📦 Installation

Option 1: Use with npx (Recommended - No Installation Required)

npx mcp-server-starter init --name my-server

This runs the latest version without installing anything globally.

Option 2: Install Globally

npm install -g mcp-server-starter

Then use it anywhere:

mcp-server-starter init --name my-server
mcp-server-starter add-tool --name myTool

Option 3: Install as Project Dependency

npm install mcp-server-starter --save-dev

Use in package.json scripts:

{
  "scripts": {
    "create-server": "mcp-server-starter init",
    "add-tool": "mcp-server-starter add-tool"
  }
}

🎬 Quick Start

Create a new MCP server

npx mcp-server-starter init --name my-awesome-server
cd my-awesome-server
npm install
npm run build
npm start

That's it! You now have a working MCP server with a sample echo tool.

📚 Usage

Initialize a new server

# Interactive mode
npx mcp-server-starter init

# With options
npx mcp-server-starter init --name my-server --preset minimal

# With description
npx mcp-server-starter init --name my-server --description "My custom MCP server"

Add tools to your server

# Navigate to your server directory
cd my-server

# Add a new tool (interactive)
npx mcp-server-starter add-tool

# Add with options
npx mcp-server-starter add-tool --name calculator --title "Calculator" --description "Performs calculations"

# Force overwrite existing tool
npx mcp-server-starter add-tool --name calculator --force

🔌 Connect to Claude Desktop

Add to your claude_desktop_config.json:

{
  "mcpServers": {
    "my-server": {
      "command": "node",
      "args": ["/absolute/path/to/my-server/dist/server.js"]
    }
  }
}

Restart Claude Desktop, and your tools will be available!

🛠️ Tool Development

Example: Calculator Tool

// src/mcp/tools/calculator.ts
import { z } from 'zod';
import type { Tool } from './index.js';

const calculatorInputSchema = z.object({
  operation: z.enum(['add', 'subtract', 'multiply', 'divide']),
  a: z.number(),
  b: z.number(),
});

export const calculatorTool: Tool = {
  name: 'calculator',
  description: 'Performs basic math operations',
  inputSchema: {
    type: 'object',
    properties: {
      operation: {
        type: 'string',
        enum: ['add', 'subtract', 'multiply', 'divide'],
      },
      a: { type: 'number' },
      b: { type: 'number' },
    },
    required: ['operation', 'a', 'b'],
  },
  handler: async (args: unknown) => {
    const input = calculatorInputSchema.parse(args);

    let result: number;
    switch (input.operation) {
      case 'add':
        result = input.a + input.b;
        break;
      case 'subtract':
        result = input.a - input.b;
        break;
      case 'multiply':
        result = input.a * input.b;
        break;
      case 'divide':
        result = input.a / input.b;
        break;
    }

    return {
      content: [
        {
          type: 'text',
          text: `Result: ${result}`,
        },
      ],
    };
  },
};

Add it to your server:

npx mcp-server-starter add-tool --name calculator
# Edit src/mcp/tools/calculator.ts with the code above
npm run build
npm start

The tool is automatically registered - no manual imports needed!
