Click on "Deploy Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type @ followed by the MCP server name and your instructions, e.g., "@com.whichtrim/vehicle-records Has the 2021 Kia Telluride had any do-not-drive recalls?"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
An MCP server for U.S. vehicle records. Ask your assistant about a car and it gets the federal record, not a guess:
NHTSA recalls, with park-outside and do-not-drive advisories and completion rates
owner complaints, and the mileage at which owners reported problems
open defect investigations
manufacturer service bulletins, campaigns and warranty extensions, looked up by the number on the letter
diagnostic trouble codes, and which vehicles' records actually name them
EPA fuel economy, NCAP crash ratings, VIN decoding and trim-level prices where a press kit is on file
It covers every model year from 2016 on, plus recall campaigns going back further. The data is public: it comes from NHTSA, EPA and manufacturer press kits. It is republished at whichtrim.com and is free to use, with no key and no sign-up.
Remote (recommended). If your client supports remote MCP servers, point it at the URL. Nothing needs to be installed.
https://whichtrim.com/portal/mcpLocal (stdio). Some clients only launch local servers. For those, this package is a small bridge that has no dependencies: it forwards each JSON-RPC message to the URL above and passes the reply back. It requires Node 18 or later.

Tool | What it answers |
| Find model years by make, model and/or year. Returns the vehicle id the other tools take, plus each match's grade and recall count. |
| The full record for one model year: fuel economy, recalls, complaint counts and failure mileage, crash ratings, investigations, bulletins and trouble codes. |
| Every recall campaign for one model year, with advisories and completion rates. It says plainly that a recall applies to a build range, so only a VIN check can confirm that one specific car is affected. |
| Decodes a 17-character VIN against NHTSA's vPIC database and joins it to the record for that model year. |
| What a code such as P0420 means, and which model years' bulletins and complaints name it. |
| A service bulletin or campaign by its printed number (e.g. |
| Two model years side by side: economy or range, grade, recalls, complaints, crash rating and starting price. |
All seven tools are read-only.
"Has the 2021 Kia Telluride had any do-not-drive recalls?"
"What is GM bulletin N262570770 about, and which trucks does it cover?"
"Which cars' owners complain about P0420, and at what mileage?"
"Decode this VIN and tell me what's open on that model year: "
"Compare a 2024 RAV4 Hybrid with a 2024 CR-V Hybrid on reliability and running costs."
The bridge stores nothing and sends no telemetry. Each request goes only to whichtrim.com, which logs the tool name and response time and not your conversation. See the privacy page.
