Weather

A straightforward weather lookup that wraps wttr.in with curl, no API key required. You get current conditions, multi-day forecasts, and customizable output formats including JSON and one-line summaries. The format codes (%c for emoji, %t for temp, %w for wind) make it easy to build exactly the response you need. Works globally with city names or airport codes. It's rate limited since it's a free service, so don't hammer it, but for occasional weather checks or travel planning it does the job without the usual API signup dance.

Weather

Use for current weather, rain/temperature checks, forecasts, and travel planning. Need a city, region, airport code, or coordinates.

Preferred: web_fetch

Use web_fetch first when the tool is available. Request JSON because wttr.in returns browser-oriented HTML for many text formats when called with a browser-like User-Agent.

await web_fetch({
  url: "https://wttr.in/London?format=j2",
  extractMode: "text",
  maxChars: 12000,
});

For short answers, summarize current_condition[0], nearest_area[0], and the first entries in weather[]. Use format=j2 for normal summaries because it omits bulky hourly data and fits the default web_fetch output cap. Useful JSON fields:
