Distance Calculator Skill

Calculate distance between locations

OperationalCredits 2 per callp50 931msGeography

Overview

Distance Calculator works by calculating the distance between two locations based on their latitude and longitude coordinates. It uses advanced algorithms to calculate the distance accurately and returns the distance in miles and kilometers.

The tool

Once your client is connected to the VerveKit server, this appears in its tool list as DistanceCalculatorSkill. 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": "DistanceCalculatorSkill",
  "arguments": {
    "lat1": "36.7783",
    "lon1": "-119.4179",
    "lat2": "34.0522",
    "lon2": "-118.2437"
  }
}

You do not name the tool yourself; the model picks it. Asking about 36.7783 in the terms this skill covers is enough for it to reach for DistanceCalculatorSkill on its own — naming it explicitly also works, and is the way to force the call.

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
lat1RequirednumberThe latitude of the first location
range -90–90
lon1RequirednumberThe longitude of the first location
range -180–180
lat2RequirednumberThe latitude of the second location
range -90–90
lon2RequirednumberThe longitude of the second location
range -180–180

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.

Response fields

Paths are relative to data. Premium fields are absent rather than zeroed on plans that do not include them, so check for presence instead of comparing to 0.

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

Use cases

Delivery Radius Verification
Local couriers check mile distances between warehouse coordinates and customer dropoff points to confirm addresses fall within active delivery zones.
Road Trip Itinerary Planning
When travelers add stops to a route, travel apps calculate kilometer distances between waypoints to tally total travel distance.
Real Estate Search Filtering
Property portals measure distances from listed homes to city center coordinates so apartment hunters can filter rentals by commute proximity.
Fleet Dispatch Optimization
Dispatchers compute coordinate distances between open service tickets and available technicians to assign the nearest field worker to incoming jobs.
