🚀 Getting Started with Installation

Setup Instructions

To get started, follow these steps:

1. Create Environment Variables: Create a .env file and specify your OpenWeatherMap API key.

   OPENWEATHER_API_KEY=your_api_key_here
   

2. Build the Docker Image:

   docker build -t weather-mcp .
   

3. Run the Application:

   docker run -p 8000:8000 weather-mcp-server
   

4. Access Weather Data: Use a browser or API client to access the live weather data.

   http://localhost:8000/weather?city=Tokyo
   

💡 Key Use Cases in AI Workflows

1. Personalized Notifications and Alerts: Implement custom notifications for users based on real-time weather conditions (e.g., extreme temperature alerts, storm warnings).

2. Enhanced Smart Home Devices: Integrate the Weather MCP Server with smart home devices to provide context-aware functionalities (e.g., adjusting HVAC settings based on external temperature).
