Overview

AI-generated overview

Local MCP server that gives an assistant US National Weather Service alerts by state and short-term point forecasts by coordinates.

What you can do
  • Fetch active NWS weather alerts for a US state by two-letter state code
  • Fetch a short-term point forecast for the next five periods from latitude and longitude
When to use it
Useful when you want an assistant to check current US weather alerts or a brief forecast for a location, for example while planning travel or outdoor work inside the United States.
Requirements
Runs locally as a Python process over stdio; the README installs it with pip and launches it with python -m weather.weather. Needs network access to the public NWS API. No accounts, API keys, environment variables or headers are declared.
Before you install
Coverage is limited to US National Weather Service data, so non-US locations are not supported. The README asks users to respect the public API's usage guidelines and rate limits. No write actions or credentials are involved.

Installation

In SourceWeft

  1. Open Weather Alerts & Forecast in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.
