TheQRCode.io MCP Server

Generate QR codes — and read their scan analytics — from Claude, Cursor, or any MCP client.

Remote HTTP server. Nothing to install. No npm, no Docker, no Python. Point your client at one URL and ask.

https://mcp.theqrcode.io/mcp

Listed in the official MCP Registry as io.theqrcode/qr-code-generator.

Setup

Claude Desktop

Settings → Developer → Edit Config:

{
  "mcpServers": {
    "theqrcode": {
      "url": "https://mcp.theqrcode.io/mcp"
    }
  }
}

Cursor

~/.cursor/mcp.json:

{
  "mcpServers": {
    "theqrcode": {
      "url": "https://mcp.theqrcode.io/mcp"
    }
  }
}

With an API key (unlocks the analytics tools)

{
  "mcpServers": {
    "theqrcode": {
      "url": "https://mcp.theqrcode.io/mcp",
      "headers": {
        "Authorization": "Bearer YOUR_API_KEY"
      }
    }
  }
}

Any client supporting the MCP spec over streamable HTTP works. Restart the client after editing config, then just ask: "Generate a QR code for https://example.com".

Tools

Three tools. All three are advertised to every session — including anonymous ones, so directory crawlers see the real surface — but the two account tools refuse at call time without a key.

generate_qr_code — free, no key

Param	Type	Required	Notes
type	url | wifi | contact | text | email	yes	email requires a key
content	string	yes	the data to encode
name	string	no	display name when saving to an account
size	int 64–1024	no	default 256
darkColor	#RRGGBB	no	default #000000
lightColor	#RRGGBB	no	default #FFFFFF

Returns a hosted PNG URL plus a base64 data URL for inline display.

Anonymous → the public keyless API, 100 requests/hour per IP. The hosted link is a 24-hour preview; download the image rather than bookmarking the URL. The QR code itself never expires — it is the preview hosting that is temporary.

Authenticated → the v1 API. The code is saved to your account permanently, rate limited by key rather than IP, and email becomes available.

list_qr_codes — Developer plan

Lists codes saved to your account. page, limit (1–100), type filter.

get_analytics — Developer plan

Scan analytics, account-wide or for one qrCodeId. timeRange: 1h, 1d, 7d, 30d (default), 90d, 1y.

Returns total and unique scans, time, approximate location (country/city derived from IP — regional, not GPS), device and OS, and campaign. Static QR codes cannot be tracked; analytics require a dynamic code.

Running it yourself

The hosted server at mcp.theqrcode.io is the supported path — you do not need to run this. But it is a plain Express app if you want to:

npm install
npm run build
npm start          # or: npm run dev
npm test

Env	Default	Purpose
QR_API_BASE	https://theqrcode.io	REST API this server wraps
PORT	3001	listen port

Routes: POST|GET|DELETE /mcp (stateless — a fresh server and transport per request), GET /health.

Docker:

docker build -t theqrcode-mcp .
docker run -p 3001:3000 -e PORT=3000 theqrcode-mcp

What it wraps

TheQRCode.io is a QR code generation and analytics platform: static and dynamic QR codes for URLs, WiFi, vCard contacts and text, with scan analytics by time, device and approximate location. Static codes never expire, and printed codes are never switched off to force an upgrade.

This server is one of three ways in — the others are a keyless REST API and OpenAI function calling.

• Site — https://theqrcode.io
• REST API — https://theqrcode.io/qr-code-api
• OpenAPI spec — https://theqrcode.io/api/public/qr-codes/openapi.json
• Agent guide — https://theqrcode.io/llms-full.txt
