What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

Connection: Runs in the cloud
Transport: Streamable HTTP
Category: Marketing & social media
You need to fill in: Authorization

Install

Pick the AI app you use, then copy the settings.

Before you install

Basic checks: 1 of 1 passed
Runs on the maker’s server: what you ask it goes through their server.

Which app do you use?

ClaudeClaude CodeCursorVS CodeChatGPT

Pick your app above. We remember it, so next time the button says “Install in …”.

This address needs a key in a request header, which the add-connector menu cannot set. Use Claude Code, Cursor or VS Code instead.

Run this in your terminal

claude mcp add --transport http qr-code-generator https://mcp.theqrcode.io/mcp --header 'Authorization: your-value'

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

      "headers": {
        "Authorization": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Common questions

Is TheQRCode.io safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: Authorization

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.5.2) reached the registry 24 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

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	all five free, no 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`
`dotStyle`	`square` \	`dots` \	`rounded` \	`extra-rounded` \	`classy` \	`classy-rounded`	no	module shape
`cornerStyle`	`square` \	`dot` \	`extra-rounded`	no	the three corner squares
`frameStyle`	`square` \	`rounded` \	`circle` \	`dashed`	no	`square` means no frame
`caption`	string ≤60	no	text under the code; implies a frame
`format`	`png` \	`svg` \	`pdf`	no	default `png`; svg/pdf need a key

Returns a hosted image URL plus a base64 data URL for inline display. svg and pdf come back as a data URL in the text response rather than an image block, since a PDF is not one and many clients will not draw an SVG one.

Every design option is free, on every plan and with no key at all — colour, size, dot and corner styling, frames and captions, with no watermark on any output. What the paid plans sell is dynamic codes, analytics, stored-code volume and the managed API. Logo embedding is free too but is not a parameter here: it needs a base64 data URL, which is a poor fit for a tool call.

format: "svg" | "pdf" is the one asymmetry, and it is a cost control rather than a paywall: vector and PDF are the most expensive render path, so they are metered per key instead of per IP. Both are free in the dashboard and in the no-signup generator on theqrcode.io, on every plan.

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 format: "svg" | "pdf" 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.

Plans

	Anonymous	Developer ($19/mo)	Pro ($29/mo)
`generate_qr_code`	✅ all 5 types, full design	✅ + svg/pdf output	✅ + svg/pdf output
Codes saved to account	❌ 24h preview link	✅ permanent	✅ permanent
`list_qr_codes`	❌	✅	❌
`get_analytics`	❌	✅	❌
MCP rate limit	100/hr per IP	2,000/hr per key	500/hr per key

MCP calls also count toward the key's 5,000/hr REST API limit; the MCP limit is a cap within it.

API keys: https://theqrcode.io/pricing

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 run start:http # HTTP server on $PORT (or: npm run dev) npm start # one session over stdio, for a local client npm test

Over stdio, set THEQRCODE_API_KEY to unlock the account tools; without it you get the keyless set.

Env	Default	Purpose
`QR_API_BASE`	`https://theqrcode.io`	REST API this server wraps
`PORT`	`3001`	listen port (HTTP mode)
`THEQRCODE_API_KEY`	—	API key for stdio mode (HTTP takes it per request as a Bearer token)

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, text and email, with scan analytics by time, device and approximate location. Static codes never expire, printed codes are never switched off to force an upgrade, and the design of a code is never billed for.

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