Generate UPI payment links and QR codes for Indian UPI IDs, calculate GST and MSMED late-payment interest, understand UPI payment errors, and compute merchant discount rates. All tools run locally with no data storage.

Example request: "Generate a UPI QR code for my shop so customers can pay me, and calculate the GST on an invoice amount."

How to connect: Not in Muse's Connectors list yet, but Muse can still use it. Paste this into Muse: "Use Pro UPI QR to help me. It is a free service with an MCP server at https://www.proupiqr.in/mcp/. It does not need an API key. Ask me before you share anything with it." Muse asks before it shares anything with the app's site. Meta does not review apps used this way, so only use ones you trust. We tested this in the Muse app on September 24, 2026: Muse used an app's link directly this way and returned a live answer.
