  • Tools: add, subtract, multiply, divide
  • Easily connectable to Claude Desktop, VS Code, and other MCP clients

Quickstart

Prerequisites

  • Node.js 18+ and npm

Setup

npm install
npm run build

Run the server (for MCP clients)

node build/index.js

MCP Integration

To connect this server to an MCP client (e.g., Claude Desktop, VS Code):

  1. Add an entry to your mcp.json or client config: 
    {
  "servers": {
    "calculator": {
      "type": "stdio",
      "command": "node",
      "args": ["/ABSOLUTE/PATH/TO/build/index.js"]
    }
  }
}
  2. Restart your MCP client and enable the "calculator" server.
