Discount Stack Calculator MCP Connector for Claude

The Discount Stack Calculator is a specialized pricing engine designed to handle complex retail promotions. It accurately calculates final prices by managing multiple discount layers, including sequential percentage stacking, fixed currency reductions, and threshold-based incentives. The engine also processes BOGO (Buy One Get One) logic and handles regional taxation complexities, such as whether tax should be applied to the pre-discount or post-discount subtotal. Use percentage_stacking to compound rates, fixed_reduction for coupons, threshold_incentive for spend-based rewards, bogo_logic for quantity promotions, and regional_taxation for final tax calculations.
