Payqr

Generates payment QR codes in European formats: SPAYD for Czech and Slovak accounts, EPC/GiroCode for SEPA transfers, plus utility codes for plain text, Wi-Fi credentials, and vCard contacts. Also decodes existing QR images. Part of the cz-agents suite but stands alone with no API dependencies or AI features. Useful when you need Claude to produce scannable payment links for invoices or receipts without leaving the conversation. Works over stdio locally or via the hosted endpoint at payqr.cz-agents.dev. The encode operations take account details and amounts, return base64 or SVG, and handle all the format quirks so you don't have to look up IBAN validators or SPAYD spec sheets.
