Brazil Payments MCP — let AI agents accept Pix & card payments in Brazil
Live · MCP endpoint:
https://mcp-br.wishpool.app/mcp· Listed on the official MCP Registry asapp.wishpool/brazil-payments-mcp· Sister servers: Taiwan · Japan · Korea · Indonesia · India
A remote MCP server that lets any AI agent (Claude, ChatGPT, Cursor…) accept payments in Brazil:
- ⚡ Pix — Brazil's national instant payment rail, the way Brazil actually pays
- 💳 Credit & debit cards / boleto
- 🔍 Payment status check — pull-based, no webhook needed; no confirm step, payment completes automatically
v0.1 routes through Mercado Pago Checkout Pro, the largest payment platform in Latin America. The provider registry is built for aggregation — more Brazilian gateways join behind the same tools.
⚖️ Stateless translation layer: funds always flow buyer → Mercado Pago → merchant directly. This server never holds, moves, or stores funds or credentials — no database at all.
