Install @coretext-ai/test-this-out-f702d4f7-d880-430e-a93d-dd3256e5bd3f in Devin Desktop

What you need first

• Devin Desktop, installed.
• Node.js, which gives the npx command the server starts with.

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": {
    "test-this-out": {
      "command": "npx",
      "args": ["-y", "@coretext-ai/test-this-out-f702d4f7-d880-430e-a93d-dd3256e5bd3f"]
    }
  }
}

3. Save the file and restart Devin Desktop.

Check it worked

Ask Devin Desktop: List the tools of test-this-out.

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.

Nothing changes after a restart

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