Install LFM2.5 2.6B Heretic in Devin Desktop

What you need first

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

Steps

1. Open ~/.config/devin/mcp_config.json, or create it. On Windows it is %APPDATA%\devin\mcp_config.json.
2. Add this block. If the file already has mcpServers, add only the entry inside it.

{
  "mcpServers": {
    "lfm2-5-2-6b-heretic": {
      "url": "https://vampelium-lfm2-5-2-6b-heretic.hf.space/gradio_api/mcp/sse"
    }
  }
}

3. Save the file and restart Devin Desktop.

Check it worked

Ask Devin Desktop: List the tools of lfm2-5-2-6b-heretic. It should list 1 tool.

If it does not start

401 Unauthorized

The endpoint wants a sign-in or a key. Sign in when Devin Desktop asks.

Nothing changes after a restart

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