Nothing serious here today
Today is the operative word: we check WhichTrim vehicle records every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Read directly from the server with tools/list, grouped by what they act on.
If a tool disappears, we record the date.
lookup
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.
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.
compare
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.
decode
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.
federal
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.
recalls
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.
trims
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.
vehicle
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.
vehicles
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.

How MCP servers expose tools in the first place →
Is WhichTrim vehicle records working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 727 ms. The bar chart above shows every period we have measured.
How do I connect WhichTrim vehicle records?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does WhichTrim vehicle records need an API key?
No. WhichTrim vehicle records completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 9 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is WhichTrim vehicle records?
It answers our handshake in 727 ms on average, which is faster than 11% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.
