      "command": "npx",

A weather MCP server that exposes real-time weather, 3-day forecasts, and current date/time queries through the wttr.in API. It is designed to be consumed by MCP clients to fetch weather information for various locations and to obtain the current date and time in a chosen timezone.

How to use

You can query weather data and current date/time using an MCP client that speaks the Model Context Protocol. Use the provided tools to request weather information for a city, postal code, or geographic coordinates, and to retrieve the current date and time in a specific timezone.

Available tools include get_weather_wttr for weather data and get_datetime for the current date and time. Each tool returns information in a structured format suitable for display in your app or workflow.

How to install

Prerequisites: install Node.js and npm on your development machine.

Install dependencies for the MCP server.

# Install dependencies
npm install

# Build the MCP server
npm run build

Additional configuration and usage notes

Two MCP configurations are shown for running the server. The first uses npx to run the published MCP package directly. The second demonstrates running the built local version from dist/index.js.
