The same snippet works in Cursor. Requires uv.

This is third-party code. Review the repository files before installing.

What it does

The server connects the agent to the MiniMax API with tools to voice text with a chosen voice, list voices, clone a voice from audio and design a voice from a description. It also generates images from prompts and videos, including the Hailuo-02 model, with a separate tool to poll generation status. Results come back as URLs or are saved to a local folder. It runs over stdio or SSE.

Who it is for. For content creators and developers who need voiceover, images and video straight from the agent.

Good fit when

  • You need to voice a text or create a voice from a description
  • You need a short video or an image from a prompt
  • You need to clone a voice from a sample recording

Not a fit when

  • You have no MiniMax account or budget for paid calls
  • Audio and text must not go to a third-party service

Example request

Voice this paragraph with a calm male voice and save the file to my desktop

Limitations

Requires a MiniMax API key and calls are paid. The key and API host must belong to the same region or you get invalid api key. Requires uv. The authors now recommend their mmx-cli as the primary tool. API availability from Russia without a VPN is unverified.

How to disable. Remove the MiniMax block from claude_desktop_config.json or Cursor's MCP settings.

  • Writes files to a local folder

README in short

The README shows setup for Claude Desktop and Cursor through uvx and explains regional keys and hosts. It lists voice, image and video tools, describes stdio and SSE transports and URL or local file output. It warns that calls cost money and points to mmx-cli as the newer option. MIT licensed.

FAQ

How to fix invalid api key?

Make sure the key and host are from the same region: global api.minimax.io or mainland api.minimaxi.com.

The client reports spawn uvx ENOENT

Find the full path with which uvx and put it in the command field.
