OpenQR tools (20, 10 write)

write = sends, deletes, buys or posts

bulk_create_dynamic_qrwrite actionFree
Create up to 200 dynamic QR codes at once. Requires an OpenQR API key.
clear_subdomainFree
Release the branded subdomain. Codes stay live on the plain short link; only the {name}.oqr.to form stops resolving. The name becomes claimable by someone else. Requires an OpenQR API key.
create_dynamic_qrwrite actionFree
Create an editable (dynamic) QR code whose destination you can change later without reprinting. Requires an OpenQR API key.
create_folderwrite actionFree
Create a folder to organise codes. Requires an OpenQR API key.
create_link_aliaswrite actionFree
Create an extra short link (link alias) that resolves where one of your dynamic codes points: share a different slug per channel while the QR keeps its own slug, so QR scans and link clicks are counted separately. Free accounts have no alias allowance; Pro includes 10. Requires an OpenQR API key.
create_static_qrwrite actionFree
Save a static QR code to your library from structured fields: wifi, contact (vCard), email, SMS, WhatsApp, location, text, phone or URL. Static codes bake the content into the code itself — no short link, no scan analytics, not editable later. Render the returned payload with generate_qr. Requires an OpenQR API key.
create_themewrite actionFree
Save a reusable style theme. `style` is a QR style object (fgColor, bgColor, dotType, cornerSquareType, etc.). Requires an OpenQR API key.
delete_dynamic_qrwrite actionFree
Permanently delete a dynamic QR code. The short link stops working. Requires an OpenQR API key.
delete_folderwrite actionFree
Delete a folder (its codes are un-filed, not deleted). Requires an OpenQR API key.
delete_themewrite actionFree
Delete a saved theme. Codes already styled with it keep their look. Requires an OpenQR API key.
generate_qrFree
Generate a static QR code from any text/URL. Returns a PNG image (or SVG markup). Requires an OpenQR API key.
get_dynamic_qrFree
Get the full details of one of your QR codes by id: destination, short link, label, type, tags, folder, status and created date. Requires an OpenQR API key.
get_scansFree
Get scan statistics for a dynamic QR code. Requires an OpenQR API key.
get_subdomainFree
Show the branded subdomain on this account ({name}.oqr.to). Reports whether it is currently suspended — a suspended subdomain redirects to the plain short link instead of serving, which happens when a Pro plan lapses. Requires an OpenQR API key.
list_dynamic_qrFree
List your dynamic (editable) QR codes — id, short URL, destination, label and status. Requires an OpenQR API key.
list_foldersFree
List your folders (id and name). Requires an OpenQR API key.
list_link_aliasesFree
List the link aliases of one dynamic code. Requires an OpenQR API key.
list_themesFree
List your saved style themes (id, name) — apply one by passing its id or name as `theme` to generate/create/update tools. Requires an OpenQR API key.
set_subdomainFree
Claim or change the branded subdomain so codes also resolve at {name}.oqr.to. Pro only. Codes keep working on the plain short link either way, so changing this never breaks anything already printed. Requires an OpenQR API key.
update_dynamic_qrwrite actionFree
Edit a dynamic QR code: change its destination, label, custom short link (slug), tags or folder. Pass only the fields you want to change. Requires an OpenQR API key.

What the publisher says

From the OpenQR repository's README, as published. We do not edit it. Read it on GitHub

OpenQR

Free, open-source, watermark-free QR code generator. Runs entirely in your browser — no tracking, no sign-up, no limits.

Most online QR generators bait you with "free" and then add a watermark, cap your download size, hide vector export behind a paywall, or route your code through their servers so it dies when you stop paying. A QR code is just an open standard (ISO/IEC 18004) that costs nothing to generate. OpenQR keeps it that way.

This repository is the basic generator tool — the reference open-source implementation. It is deliberately small and easy to fork.

If OpenQR is useful to you, a star on the repository helps other people find it. That is the whole ask.

Hosted version: free API, MCP server and editable codes

Everything in this repo is and stays free, with no watermark and no expiry. The hosted build at openqr.uk adds an optional account layer for people who want editable codes and automation:

you've printed it. 1 free on a free account (7 days of scans by country); 25 editable codes on Pro at £9/month or £90/year, which also unlocks a 90-day scan-analytics window plus town and region detail, device and referrer breakdowns with CSV export, a branded subdomain, and password-protected codes. Existing subscribers keep their current plan and price.

Dynamic / editable QR codes with scan analytics. Change the destination after

OpenAPI spec at /openapi.json; interactive docs at openqr.uk/api.

Free REST API. Generate codes and manage dynamic codes programmatically.

Generate and manage QR codes directly from Claude, Cursor or any MCP client. Listed in the official MCP Registry. Remote-capable clients connect to that URL directly; stdio-only clients can bridge to it with npx -y @open-qr/mcp and OPENQRAPIKEY set (details).

Hosted MCP server at https://openqr.uk/mcp (Streamable HTTP).

The static generator in this repository never calls any of that. It stays 100% client-side (see Privacy), and none of it is required to use or self-host the generator.

Connecting an MCP client

Get a free key at openqr.uk/api, then point your client at the server with the key as an auth header.

Claude Code:

claude mcp add --transport http openqr https://openqr.uk/mcp \
  --header "Authorization: Bearer oqr_YOUR_KEY"

Cursor (~/.cursor/mcp.json), and any other client that speaks Streamable HTTP:

{
  "mcpServers": {
    "openqr": {
      "url": "https://openqr.uk/mcp",
      "headers": {
        "Authorization": "Bearer oqr_YOUR_KEY"
      }
    }
  }
}

Tools

The hosted MCP server at https://openqr.uk/mcp exposes these tools (run tools/list for the live set). Every tool requires a free API key — create one at openqr.uk/api and pass it as Authorization: Bearer oqr_... on the MCP connection.
