🧮 Math & Calculator MCP Server

A powerful Model Context Protocol (MCP) Server that provides advanced mathematical utilities and calculator tools for AI assistants like Claude and other MCP-compatible clients.

📖 About

This MCP server exposes mathematical tools that AI assistants can use to perform calculations, statistical analysis, unit conversions, and more. Built with the Model Context Protocol SDK, it seamlessly integrates with Claude Desktop, VSCode, and other MCP clients.

⚙️ Configuration

For Claude Desktop

Add to your Claude Desktop config file (claude_desktop_config.json):

Windows: %APPDATA%\Claude\claude_desktop_config.json
macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
Linux: ~/.config/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "math-calculator": {
      "command": "node",
      "args": [
        "C:\\path\\to\\Math-Calculator-MCP-Server-\\dist\\index.js"
      ]
    }
  }
}

For VSCode with Cline Extension

Add to VSCode settings (.vscode/settings.json or User Settings):

{
  "mcp.servers": {
    "math-calculator": {
      "command": "node",
      "args": [
        "C:\\path\\to\\Math-Calculator-MCP-Server-\\dist\\index.js"
      ]
    }
  }
}

📚 Usage Examples

Once configured, your AI assistant can use these tools automatically. Here are some example requests:

Basic Calculations

"Calculate 25 * 4"
"What is the square root of 144?"
"Divide 100 by 7"

Statistics

"Calculate the mean of [10, 20, 30, 40, 50]"
"Find median and mode for these numbers: [5, 3, 5, 2, 8, 5]"
"Give me all statistics for [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]"

Unit Conversions

"Convert 100 kilometers to miles"
"How many pounds is 75 kilograms?"
"Convert 32 Fahrenheit to Celsius"

Solve Equations

"Solve x² - 5x + 6 = 0"
"Find solutions for 2x² + 3x - 2 = 0"

Percentages

"What is 15% of 200?"
"Increase 50 by 20%"
"What percentage is 25 of 200?"

Trigonometry

"Calculate sin(30°)"
"What is cos(45°)?"
"Find tan(60°)"
