🛡️ What is MCP?

The Model Context Protocol is a standardized way for AI applications to interact with external tools and data sources. This server enables:

🤖 AI Integration: Direct integration with Claude, ChatGPT, and other AI models

🔧 Tool Execution: AI can perform calculations and data operations

📊 Data Access: AI can query and analyze your data

🔄 Context Preservation: Maintain state across AI interactions

🌟 Features

🛠️ Tools (Executable Functions)

Calculator Tool: Perform mathematical operations (add, subtract, multiply, divide)
Data Retrieval Tool: Get specific records by ID and type
Data Creation Tool: Create new users, products, and orders
Advanced Validation: Input validation for all tool operations

📁 Resources (Data Access)

Users Resource: Access user data collection
Products Resource: Access product catalog
Orders Resource: Access order history
Settings Resource: Server configuration and system settings

💾 Data Management

  In-Memory Data Store: Fast, efficient data storage using Maps
  CRUD Operations: Complete Create, Read, Update, Delete functionality
  Search Capabilities: Query data across all collections
  Statistics Generation: Real-time data analytics and metrics

🏗️ Architecture

MCP Server Components:

🏭 Factory Pattern → Server Creation & Configuration
🔧 Tools Handler → Executable Functions (calculate, get_data, create_data)
📂 Resources Handler → Data Access (users, products, orders, settings)
💾 Data Service → CRUD Operations & In-Memory Storage
✅ Validation Utilities → Input Validation & Error Handling
🧪 Test Suite → Comprehensive Testing Coverage

🚀 Quick Start Prerequisites Node.js 16+ npm or yarn
