MCP TypeScript Simple Template

A simple TypeScript template for building Model Context Protocol (MCP) servers. This project provides a foundation for creating custom MCP tools that can be integrated with AI systems.

Overview

This template implements a basic MCP server with a sample BMI calculator tool. It demonstrates how to:

Set up an MCP server in TypeScript
Define and implement MCP tools with input validation using Zod
Connect the server to standard I/O for communication

Prerequisites

Node.js (v20 or higher recommended)
npm or yarn

Installation

Clone this repository
Install dependencies:

npm install

Project Structure

index.ts - Main server implementation with sample tool
package.json - Project dependencies and scripts
tsconfig.json - TypeScript configuration

Usage

Building and Running

Build and start the server:

npm start

This will compile the TypeScript code and start the MCP server.

Development

For development, you can:

Modify index.ts to add your own tools
Run the build command to compile:

npm run build

Creating Custom Tools

To create a new tool, follow this pattern in index.ts:

server.tool(
  "your-tool-name",
  {
    // Define input schema using Zod
    paramName: z.string(),
    // Add more parameters as needed
  },
  async ({ paramName }) => ({
    content: [{
      type: "text",
      text: "Your tool's response"
    }]
  })
);

Dependencies

@modelcontextprotocol/sdk - Core MCP SDK
zod - Schema validation
dotenv - Environment variable management
typescript - TypeScript compiler
