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)

Installation

Installing via Smithery

To install Math-MCP for Claude Desktop automatically via Smithery:

Installing Manually

Just clone this repository and save it locally somewhere on your computer.

Then add this server to your MCP configuration file:

"math": {
  "command": "node",
  "args": ["PATH\\TO\\PROJECT\\math-mcp\\build\\index.js"]
}

Replace PATH\\TO\\PROJECT with the actual path to where you cloned the repository.
