How do I make a barcode in Claude?

Updated

Answer

You can ask Claude for your book's barcode in a chat. Add Barcode Rocket as a connector in Claude with the server address https://barcoderocket.com/mcp. Claude can check an ISBN, explain a price code and show a preview without an account; for the PDF you sign in once with your free Barcode Rocket account.

Steps

  1. In Claude, open Customize, then Connectors, click + Add and choose Add custom connector. On a Team or Enterprise plan, an Owner first adds it under Organization settings, then Connectors.
  2. Name it Barcode Rocket and enter the server URL https://barcoderocket.com/mcp. Under Authentication, choose Sign in when needed.
  3. Ask, for example: "Make me a KDP barcode for 9780306406157 at $19.99".
  4. The first time you ask for a PDF, Claude shows a Connect button. Sign in to Barcode Rocket (or create a free account) and choose Allow.
  5. Claude replies with a download link to the PDF. It works for 24 hours.
The Barcode Rocket page Let Claude make your book barcodes? with the signed-in email you@example.com, what Claude can and cannot do, and the buttons Cancel and Allow
Step 4: After you sign in, Barcode Rocket asks once. Click Allow.
