What is the Percentage Calculation Engine MCP Server?

LLMs frequently fail when applying layered financial math, such as calculating a 15% discount followed by a 20% tax. They guess the answer based on training data. This MCP brings pure, native Javascript logic to percentage math.

The Superpowers

Flawless Financials: Ensure your AI calculates invoice discounts, VAT taxes, and interest correctly every single time.
Absolute Determinism: No stochastics. Just native mathematical evaluation executed at the edge.

Built-in capabilities (2)

calculate_increase_by

Increases or decreases a value by X percent deterministically (use negative percent for discount)

calculate_percent_of

Pass the base value and the percentage to compute. Essential for discount calculations, tax rates, and financial reports. Calculates X percent of a total value deterministically
