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)
