Math-MCP

A Model Context Protocol (MCP) server that provides basic mathematical, statistical and trigonometric functions to Large Language Models (LLMs). This server enables LLMs to perform accurate numerical calculations through a simple API.

Features

Basic arithmetic operations (addition, subtraction, multiplication, division)
Statistical functions (sum, mean, median, mode, min, max)
Rounding functions (floor, ceiling, round)
Trigonometric functions (sin, cos, tan, and their inverses; degrees/radians conversions)
