Vedurstofa tools (6)

write = sends, deletes, buys or posts

Read from the package source without running it. The installed server may list more.

  • get_earthquakes

    Get recent earthquakes in Iceland with magnitude, location, depth, and timestamp. Filter by named region preset (reykjanes, mydalsjokull, bardarbunga, tjornes, katla, askja, hekla, grimsvotn) or a custom lat/lon radius. Defaults to the last 48 hours and excludes automatic (unreviewed) detections.

  • get_weather_forecast

    Get multi-day hourly weather forecasts for locations in Iceland. Returns hour-by-hour predictions for temperature, wind, precipitation, cloud cover, and dew point. Forecasts are regional (covering one of 10 IMO forecast regions) and scraped from vedur.is; if scraping fails the response falls back to the national text forecast and is marked 'degraded'.

  • get_weather_now

    Get current weather observations for locations in Iceland. Returns temperature (\xB0C), wind speed and direction (m/s, cardinal + degrees), pressure (hPa), humidity (%), precipitation (mm/h), and snow/visibility data when available. Accepts station IDs or names \u2014 call list_weather_stations to discover available stations.

  • get_weather_text

    Get written (prose) weather forecasts for Iceland from the Icelandic Meteorological Office. Use for narrative forecasts and text weather warnings. For structured per-station observations use get_weather_now. For structured warnings use get_weather_warnings.

  • get_weather_warnings

    Get active severe-weather warnings (CAP alerts) for Iceland from the Icelandic Meteorological Office. Returns structured alert metadata including severity, certainty, urgency, effective/expiry times, affected areas, and multilingual headlines + descriptions. For narrative text warnings use get_weather_text with category='warnings'.

  • list_weather_stations

    List weather stations in Iceland with their IDs, names, types, and coordinates. Use this to look up station IDs for get_weather_now and get_weather_forecast, or to help users discover stations near a region. Stations are loaded from the Icelandic Meteorological Office (api.vedur.is).

What the publisher says

From the Vedurstofa repository's README, as published. We do not edit it. Read it on GitHub

vedurstofa-mcp

MCP server for Icelandic weather, forecasts, warnings, and earthquakes. Data comes from the Icelandic Meteorological Office (Veðurstofa Íslands, vedur.is). Works with Claude Desktop, Claude Code, and any other MCP client.

What it does

Six tools:

Station inputs accept IDs ("1470") or names with or without diacritics ("Reykjavík", "reykjavik"). Unknown names return a typo-tolerant "did you mean..." error.

For agents

Read this section if you're an AI agent picking tools from this server.

  • No auth, no API key, no setup. Just run npx vedurstofa-mcp over stdio.
  • All data is Icelandic. If the user asks about weather outside Iceland, stop — this server can't help.
  • Every response is a JSON envelope with attribution, source, fetched_at, data, and optionally errors, degraded, truncated. Always cite the attribution field when surfacing data to users.
  • Units are metric. °C, m/s, hPa, mm, km. Convert only when the user asks.
  • Timestamps are ISO 8601 UTC. Iceland is on UTC year-round (no DST).

Tool selection guide

Multi-tool workflows

  • "What's the weather like in Iceland today?" → getweathernow for the user's city + getweatherwarnings to surface any active alerts. Add getweathertext with category: "national" only if the user wants a narrative.
  • "Should I drive from Reykjavík to Akureyri tomorrow?" → getweatherforecast for both endpoints + getweatherwarnings. Don't pull getweathernow unless the user asks about right now.
  • "Are there any earthquakes near me?" → getearthquakes with region preset if the user names a volcanic system (Reykjanes, Katla, etc.), otherwise near: { lat, lon, radiuskm }.

Degraded responses

getweatherforecast scrapes HTML and can fail when the upstream site changes. When this happens, the response carries degraded: true and degraded_reason, and falls back to the national text forecast. Surface this to the user rather than pretending the structured forecast is available.

Install & run

Node 18+ required.

# Latest
npx -y vedurstofa-mcp

# Version-pinned (recommended for configs that shouldn't drift)
npx -y vedurstofa-mcp@1.0.0

The server speaks MCP over stdio, so you won't see interactive output. Plug it into a client.

Claude Desktop

  "mcpServers": {
