Math Mcp

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, sum, modulo)
• Statistical functions (mean, median, mode, min, max)
• Rounding functions (floor, ceiling, round)
• Trigonometric functions (sin, cos, tan, and their inverses; degrees/radians conversions)

Installation

> Note: Ensure you have Node.js installed on your computer.

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"]
}

Here is an example for OpenCode

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

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

> Note: This project comes prebuilt, so installation is easy but if you change anything in the code, rebuild the project with npm run build.
