generate_qr_basicLABSCO SUMMARY
QR codes past the one-liner.
Beyond generating a code it validates what goes in, styles the output and reads codes back, so the one you send to print is one that has been checked.
What it is
A Node server for QR code generation and analysis, extending @jwalsh/mcp-server-qrcode. It makes single codes, styled codes and batches, builds the specialized formats, and decodes and grades codes you already have.
What you get
- generate_qr_basic makes a plain code; generate_qr_styled adds logo embedding, custom colors and rounded corners
- generate_qr_batch makes many at once; list_qr_templates offers pre-defined shapes for common cases
- generate_vcard_qr, generate_wifi_qr and generate_event_qr build contact cards, WiFi credentials and calendar events
- decode_qr_image reads the content back out of a QR image
- analyze_qr_quality grades readability; optimize_qr_content and validate_qr_content check and tighten the content before it is printed
- get_qr_statistics reports generation patterns over time
- PNG, SVG and PDF output
Requirements
Node, cloned and built from the repository: npm install, npm run build, npm start. Output directory, default size and error correction level are set in the client config as QR_OUTPUT_DIR, QR_DEFAULT_SIZE and QR_DEFAULT_ERROR_CORRECTION.
Setup effort
Build from source — git clone https://github.com/myownipgit/mcp-server-qrcode-enhanced.git
USE CASES
01
Making a QR code for a link
One call, one code, with the URL validated before it is encoded.
02
Putting a logo on a code for print
Styling and a readability grade together, because a logo in the middle is exactly what breaks scanning.
03
Handing out WiFi without reading a password aloud
Network name and credentials encoded as a code guests scan, rather than a password written on a card.
04
Putting a contact card on a badge
A vCard code that saves straight into a phone's contacts instead of being typed in.
05
Reading a code you were sent
The content is decoded out of the image, so what a code actually points at is known before anyone scans it.
06
Generating a run of codes at once
A batch from a list, with templates for the shapes you keep making.
