Mcp Nupay

Overview

Mcp Nupay is a Model Context Protocol server that connects AI assistants to NuBank's merchant checkout system, enabling Pix payments and one-click wallet transactions for over 100 million Brazilian users. Rather than manually switching between applications, AI agents can call NuPay payment tools directly through the MCP interface.

The server runs locally via the npm package @codespar/mcp-nupay, communicating over stdio. You'll need to provide NUPAY_MERCHANT_KEY and NUPAY_MERCHANT_TOKEN as environment variables for authentication. Version v0.2.2 is available under the MIT license, with the source code hosted at codespar/mcp-dev-latam on GitHub, where it has accumulated 269 stars.

Mcp Nupay is listed in the AI & Agents category on mcp.site and works with MCP clients including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, and Zed. If you maintain this server for codespar, claim this listing to verify ownership and keep information up to date.
