A straightforward MCP server that gives Claude access to mathematical functions through a Node.js backend. Exposes basic arithmetic (add, subtract, multiply, divide), statistical operations (mean, median, mode, min, max), and trigonometric functions (sin, cos, tan plus their inverses). Handles array operations for multi-number calculations and includes degree/radian conversions. You'd reach for this when you need Claude to perform precise numerical computations instead of approximating math in natural language, especially for statistical analysis or trigonometric calculations where accuracy matters more than rough estimates.
