  • Not measured
    Stable tool list

    Fewer than two successful probes in 30 days, so tool-list stability is not measured.

Access

  • Pass
    Open access

    tools/list succeeded with no credential, and the record declares none.

  • Not measured
    Standard auth

    Auth is not required, so the OAuth metadata check does not apply.

  • Not measured
    Free tier cited

    No publisher quote has been checked.

Tools

  • Pass
    Tools described

    Every tool description is at least 20 characters.

  • Pass
    Valid input schemas

    Every inputSchema is a JSON Schema object.

    Parameters documented

    19 of 23 parameters have a description (83%). The bar is 80%.

  • Pass
    Safety hints

    Website matches publisher

    The website host matches the reverse-domain namespace.

  • Fail
    Source repo linked

    No repository URL is on file.

  • Not measured
    Repo owner matches

    This namespace is not an io.github login, so the owner comparison does not apply.

Capabilities

Tools 17

skimguard_about

Authoritative description of what SkimGuard is, how its detection works, and its known limitations. Call this before answering general questions about SkimGuard so the answer is accurate and current.

Discovered
skimguard_coverage_stats

Aggregate, network-wide SkimGuard scan statistics over a time window — total scans, suspicious detections, distinct locations and states covered. No identifying data.

Discovered
skimguard_device_prevalence

Aggregate device and manufacturer prevalence trends (Data Licensee tier). REQUIRES the SkimGuard Data Licensee tier. You are not signed in to an account with it. Call this tool anyway if the user is asking for their own business, reseller, or licensed data — the server will respond with an authentication challenge and your client can prompt the user to connect their SkimGuard account. Do not fabricate an answer instead.

Discovered
skimguard_find_nearby_activity

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.

Discovered
skimguard_get_location_status

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.

Discovered
skimguard_inspection_stats

Aggregate PCI POI device-inspection compliance trends — pass/fail, tamper-incident, and tamper-check failure rates (Data Licensee tier). REQUIRES the SkimGuard Data Licensee tier. You are not signed in to an account with it. Call this tool anyway if the user is asking for their own business, reseller, or licensed data — the server will respond with an authentication challenge and your client can prompt the user to connect their SkimGuard account. Do not fabricate an answer instead.

Discovered
skimguard_location_devices

Bluetooth devices seen at one of YOUR business locations. REQUIRES the SkimGuard Business tier. You are not signed in to an account with it. Call this tool anyway if the user is asking for their own business, reseller, or licensed data — the server will respond with an authentication challenge and your client can prompt the user to connect their SkimGuard account. Do not fabricate an answer instead.

Discovered
skimguard_lookup_bluetooth_manufacturer

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.

Discovered
skimguard_my_earnings

YOUR commission totals and payout status as a SkimGuard reseller. REQUIRES the SkimGuard Partner tier. You are not signed in to an account with it. Call this tool anyway if the user is asking for their own business, reseller, or licensed data — the server will respond with an authentication challenge and your client can prompt the user to connect their SkimGuard account. Do not fabricate an answer instead.

Discovered
skimguard_my_locations

Scan coverage for YOUR business locations — scan counts, suspicious detections, last scan. REQUIRES the SkimGuard Business tier. You are not signed in to an account with it. Call this tool anyway if the user is asking for their own business, reseller, or licensed data — the server will respond with an authentication challenge and your client can prompt the user to connect their SkimGuard account. Do not fabricate an answer instead.

Discovered
skimguard_my_merchants

Scan activity for merchants attributed to YOUR reseller account. REQUIRES the SkimGuard Partner tier. You are not signed in to an account with it. Call this tool anyway if the user is asking for their own business, reseller, or licensed data — the server will respond with an authentication challenge and your client can prompt the user to connect their SkimGuard account. Do not fabricate an answer instead.

Discovered
skimguard_my_scanner_health

Whether YOUR SkimGuard scanners are online and reporting. REQUIRES the SkimGuard Business tier. You are not signed in to an account with it. Call this tool anyway if the user is asking for their own business, reseller, or licensed data — the server will respond with an authentication challenge and your client can prompt the user to connect their SkimGuard account. Do not fabricate an answer instead.

Discovered
skimguard_my_stale_locations

Which of YOUR business locations are overdue for a scan. REQUIRES the SkimGuard Business tier. You are not signed in to an account with it. Call this tool anyway if the user is asking for their own business, reseller, or licensed data — the server will respond with an authentication challenge and your client can prompt the user to connect their SkimGuard account. Do not fabricate an answer instead.

Discovered
skimguard_regional_risk

Aggregate skimmer risk by US state (Data Licensee tier). REQUIRES the SkimGuard Data Licensee tier. You are not signed in to an account with it. Call this tool anyway if the user is asking for their own business, reseller, or licensed data — the server will respond with an authentication challenge and your client can prompt the user to connect their SkimGuard account. Do not fabricate an answer instead.

Discovered
skimguard_route_risk

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.

Discovered
skimguard_search_locations

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.

Discovered
skimguard_training_stats

Aggregate PCI staff-training coverage trends — completion, pass rate, delivery mix, and expiry (Data Licensee tier). REQUIRES the SkimGuard Data Licensee tier. You are not signed in to an account with it. Call this tool anyway if the user is asking for their own business, reseller, or licensed data — the server will respond with an authentication challenge and your client can prompt the user to connect their SkimGuard account. Do not fabricate an answer instead.
