QR Code

Generate and decode QR codes. Two tools, zero configuration.

create_qr encodes any text or URL into a QR code image URL (10px to 1000px). read_qr decodes a QR code from any publicly accessible image URL.

Quick start

Generate a QR code for a URL:

curl -X POST https://gateway.pipeworx.io/qrcode/mcp \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"create_qr","arguments":{"data":"https://example.com","size":300}}}'

The response contains a url field you can embed directly in <img> tags or download.

Decoding

Pass any image URL containing a QR code to read_qr and get the decoded text back. Works with PNGs, JPEGs, and most common image formats.
