MiniMax MCP JS

MiniMax MCP JS is an MCP server that provides access to MiniMax generative AI capabilities directly inside Model Context Protocol environments. It connects clients like Claude Desktop and Cursor to MiniMax services for image generation, video creation, text-to-speech conversion, voice cloning, and custom voice design. Software developers, creative technologists, and content creators use this server to automate multimedia asset creation through standard agent tool calls. The integration allows assistants to trigger the MiniMax-Hailuo-02 model to produce videos with defined durations and resolutions, generate custom audio with subtitle files, and synthesize personalized voices from natural language prompts. Operating over stdio, REST, or Server-Sent Events, the server supports local command-line workflows alongside cloud deployments. It accepts dynamic configuration through request parameters, JavaScript API options, CLI flags, or environment variables, allowing users to direct generated outputs to local storage or external URLs while handling region-specific API endpoints across global and mainland deployments.

How to install and configure MiniMax MCP JS

1. Obtain an API key from the MiniMax platform matching your region (Global: https://api.minimaxi.chat or Mainland China: https://api.minimax.chat). 2. Open your client configuration file, such as claude_desktop_config.json in Claude Desktop. 3. Add the server entry under mcpServers using npx: json { "mcpServers": { "minimax-mcp-js": { "command": "npx", "args": ["-y", "minimax-mcp-js"], "env": { "MINIMAX_API_HOST": "https://api.minimaxi.chat", "MINIMAX_API_KEY": "<your-api-key-here>", "MINIMAX_MCP_BASE_PATH": "/path/to/desktop", "MINIMAX_RESOURCE_MODE": "url" } } } } 4. Alternatively, install automatically for Claude Desktop using Smithery by running npx -y @smithery/cli install @MiniMax-AI/MiniMax-MCP-JS --client claude.

What you can do with MiniMax MCP JS

• Creating custom synthetic voices by providing descriptive natural language prompts to the voice design tool. - Generating high-resolution videos using the MiniMax-Hailuo-02 model with 6s or 10s duration controls. - Converting written text into spoken audio files while extracting synchronized subtitle transcripts automatically. - Producing AI-generated images directly within coding editors using conversational prompts sent to MiniMax models. - Cloning specific vocal profiles to generate consistent character speech across multimedia development pipelines.

How do I install MiniMax MCP JS?

You can install MiniMax MCP JS automatically for Claude Desktop using Smithery via the command npx -y @smithery/cli install @MiniMax-AI/MiniMax-MCP-JS --client claude. Alternatively, add the server to your Claude Desktop or Cursor configuration file using npx with the minimax-mcp-js package, or install it locally via pnpm add minimax-mcp-js.

What can MiniMax MCP JS do?

MiniMax MCP JS enables your MCP client to perform text-to-speech audio synthesis, subtitle generation, text-to-image creation, and video generation using models like MiniMax-Hailuo-02. It also provides tools for custom voice design based on text prompts and voice cloning capabilities.

Which MCP clients work with MiniMax MCP JS?

MiniMax MCP JS is compatible with standard MCP clients including Claude Desktop and Cursor. It also supports integration into custom applications using standard I/O, REST, or SSE transport modes, as well as platform hosting environments like ModelScope.

Why do I get an Invalid API key error?

The API key must match the specific API host assigned to your region. For MiniMax Global, set the host to https://api.minimaxi.chat with a key from the global platform. For Mainland China, set the host to https://api.minimax.chat with a key from the mainland platform. Mismatched hosts and keys cause authorization failures.

Is MiniMax MCP JS open source?

Yes, MiniMax MCP JS is open source and licensed under the MIT License. The complete source code is available in its GitHub repository.
