QR codes are a good fit for an AI assistant: the task is small, the
input is a URL, and the output is an image. This tutorial connects
Claude (or ChatGPT) to qrlia,
a QR code platform with a remote MCP server, and walks through creating,
updating and tracking a code.
Disclosure: I built qrlia.
No API key is needed. The server uses OAuth 2.1: you sign in in the
browser and approve access.
https://mcp.qrlia.com/mcp
qrlia.read, qrlia.write, and an opt-in
qrlia.admin for workspace admins)
qrlia is in the Claude connector directory:
https://claude.ai/directory/connectors/qrlia
In ChatGPT, open Settings → Apps, turn on developer mode under
Advanced, and create an app with the URL https://mcp.qrlia.com/mcp.
ChatGPT opens the qrlia sign-in; approve access. Your ChatGPT plan
needs to support custom apps.
claude mcp add --transport http qrlia https://mcp.qrlia.com/mcp
Then, inside Claude Code:
/mcp
Select qrlia and sign in in the browser window that opens. Add
--scope user to the add command if you want it in every project.
Add the server to your client's MCP config. For Cursor
(~/.cursor/mcp.json):
{
"mcpServers": {
"qrlia": {
"url": "https://mcp.qrlia.com/mcp"
}
}
}
Cursor will prompt you to sign in. Configs for other clients are in
https://github.com/mgazelle/qrlia-mcp.
Create a QR code for https://example.com called Spring flyer and show
me the image.
Claude calls a create tool, then fetches the image (PNG or SVG) and
shows it. The code is dynamic: it encodes a short link, and the short
link redirects to your URL.
You printed 500 flyers and the page moved:
Change the Spring flyer code to point to https://example.com/summer.
The printed code stays the same. Only the redirect changes.
Show scan analytics for the last 30 days: which codes were scanned
most, and from which countries?
On the free plan you get scan totals. Pro adds breakdowns by day,
country, city, device, OS and referrer.
On a paid plan you can describe your brand and let the assistant save
it as a design:
Save a design called Brand: dark red #7C220D modules, blue #00AEEF
corner markers, rounded dots, our logo from
https://example.com/logo.png in the centre, and a banner frame that
says "Scan to save my contact". Then apply it to the Spring flyer code.
Every code that uses the design follows it, and editing the design
updates them all. Without your own logo, codes show the qrlia mark; you
can also ask for no logo at all.
The same operations are in a REST API with OpenAPI docs at
https://docs.qrlia.com (Pro plan). MCP and REST share one service
layer, so they behave the same.
That's the whole setup: one URL, one sign-in. If you try it, tell me
which prompts work badly; that's what I'm tuning next.
