🤔 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 configurationchatgpt-config.json- ChatGPT plugin configurationmcp-config.json- Generic MCP server configuration.env- Environment variables and API keyspackage.json- Node.js dependencies and scripts
🏠 Local Development
Development Scripts
We provide PowerShell scripts for easy development:
scripts/setup.ps1- Initial setup and dependency installationscripts/start-dev.ps1- Start development server with hot reloadscripts/test.ps1- Run tests and validation
Environment Setup
- Copy
.env.exampleto.env - Fill in your API keys and configuration
- 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
- Connection Refused: Check if MCP server is running
- Authentication Errors: Verify API keys in
.env - Tool Not Found: Ensure tools are properly registered
- 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
