My MCP Server

This project implements a Model Context Protocol (MCP) server using Node.js and TypeScript.

Features

• MCP server with basic tool capabilities
• Implements a calculate tool for basic mathematical operations: add, subtract, multiply, divide
• Handles requests via standard input/output (stdio)

Usage

1. Install dependencies:

   npm install
   

2. Build the project:

   npm run build
   

3. Start the server:

   npm start
   

Tool: calculate

Description: Perform basic mathematical calculations Parameters:

• operation: string (add, subtract, multiply, divide)
• a: number
• b: number

Example Prompt

Calculate 15 + 27 using the calculate tool.

Example Request:

{
  "name": "calculate",
  "arguments": {
    "operation": "add",
    "a": 15,
    "b": 27
  }
}

Example Response:

{
  "content": [
    {
      "type": "text",
      "text": "The result of 15 add 27 is 42."
    }
  ]
}

How to Check This MCP Server in VS Code

1. Open the project folder in VS Code.
2. Open a new terminal in VS Code (`Ctrl+`` or from the menu).
3. Make sure dependencies are installed and the server is running:

   npm install
   npm run build
   npm start
   

4. You can test the MCP server by sending a request using the terminal. For example:

   echo '{"name": "calculate", "arguments": {"operation": "add", "a": 15, "b": 27}}' | npx ts-node src/server.ts
   

5. You should see a response similar to:

   {
     "content": [
       {
         "type": "text",
         "text": "The result of 15 add 27 is 42."
       }
     ]
   }
   

6. For more advanced testing, use an MCP client extension or integrate with other MCP-compatible tools in VS Code.
