What is the Weather MCP Server?
This is a local server that provides weather data using the Model Context Protocol (MCP). It currently uses hardcoded weather data but can be easily extended to connect with external weather APIs.How to use the Weather MCP Server?
The server currently runs offline using STDIOserver transport. You can interact with it locally to get weather information. For online access, you would need to implement SSE with an Express server.Use Cases
Ideal for local development, testing MCP implementations, or as a starting point for building more complex weather data services.Key Features
Local MCP ServerImplements the Model Context Protocol for structured data communication
Weather Data ContextUnderstands and responds to weather-related queries with hardcoded data
STDIO Server TransportOperates offline using standard input/output communication
Extensible ArchitectureDesigned for easy integration with external APIs and online deployment
Pros and Cons
Advantages
Simple to set up and run locally
No external dependencies required for basic operation
Clean codebase that's easy to understand and modify
Provides a working example of MCP implementation
Limitations
Currently only works offline
Uses hardcoded weather data instead of real-time information
Limited to weather context (though extensible to other domains)
Requires additional setup for online access
