Partial The UI and LLM-driven Q&A are buildable, but checking coupon validity store by store depends on McDonald's private backend APIs and account authentication.
What it would actually take: The stack would be a coupon-claiming client plus an MCP server, with per-store validation calls through reverse-engineered McDonald's China app endpoints and price-after-coupon math. The hard parts are authenticated access to undocumented APIs, signature or device-token handling, and terms-of-service and account-risk management, which call for reverse-engineering and mobile-security expertise.
