Calculator MCP Server

A simple Model Context Protocol (MCP) server built with FastMCP that provides basic calculator tools.

Remote Access

You can access this MCP server remotely at: https://calculator-mk.fastmcp.app/mcp

Using with Claude Desktop or Other Applications

To use this MCP server with Claude Desktop or any other MCP-compatible application:

1. Configure your MCP client to connect to the remote URL: https://calculator-mk.fastmcp.app/mcp
2. Once connected, you can use calculator functions directly in your conversations:
   • Ask Claude to "add 10 and 5"
   • Request calculations like "multiply 25 by 4"
   • Perform complex math operations through natural language

The server supports the following calculator operations:

• Addition (add)
• Subtraction (subtract)
• Multiplication (multiply)
• Division (divide) - Includes zero division protection

Features

This MCP server exposes the following calculator tools:

• add: Adds two integers
• subtract: Subtracts two integers
• multiply: Multiplies two integers
• divide: Divides two integers (with zero division check)
