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

Frequently asked questions
Can it calculate discounts?
Yes, by passing a negative percentage.
Is it deterministic?
Absolutely. Pure math evaluation local.
Does it support tax addition?
Yes, simply use the increase_by function.
How does Cline connect to MCP servers?
Cline reads MCP server configurations from its settings panel in VS Code. Add the server URL and Cline discovers all available tools on initialization.
Can Cline run MCP tools without approval?
By default, Cline asks for confirmation before executing tool calls. You can configure auto-approval rules for trusted servers in the settings.
Does Cline support multiple MCP servers at once?
Yes. Configure as many servers as needed. Cline can use tools from different servers within the same autonomous task execution.
