Live US Severe Weather Warnings

OperationalCredits 5 per callp50 413msWeather

Overview

Send a latitude and longitude for the alerts covering one place, or a two-letter state code for everything in effect across the state. Every plan gets the event, severity, urgency, area, timing and safety instructions. Paid plans add the full forecaster description and the warning polygon as GeoJSON, ready to draw on a map.

The tool

Once your client is connected to the VerveKit server, this appears in its tool list as WeatherAlertsSkill. It is read-only and open-world — it fetches and never mutates anything on your side — so most clients call it without asking you to confirm.

Tool call
{
  "name": "WeatherAlertsSkill",
  "arguments": {}
}

Connecting

One server URL covers every skill in the catalog, including this one. Authorization is OAuth: the client opens a browser once, and there is no key to paste into a config file.

{
  "mcpServers": {
    "vervekit": {
      "url": "https://api.vervekit.com/v1/mcp"
    }
  }
}

Per-client setup — Claude, Cursor, VS Code, ChatGPT — is on the MCP setup page.

Arguments

These are the properties on the tool's inputSchema, so a well-behaved client validates them before the call is made. Premium arguments are accepted on every plan but only take effect on plans that include them.

ArgumentTypeDescription
latOptionalnumberLatitude of the location to check. Send with lon
range -90–90
lonOptionalnumberLongitude of the location to check. Send with lat
range -180–180
stateOptionalstringTwo-letter US state or territory code (e.g., MO) for every alert in effect across it. Used when lat and lon are not sent

What the model gets back

The result carries a structuredContent object matching the tool's declared outputSchema, so a client reads fields without parsing prose. status is "ok" and error is null on success; a null field means the value was not available for that input, not that the call failed.

Failure modes

Errors come back as tool errors carrying a sentence the model can act on, not a bare status code. Error handling covers the full list.

StatusWhat it means
400 / 422The arguments did not validate. The message names the offending one.
401The OAuth session is invalid or expired — reconnect the server.
403Blocked by a key restriction or an IP allow-list. Never a bad identity.
404This skill is not part of VerveKit. Check the catalog.
429Out of credits, or a brief rate limit. The message tells them apart.

A call costs 5 credits each time the tool actually runs; a model that reasons about the tool without calling it costs nothing.

Use cases

Field Crew Safety
Dispatch and workforce apps check each job site for active tornado, lightning and flood warnings before sending crews out, and pull workers back when a warning is issued for their location.
Event and Venue Operations
Outdoor venues and event organizers watch for severe thunderstorm and high wind warnings at their exact location to trigger shelter plans and delays early.
Logistics and Fleet Routing
Fleet software checks warnings along delivery stops and depots to reroute around winter storms, flooding and dust storms before drivers reach them.
Property and Home Monitoring
Smart home and property management apps notify owners when a freeze, flood or hurricane warning covers a home so they can act before damage happens.
Weather Apps and Widgets
Weather apps draw storm-based warning polygons on their maps and show the most severe alert first, with the forecaster's own instructions.
