MaiMen Saver

MaiMen Saver is an open-source optimization engine that calculates the cheapest combination of McDonald's menu items, coupons, and discounts.

MaiMen Saver is a budget optimization engine designed for McDonald's customers to calculate the lowest possible payment for food orders. It operates by taking a natural language food request, retrieving real-time prices and coupons via McDonald's MCP, and running a combinatorial optimization algorithm to find the best savings. The software targets McDonald's fans and office workers ordering group meals who want to maximize discounts without manual coupon matching. It differentiates itself by using deterministic integer arithmetic rather than LLM guesswork to ensure reproducible results. The project includes an interactive web page, a dual-mode MCP tool integration, and a budget-filling radar.
