# 🌦️ MCP Server - Weather Data Fetcher

This project is a **Model Context Protocol (MCP) server** that provides simple weather data based on city names. It demonstrates how to use **Node.js, MCP SDK, and Zod** to build a server and client that communicate over `stdio`.

---

## 📌 Features

- ✅ MCP Server built using `@modelcontextprotocol/sdk`
- ✅ Provides weather details (temperature + forecast) for cities
- ✅ Example: *Noida → 30°C, chance to rain* | *Delhi → 45°C, high temperature*
- ✅ Validates input with **Zod**
- ✅ Includes **client script** for testing

---

## 🛠️ Tech Stack

- **Node.js** (v18+ recommended)
- **MCP SDK** (`@modelcontextprotocol/sdk`)
- **Zod** for schema validation
- **Tested with STDIO client-server transport**
