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)
