The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
get_earthquakes ~201
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.
| Name | Type | Req | Description |
|---|---|---|---|
| hours | integer | – | Time window in hours. Max 168 (7 days). Defaults to 48. |
| include_unreviewed | boolean | – | Include automatic unreviewed detections. Defaults to false. |
| min_magnitude | number | – | Minimum magnitude (Mlw). Defaults to 0 (all events). |
| near | object | – | Custom point + radius filter. Mutually exclusive with 'region'. |
| region | string | – | Named region preset. Mutually exclusive with 'near'. Useful for monitoring specific volcanic systems. |
No output schema declared.
No examples provided.
get_weather_forecast ~167
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'.
| Name | Type | Req | Description |
|---|---|---|---|
| hours | integer | – | How many hours of forecast to return, starting from now. Defaults to 72 (3 days). Max 240 (10 days). Keep this tight when the user asks about a specific near-term time. |
| lang | string | – | Language for the text-forecast fallback. Defaults to 'en'. |
| stations | array | – | Station IDs or names. Defaults to ['Reykjavík']. |
No output schema declared.
No examples provided.
get_weather_now ~129
Get current weather observations for locations in Iceland. Returns temperature (°C), 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 — call list_weather_stations to discover available stations.
| Name | Type | Req | Description |
|---|---|---|---|
| lang | string | – | Language for description fields. Defaults to 'en'. |
| stations | array | – | Station IDs or names, e.g. ['1470', 'Akureyri']. Diacritics optional. Defaults to ['Reykjavík'] when omitted. |
No output schema declared.
No examples provided.
get_weather_text ~94
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.
| Name | Type | Req | Description |
|---|---|---|---|
| category | string | – | Which text forecast to fetch. Defaults to 'national'. |
| lang | string | – | Language. Icelandic versions are often more detailed. Defaults to 'en'. |
No output schema declared.
No examples provided.
get_weather_warnings ~100
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'.
| Name | Type | Req | Description |
|---|---|---|---|
| include_expired | boolean | – | Include expired alerts (default false). |
| lang | string | – | Filter to info blocks in this language. Default returns all. |
No output schema declared.
No examples provided.
list_weather_stations ~121
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).
| Name | Type | Req | Description |
|---|---|---|---|
| limit | integer | – | Maximum number of stations to return. Defaults to all. |
| region | string | – | Case-insensitive substring match against the station's region label (e.g. 'north', 'capital', 'westfjords'). Optional. |
