Core

  • Pass
    Reachable

    Latest probe returned HTTP 200 in 1424 ms.

  • Pass
    Valid handshake

    protocolVersion 2025-06-18, serverInfo.name whichtrim.

  • Pass
    Lists tools

    tools/list returned 9 tools.

  • Pass
    Current protocol

    Negotiated 2025-06-18. The bar is 2025-06-18 or newer.

  • Pass
    HTTPS

    The endpoint URL is https.

Performance

  • Not measured
    Fast (p50)

    Median latency 1424 ms over 1 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    95th percentile 1424 ms over 1 samples in 7 days. The bar is 3000 ms. Need at least 20 samples.

  • Not measured
    Reliable (uptime)

    1 of 1 attempts returned a tool list in 30 days (100%). The bar is 99%. Need at least 30 samples.

  • 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.

    Every tool description is at least 20 characters.

  • Pass
    Valid input schemas

    Every inputSchema is a JSON Schema object.

  • Pass
    Parameters documented

    16 of 16 parameters have a description (100%). The bar is 80%.

  • Pass
    Safety hints

    Every tool sets readOnlyHint or destructiveHint.

Publisher

  • Pass
    Verified namespace

    Listed in the Official MCP Registry.

    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.

  • Pass

Capabilities

Tools 9

check_recalls

Every NHTSA recall campaign on file for one model year, with severity, park-outside and do-not-drive advisories and the reported completion rate. IMPORTANT: recalls apply to a build range, not to a model year, so this cannot establish whether one specific vehicle is affected — only a VIN check can: send the user to the WhichTrim recall report at https://whichtrim.com/vin/?vin=<VIN>, which narrows the campaigns to that VIN's engine, drive and build month.

Discovered
compare_vehicles

Two model years side by side on the figures that decide most purchases: fuel economy or EV range, Safety Signal grade, recalls, complaints, crash rating and starting price where a press kit is on file.

Discovered
decode_vin

Decode a 17-character VIN against NHTSA's vPIC database and join it to the WhichTrim record for that model year: year, make, model, engine, plant, plus the grade and recall campaigns on file.

Discovered
federal_cases

Federal lawsuits in the RECAP docket index (CourtListener, Free Law Project) that name a vehicle's manufacturer as a party and mention the model and a vehicle system — product-liability, warranty, lemon-law and class cases, newest first, with court, filing date, docket number, nature of suit and a link to each docket. Asked nightly by WhichTrim's build and cached, so the answer is as the index stood on the date given. A docket's presence says nothing about merits or outcome; state-court cases are not indexed.

Discovered
get_trims

Every trim of one model year as the manufacturer's own press kit states it: name, powertrain, drivetrain and MSRP, each trim's headline specs, which equipment is standard on which trims, and the warranty. Pass `trim` for one trim's full specification sheet (engine, dimensions, cargo, weights, brakes, wheels, tires) and its standard and optional equipment, with what it adds over the cheapest trim. Only model years with a press kit on file have trims — search_vehicles marks them.

Discovered
get_vehicle

The full published record for one model year: EPA fuel economy, NHTSA recalls, owner-complaint counts and the mileage at which owners reported problems, crash ratings, open investigations, service bulletins and the diagnostic trouble codes its record names.

Discovered
lookup_bulletin

A manufacturer service bulletin, service campaign, warranty extension or over-the-air notice by the number on the letter or the document (Hyundai 9D6, Kia SC199, '26-01-068H TSB', GM N262570770). Returns what NHTSA's summary says, the model years it names, every document filed under it with a verified link to NHTSA's PDF where one exists, and the page URL. These are NOT safety recalls — the answer says so.

Discovered
lookup_trouble_code

What a diagnostic trouble code (P0420, U0100, …) means where the OBD-II standard defines it, and — the part no other source publishes — which vehicles' federal record actually names it: how many manufacturer service bulletins and owner complaints mention it, and on which model years.

Discovered
search_vehicles

Find model years in the WhichTrim catalogue by make, model and/or year. Returns each match with its Safety Signal grade, recall count and page URL. Use this first to get the vehicle id that the other tools take.
