Show HN: Minimal MCP server in Go showcasing project architecture

A lightweight Model Context Protocol (MCP) server that enables AI assistants like Claude to retrieve and interpret real-time weather data. Installing on Claude Desktop To use your MCP server with Claude Desktop, add it to your Claude configuration: { "mcpServers" : { "weather-mcp-server" : { "command" : " /path/to/weather-mcp-server " , "args" : [], "env" : { "WEATHER_API_KEY" : " your-api-key " } } } } You can get your API key in your personal account at weatherapi.
