🌤️ Weather MCP Agent: Global Intelligence System

Next-Generation Agentic AI powered by the Model Context Protocol (MCP) and Llama 3 (Groq). A real-time, multi-modal weather intelligence system that bridges the gap between Large Language Models and deterministic data tools.

---

🚀 Overview

The Weather MCP Agent is a state-of-the-art implementation of the Model Context Protocol (MCP), designed to demonstrate the future of AI interoperability. Unlike traditional chatbots that hallucinate data, this agent uses a standardized protocol to "connect" to live tools—fetching real-time weather forecasts, alerts, and atmospheric analytics for any city on Earth.

Built on Streamlit for a reactive UI and powered by Groq's LPU for near-instant inference, this system showcases how Agentic AI can orchestrate complex workflows (Geocoding -> Weather API -> Conversational Synthesis) in milliseconds.
