY – your API key
   • MINIMAX_API_HOST – https://api.minimax.io (global) or https://api.minimaxi.com (Mainland)
   • Optional MINIMAX_MCP_BASE_PATH, MINIMAX_API_RESOURCE_MODE for local file handling.
5. Add the server configuration to the MCP client (e.g., Claude Desktop claude_desktop_config.json, Cursor MCP settings).

FAQ from MiniMax MCP

1. Invalid API key – Ensure the API key matches the selected host region (global vs. Mainland).
2. spawn uvx ENOENT – Verify uvx is in your PATH (which uvx) and use the absolute path in the client config.
3. Asynchronous video generation – Define completion rules before starting the task (see screenshots in the README) or configure them in IDE settings (e.g., Cursor).

Claude Desktop

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

{
  "mcpServers": {
    "MiniMax": {
      "command": "uvx",
      "args": [
        "minimax-mcp",
        "-y"
      ],
      "env": {
        "MINIMAX_API_KEY": "insert-your-api-key-here",
        "MINIMAX_MCP_BASE_PATH": "local-output-dir-path, such as /User/xxx/Desktop",
        "MINIMAX_API_HOST": "api host, https://api.minimax.io | https://api.minimaxi.com",
        "MINIMAX_API_RESOURCE_MODE": "optional, [url|local], url is default, audio/image/video are downloaded locally or provided in URL format"
      }
    }
  }
}

⚠️ Warning: The API key needs to match the host. If an error "API Error: invalid api key" occurs, please check your api host:

• Global Host：https://api.minimax.io
• Mainland Host：https://api.minimaxi.com

If you're using Windows, you will have to enable "Developer Mode" in Claude Desktop to use the MCP server. Click "Help" in the hamburger menu in the top left and select "Enable Developer Mode".

Cursor

Go to Cursor -> Preferences -> Cursor Settings -> MCP -> Add new global MCP Server to add above config.

FAQ

1. invalid api key

Please ensure your API key and API host are regionally aligned

Region	Global	Mainland
MINIMAX_API_KEY	go get from MiniMax Global	go get from MiniMax
MINIMAX_API_HOST	https://api.minimax.io	https://api.minimaxi.com

2. spawn uvx ENOENT

Please confirm its absolute path by running this command in your terminal:

which uvx

Once you obtain the absolute path (e.g., /usr/local/bin/uvx), update your configuration to use that path (e.g., "command": "/usr/local/bin/uvx").

3. How to use generate_video in async-mode

Define completion rules before starting: Alternatively, these rules can be configured in your IDE settings (e.g., Cursor):
