🟢 Read-only🟡 Write🔴 Delete⚪ Unknown
🟢skimguard_get_location_status(placeId, days, response_format)

Look up SkimGuard card-skimmer scan status for a location by its Google Place ID. Returns how recently the location was scanned, how many scans it has, and whether any suspicious Bluetooth devices were detected. Use this to answer "is this gas station / ATM / store safe to use my card at?". Returns "not publicly tracked" for locations with no public scan data (including private residences, which are deliberately excluded). Side effect: if the Place ID is one SkimGuard has never seen, it is added to SkimGuard's own public location registry so the next nearby scan can attach to it. That writes to SkimGuard data only — never anything you or the user own — so this tool is read-only from the caller's perspective.

🟢skimguard_find_nearby_activity(latitude, longitude, radius_meters, days, limit, ...)

Find locations near a latitude/longitude that SkimGuard users have scanned recently, with suspicious-detection counts. Use for "any skimmers reported near me?". Only publicly visible locations are returned; private residences are excluded.

🟢skimguard_lookup_bluetooth_manufacturer(company_code, response_format)

Resolve a Bluetooth SIG company identifier to a manufacturer name and SkimGuard risk rating. Accepts decimal (76) or hex (0x004C). Useful for explaining what a device seen in a scan actually is.

Input Schema

  "type": "object",

}
🟢skimguard_search_locations(query, latitude, longitude, limit, days, ...)

Find a location by NAME or address (e.g. "Shell on Riverside, Austin TX", "Chase ATM near Union Square") and get its SkimGuard card-skimmer scan status. Use this when you know what a place is called but do not have its Google Place ID — it resolves the name first, then reports scan status for each match. Pass latitude/longitude when you know roughly where the user is; it sharply improves matching for common brand names. Locations with no scan data are reported as unknown, never as unsafe.

    "query": {

🟢skimguard_route_risk(polyline, corridor_meters, lookahead_meters, response_format)

Given a series of route points, report locations along that stretch of road with recent suspicious activity or stale scan coverage. IMPORTANT: this checks the road AHEAD, not a whole trip — at most 20 km of the supplied route is examined, and the response says how much was actually checked (examinedMeters / truncated). For accurate results pass real route geometry from a directions provider; passing only a start and end point checks a straight line between them, which will not follow the actual road. TO COVER A LONGER TRIP: split the route geometry into consecutive 20 km segments and call this tool once per segment, then combine the results — that is the supported way to check a full drive. A 500 km trip is about 25 calls, which fits inside the anonymous rate limit. Do NOT report a route as clear unless you have covered all of it this way; say which portion you checked.
