QRX MCP server

QRX

Art QR codes that always scan.

QRX makes branded, print-ready QR codes for posters, menus, packaging and signage. Describe the look you want and give it a link: QRX paints the code into artwork, checks that it decodes before handing it over, and points it at a hosted short link, https://qrx.to/ on qrx.codes, that you can re-point later on the Starter plan. This repository connects QRX to Claude, ChatGPT, Cursor, VS Code and other MCP clients through the remote server at https://qrx.codes/mcp.

Listed in the official MCP Registry as codes.qrx/mcp.

The QRX logo is a QRX code. Point your phone at it.

What you can do

• Make a code: "Make a QR code for https://example.com/menu that looks like a watercolour café street."
• Check on it: generation usually takes under a minute; the agent waits for it and returns the image and short link.
• Find old codes: list the codes on your account, newest first.
• Re-point a code: send an existing printed code to a new link, with no reprint (Starter plan).
• Check your allowance: see how many codes you have left today.

Connection details

Sign in or use an API key

Every client below that takes a URL signs in with your QRX account: add the URL, then sign in (free) when the client asks as it connects. There is nothing to copy or keep secret.

For clients that only run local servers, and for scripts and CI, use an API key. Any client below can use one instead of signing in:

1. Sign in at qrx.codes (free).
2. Open qrx.codes/developers/keys and create a key. It starts with qrx_.
3. Keep it secret. The examples below read it from an environment variable called QRXAPIKEY wherever the client allows that:

# macOS / Linux
   export QRX_API_KEY="qrx_live_…"

# Windows PowerShell (current user, persistent)
   [Environment]::SetEnvironmentVariable("QRX_API_KEY", "qrx_live_…", "User")
