How to Connect Libautech Upsell to Claude With MCP

Libautech: Bundles & Upsell speaks MCP, the open standard that lets Claude connect to outside tools. Once it is connected, you can ask Claude about your Shopify upsell offers in plain English, straight from the Claude desktop app, without opening a dashboard.
You can ask things like “how are my upsell offers performing this month?” or “what are my top performing upsell offers?” and Claude reads the answer from your live data. Setup takes about five minutes and you only do it once.
What you need
- The Claude desktop app for Mac or Windows. The claude.ai website and the phone app do not support this yet.
- Your Libautech Upsell access key. We send this to your store; it is private to you and we can disable it at any time.
Step 1. Install Claude Desktop
If you do not have it yet, download it from claude.ai/download, open it and sign in. The website and mobile apps cannot do this, so it has to be the computer app.
Step 2. Add the connection
In Claude Desktop, open Settings (the gear icon), click Developer in the left sidebar, then click Edit Config. A folder opens with a file called claude_desktop_config.json. Open that file in any text editor; a double-click usually works, and on Windows choose Notepad.
- If the file is empty or only contains
{}: select everything in it, delete it, and paste the block below. - If there is already other text in it: stop here and send us a screenshot of the file instead, and we will prepare the right version for you.

"--header",
"Authorization:${UPSELL_AUTH}"
],
"env": {
"UPSELL_AUTH": "Bearer PASTE_KEY_HERE"
}
}
}
}
Replace PASTE_KEY_HERE with the access key we sent you. Keep the word Bearer and the single space before the key. Save the file.
Step 3. Restart Claude Desktop completely
- Mac: press Cmd+Q with Claude focused, then reopen it.
- Windows: right-click the Claude icon in the system tray (bottom-right corner) and choose Quit, then reopen it.
Step 4. Check it worked
Open a new chat and click the small sliders icon near the message box. You should see libautech-upsell in the list of tools. Try asking: “What are my top performing upsell offers?”
If the connection does not appear after restarting, install Node.js from nodejs.org (the green LTS button, accept the defaults), restart Claude Desktop again, and it will show up. If anything else looks off, reply with a screenshot and we will sort it out together. The key is private to your store only, and we can disable it at any time.
