Overview
What is Calculator MCP Server?
A comprehensive calculator implemented as a Model Context Protocol (MCP) server using TypeScript. It exposes a wide range of mathematical functions as MCP tools, allowing language models connected via MCP clients (like Claude for Desktop, Cursor, etc.) to perform calculations.
How to use Calculator MCP Server?
Install Node.js (v16+), clone the repository, run npm install and npm run build. Then configure your MCP client (e.g., Claude for Desktop) by editing its claude_desktop_config.json to add the server with the absolute path to build/index.js, and restart the client.
Key features of Calculator MCP Server
- Basic arithmetic (addition, subtraction, multiplication, division)
- Exponents and roots (power, square root)
- Trigonometry (sine, cosine, tangent) in radians
- Inverse trigonometry (arcsine, arccosine, arctangent, arctan2) in radians
- Degree/radian conversion
- Logarithms (natural log, base-10 log, log with arbitrary base)
- Constants (pi, Euler's number)
- Factorial, percentage, modulo, absolute value, rounding (floor, ceiling, round)
Use cases of Calculator MCP Server
- AI assistants performing precise mathematical calculations
- Developers integrating mathematical capabilities into AI-powered applications
- Automating calculations in data analysis or scientific computing workflows
- Supporting educational tools that require step-by-step computation
Frequently asked questions
How do I install Calculator MCP Server?
Clone the repository, run `npm install` to install dependencies, then `npm run build` to compile the TypeScript code.
How do I connect Calculator MCP Server to Claude for Desktop?
Edit Claude's MCP configuration file (located at `~/Library/Application Support/Claude/claude_desktop_config.json` on macOS) and add an entry under `mcpServers` with the command `node` and the absolute path to `build/index.js` as an argument. Restart Claude for Desktop.
What transport protocol does Calculator MCP Server use?
It uses the MCP stdio transport.
What mathematical functions are available?
Functions include basic arithmetic, exponents and roots, trigonometry, inverse trigonometry, degree/radian conversion, logarithms, constants, factorial, percentage, modulo, absolute value, floor, ceiling, and rounding.
