Common questions

Is Vedurstofa MCP safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.0) reached the registry 7 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

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:

Tool	What it returns
`get_weather_now`	Current AWS observations per station (temperature, wind, pressure, humidity, precipitation).
`get_weather_forecast`	Per-station multi-day forecasts scraped from vedur.is. Falls back to the text forecast if scraping fails.
`get_weather_text`	Prose weather forecasts and text warnings (national, multi-day, or warnings), in English or Icelandic.
`get_weather_warnings`	Structured CAP v1 severe-weather alerts.
`get_earthquakes`	Recent earthquakes with region presets (Reykjanes, Katla, Bárðarbunga, Tjörnes, Askja, Hekla, Grímsvötn) and arbitrary lat/lon radius filters.
`list_weather_stations`	Station catalog for ID/name lookups.

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

User asks about…	Use
Current temperature, wind, pressure at a location	`get_weather_now`
Hourly forecast for the next hours/days at a location	`get_weather_forecast` (pass `hours` to narrow the window)
Narrative / prose forecast (national outlook, multi-day, text warnings)	`get_weather_text`
Severe-weather alerts, storm warnings, structured hazard data	`get_weather_warnings`
Recent earthquakes — volcanic regions, lat/lon radius, magnitude	`get_earthquakes`
"Which stations are there?" / resolving a place name to a station ID	`list_weather_stations`

Multi-tool workflows

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

Degraded responses

get_weather_forecast 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

~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows):

"mcpServers": { "vedurstofa": { "command": "npx", "args": ["vedurstofa-mcp"] } } }

Claude Code

claude mcp add vedurstofa -- npx vedurstofa-mcp

Cursor

~/.cursor/mcp.json:

"mcpServers": { "vedurstofa": { "command": "npx", "args": ["vedurstofa-mcp"] } } }

Cline (VS Code)

In VS Code, open the Cline extension → MCP servers → Edit MCP settings, and add:

"mcpServers": { "vedurstofa": { "command": "npx", "args": ["vedurstofa-mcp"] } } }

ChatGPT

ChatGPT's MCP support (Developer Mode, Plus/Pro and higher) currently accepts only remote MCP servers exposed over an SSE URL, not local stdio servers like this one. To use vedurstofa-mcp with ChatGPT you'd need to wrap it behind an stdio→SSE bridge (e.g. mcp-proxy, supergateway) and point ChatGPT at the bridge URL. See OpenAI's MCP docs for setup.

Example output

get_weather_now with stations: ["Reykjavík"]:

"attribution": "Icelandic Met Office (vedur.is), CC BY-SA 4.0. ...", "source": "https://api.vedur.is/weather/observations/aws/hour/latest", "fetched_at": "2026-04-15T21:00:00.000Z", "data": { "observations": [ { "station_id": "1470", "station_name": "Reykjavík", "observed_at": "2026-04-15T20:50:00.000Z", "temperature_c": 4.2, "wind_speed_ms": 7.1, "wind_direction_deg": 230, "wind_direction_cardinal": "SW", "pressure_hpa": 1008.4, "humidity_pct": 82, "precipitation_mm": 0.0 } ] } }

get_earthquakes with region: "reykjanes" returns a sorted list of events with timestamp, latitude, longitude, depth_km, magnitude, magnitude_type, location, reviewed. Fields default to null when upstream omits them.

Example prompts

"What's the weather in Reykjavík right now?"
"Compare current conditions in Akureyri, Ísafjörður and Höfn."
"Any weather warnings active for Iceland?"
"Earthquakes near Grindavík in the last 24 hours above magnitude 2."
"Show me the Icelandic multi-day text forecast."

Data attribution

Data comes from the Icelandic Meteorological Office under CC BY-SA 4.0. Every response includes an attribution field. The MIT license in this repo covers the server code only, not the data.

Limitations

Forecast scraping is fragile. Per-station forecasts are extracted from inline JavaScript on vedur.is pages. When the HTML changes, the scraper falls back to the national text forecast and marks the response degraded: true. File an issue when you see it.
Forecast station coverage is limited to ~13 major named stations. Others share a regional page or have no scrapeable forecast.
Units are metric: °C, m/s, hPa, mm, km. Claude converts on request.
Timestamps are ISO 8601 UTC. Iceland is on UTC year-round (no DST).

Development

VEDURSTOFA_DEBUG=1 enables debug-level logs on stderr. Stdout is reserved for the MCP protocol.
