What problem does it solve?
Payment QR specs are easy to get wrong under time pressure, breaking bank-app scans and delaying EU invoicing features.
Who is it for?
Indie developers adding CZ/SK SPAYD or SEPA QR payments to SaaS billing, donations, or internal finance tools via MCP.
Skip if: Merchants who only need US-centric payment links or full PCI card processing without QR string generation.
What do I get? / Deliverables
Your agent outputs valid QR payload strings and decoded content you can paste into invoices, APIs, or test fixtures immediately.
- Spec-aligned SPAYD and EPC/GiroCode payment QR strings
- Wi-Fi, vCard, and text QR payloads for product flows
- Decoded QR content for debugging and support scenarios
Recommended MCP Servers
Journey fit
QR payment strings are implementation artifacts you wire into apps, invoices, and admin tools during the build phase. payqr is an integration-focused MCP for encoding/decoding standards-backed QR content, not market validation or launch distribution.
How it compares
QR payload MCP utility, not a payment gateway or subscription billing platform.
