MCP setup · Claude Desktop

Connect MyQRx to Claude Desktop.

The Claude app for Mac and Windows. With MyQRx connected, it can make dynamic QR codes in your account, change where they point after printing and tell you which one worked.

Step 1

Get an API token.

Sign in to MyQRx (Free works), open Settings → API tokens, name it "Claude Desktop" and tick what it may do. Copy the token: it is shown once.

Step 2

Add the server.

Claude Desktop connects to remote servers through a small bridge, mcp-remote, which needs Node.js. Add this to claude_desktop_config.json (Settings → Developer → Edit Config). Replace mqx_your_token with your token.

{
  "mcpServers": {
    "myqrx": {
      "command": "npx",
      "args": ["-y", "mcp-remote", "https://myqrx.com/mcp", "--header", "Authorization: Bearer mqx_your_token"]
    }
  }
}

Step 3

Check it works.

1
Install Node.js if you don't have it (node --version should print a version).
2
Paste the configuration into claude_desktop_config.json and restart Claude Desktop.
3
Check the tools icon lists the MyQRx tools, then ask: "List my MyQRx QR codes."

Then ask

Things to try in Claude Desktop.

"Make a dynamic QR code for each of our 3 stores, pointing to example.com/offer, named by store."

"Show me the QR code for the Andheri store so I can check it."

"Which store's code got the most scans this month, and is that up on last month?"

"Point the weakest store's code at example.com/new-offer."

A dynamic code uses one slot of your plan's quota; static codes (Wi-Fi, vCard, plain text) are unlimited. Which to choose.

If something's off

Fixes for Claude Desktop.

MyQRx doesn't appear after a restart

Quit Claude Desktop fully (not just the window), and check the config file is valid JSON.

"npx: command not found"

Node.js is not installed or not on your PATH. Install it from nodejs.org and restart Claude Desktop.

An error says quota_exceeded

Your plan's dynamic codes are used up. Static codes still work; upgrade or buy a code pack for more.

An error says missing_ability

The token can't do that. Create a token with that ability ticked and use it instead.
