Model Context Protocol (MCP) - Complete Implementation Guide

🚀 Overview

Model Context Protocol (MCP) is an open standard that enables seamless integration between AI applications and external data sources and tools. This guide provides a complete end-to-end implementation with all necessary configuration files and integration examples for ChatGPT, Claude, and other AI models.

🤔 What is MCP?

MCP (Model Context Protocol) is a standardized way to:

  • Connect AI models to external data sources
  • Provide tools and functions that AI models can use
  • Enable secure and controlled access to resources
  • Create reusable components across different AI applications

Key Components:

  • MCP Server: Provides tools, resources, and prompts
  • MCP Client: AI applications that consume MCP services
  • Transport Layer: Communication protocol (stdio, HTTP, WebSocket)

✨ Benefits

  • Standardized Integration: Universal protocol for AI model connections
  • Security: Controlled access to external resources
  • Reusability: One MCP server can serve multiple AI applications
  • Extensibility: Easy to add new tools and resources
  • Local Development: Run everything locally for privacy and control

🔧 Prerequisites

Required Software:

  • Node.js (v18 or later) or Python (3.8+)
  • Git
  • PowerShell (Windows)
  • VS Code (recommended)

For AI Model Integration:

  • API keys for your chosen AI models
  • Claude Desktop, ChatGPT Desktop, or compatible client

🚀 Quick Start

1. Clone and Setup

# Create project directory mkdir mcp-implementation cd mcp-implementation # Initialize the project git init npm init -y # or use Python if preferred

2. Install Dependencies

# For Node.js implementation npm install @modelcontextprotocol/sdk express cors dotenv # For Python implementation (alternative) pip install mcp python-dotenv fastapi uvicorn

3. Run the Example Server

# Start the MCP server node server.js # Or for Python python server.py

4. Configure Your AI Client

Update your AI client configuration (examples provided below for each platform).

🛠️ Server Implementation

Node.js MCP Server

Our MCP server will provide:

  • File system tools
  • Web scraping capabilities
  • System information
  • Custom business logic

See server.js for the complete implementation.

Python MCP Server (Alternative)

For Python developers, we also provide a Python implementation in server.py.

🤖 AI Model Integration

Claude Desktop Integration

Claude Desktop has native MCP support. Configuration is done through claude_desktop_config.json.

ChatGPT Integration

Integration through custom plugins or API wrapper. See chatgpt-integration/ directory.

Other AI Models

Generic HTTP client implementation for any AI model that supports external tool calling.

⚙️ Configuration Files

This repository includes configuration files for:

  • claude_desktop_config.json - Claude Desktop MCP configuration
  • chatgpt-config.json - ChatGPT plugin configuration
  • mcp-config.json - Generic MCP server configuration
  • .env - Environment variables and API keys
  • package.json - Node.js dependencies and scripts

🏠 Local Development

Development Scripts

We provide PowerShell scripts for easy development:

  • scripts/setup.ps1 - Initial setup and dependency installation
  • scripts/start-dev.ps1 - Start development server with hot reload
  • scripts/test.ps1 - Run tests and validation

Environment Setup

  1. Copy .env.example to .env
  2. Fill in your API keys and configuration
  3. Run the setup script
.\scripts\setup.ps1

🚀 Deployment

Local Deployment

# Production build npm run build # Start production server npm start

Docker Deployment

# Build Docker image docker build -t mcp-server . # Run container docker run -p 3000:3000 --env-file .env mcp-server

Cloud Deployment

Instructions for deploying to:

  • Heroku
  • AWS Lambda
  • Google Cloud Functions
  • Azure Functions

🔧 Troubleshooting

Common Issues

  1. Connection Refused: Check if MCP server is running
  2. Authentication Errors: Verify API keys in .env
  3. Tool Not Found: Ensure tools are properly registered
  4. CORS Issues: Check CORS configuration in server

Debugging

# Enable debug logging $env:DEBUG = "mcp:*" node server.js

Health Check

# Test server health curl http://localhost:3000/health
