Install FLUX.2 Klein multi-LoRA in Gemini CLI

What you need first

• Gemini CLI, installed.
• Nothing else: the server runs on its publisher's machines and Gemini CLI connects to it.

Steps

1. Open ~/.gemini/settings.json, or create it. For one project only, use .gemini/settings.json in that project.
2. Add this block. If the file already has mcpServers, add only the entry inside it.

{
  "mcpServers": {
    "flux-2-klein-multi-lora": {
      "url": "https://masterp3000-flux-2-klein-multi-lora.hf.space/gradio_api/mcp/sse"
    }
  }
}

3. Save the file and restart Gemini CLI.

Check it worked

Ask Gemini CLI: List the tools of flux-2-klein-multi-lora. It should list 7 tools.

If it does not start

401 Unauthorized

The endpoint wants a sign-in or a key. Sign in when Gemini CLI asks.

Nothing changes after a restart

The file is not valid JSON any more. Look for a missing comma where the block was added.
