Exposes five calculation tools via MCP: a safe expression evaluator supporting functions like sqrt, sin, and log with constants and variables; a unit converter covering length, weight, temperature, data, time, and speed; a statistics calculator for mean, median, variance, standard deviation, and correlation; a number formatter for currency, percentage, scientific notation, and different bases; and a percentage calculator for tips, discounts, and markup. Runs as a Node.js stdio server. Reach for this when you need Claude to handle numerical operations beyond simple arithmetic, whether converting 100 km/h to mph, calculating summary statistics on a dataset, or formatting financial figures with proper separators and currency symbols.
