How do I connect QRBold to Claude?

In Claude.ai open Settings → Connectors, click Add custom connector, paste https://api.qrbold.com/mcp as the server URL and click Add. Then click Connect: a QRBold page opens, you sign in and click Allow. Claude can now create QR codes and digital business cards in your account.

Before you start, you need two things

1. A QRBold account

Free is fine. Create one here if you don’t have one. The assistant connection is included on every plan.

2. A Claude plan with connectors

Custom connectors are a feature of Claude’s paid plans. On a Team or Enterprise plan an admin may need to allow them. No paid Claude plan? Use Claude Code instead.

Claude.ai in the browser

Six small steps. The pictures show what each screen looks like and where to click.

  1. 1

    Copy the QRBold link

    Click Copy. That is the whole address of QRBold’s assistant connection. You will paste it in step 3.

    In Claude, open Settings, then Connectors

    Click your name or initials at the bottom-left of Claude, choose Settings, then click Connectors in the list.

    You will see a list of ready-made connectors. Scroll to the bottom of that list.

    Sign in to QRBold and click Allow

    If you are not already signed in, sign in the normal way. You will then see a page that says Claude wants to access your QRBold account, with a short list of what it will be able to do.

    Click Allow. The tab closes or sends you back to Claude, where QRBold now says Connected.

    You only do this once. Claude stays connected until you disconnect it.

    Start a chat and ask

    Open a new chat. If QRBold is not used automatically, click the + (tools) button under the message box and make sure QRBold is switched on.

    Then just ask, in your own words. Claude shows you the result in the chat, and it also appears in your QRBold dashboard.

    Not sure what to ask? Here are 40+ prompts.

    Make a QR code for https://acme.com/spring-sale and name it “Spring sale poster”.

    Used QRBold · create_qr_code

    Created “Spring sale poster” in QRBold, pointing to acme.com/spring-sale. It’s dynamic, so you can change the link later. Here is the code:

Claude Desktop

Two options — the first one is the easy one.

  1. 1

    Easiest: use the same Settings → Connectors

    Claude Desktop uses the same connectors as Claude.ai. If you followed the steps above, open the desktop app and QRBold is already there. If not, open Settings → Connectors in the desktop app and do steps 3 to 5 from above.

    Connected click
  2. 2

    Alternative: a config file (no paid plan needed)

    Open Settings → Developer → Edit Config. This opens a file called claude_desktop_config.json. Paste the snippet on the right (or add the qrbold entry to your existing mcpServers), save, and restart Claude Desktop.

    The first time you use it, a browser tab opens on qrbold.com asking you to sign in and click Allow. This route needs Node.js 18 or newer on your computer.

    claude_desktop_config.json
    {
  "mcpServers": {
    "qrbold": {
      "command": "npx",
      "args": ["-y", "mcp-remote", "https://api.qrbold.com/mcp"]
    }
  }
}

Claude Code (terminal)

One command, then sign in.

  1. 1

    Add the server

    Run the command on the right in your project folder. Add --scope user if you want it in every project.

    Terminal
    claude mcp add --transport http qrbold https://api.qrbold.com/mcp
  2. 2

    Sign in

    Start Claude Code, type /mcp, choose qrbold and press Authenticate. Your browser opens on qrbold.com; sign in and click Allow. Back in the terminal, QRBold shows as connected.

    Now you can say things like “create a QR code for the staging URL and drop the SVG in /public”.

    Claude Code

  → select qrbold → Authenticate

If something does not work

What you seeWhat to do
Claude answers without using QRBoldOpen the tools menu in the chat (the + button) and switch QRBold on for that conversation. Then ask again, naming QRBold if you like: “Using QRBold, create…”.
The connector shows “Connect” againYour approval was removed or expired. Click Connect, sign in, click Allow. It takes 20 seconds.
“Request expired” on the QRBold pageThe Allow page is only valid for 10 minutes. Go back to Claude and click Connect again.
“Connection failed” right after AllowUsually a network hiccup during the last step. Remove the QRBold connector in Claude and add it again.
Claude says I am over my limitYour QRBold plan has a maximum number of QR codes or cards. Free one up in the dashboard or upgrade — the assistant uses the same limits.

How to disconnect

In QRBold, open Settings → Developer API → Connected apps and click Disconnect next to Claude. That ends Claude’s access straight away (it may finish a request it already started, for up to one hour). You can also remove the connector inside Claude — but the QRBold side is the one that really cuts the cord.
