Install md-vision in Devin Desktop

What you need first

• Devin Desktop, installed.
• Node.js, which gives the npx command the server starts with.
• Your own values for YOUR_ALLOW_PATH,YOUR_ALLOW_DOMAIN.

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": {
    "md-vision": {
      "command": "npx",
      "args": ["-y", "[email protected]", "--allow-path", "YOUR_ALLOW_PATH", "--allow-domain", "YOUR_ALLOW_DOMAIN"]
    }
  }
}

3. Replace YOUR_ALLOW_PATH,YOUR_ALLOW_DOMAIN with your own values.
4. Save the file and restart Devin Desktop.

Check it worked

Ask Devin Desktop: List the tools of md-vision.

If it does not start

spawn npx ENOENT

Node.js is not on the PATH that Devin Desktop sees. Install it, or write the full path of npx in the config.

The server starts, but its tools fail

A YOUR_… placeholder is still in the config, or its value is wrong.

Nothing changes after a restart

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