Available components
How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security74
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one. See how to fix → View diagnostics → Partial
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability73
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 925 tokens (~132/item across 7 items; 7 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management37
- Stability observed for 11 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 7 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 8 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities60
- Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28. See how to fix → Fail
How do I install the WhichTrim vehicle records MCP server?
WhichTrim vehicle records is a hosted endpoint at https://whichtrim.com/portal/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
check_recalls ~102
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 at nhtsa.gov/recalls can.
| Name | Type | Req | Description |
|---|---|---|---|
| id | string | yes | Vehicle id, e.g. 2021_kia_telluride. |
No output schema declared.
No examples provided.
compare_vehicles ~123
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.
| Name | Type | Req | Description |
|---|---|---|---|
| a | string | yes | Vehicle id for the first car, e.g. 2021_kia_telluride. Get one from search_vehicles. |
| b | string | yes | Vehicle id for the second car, e.g. 2021_honda_pilot. Get one from search_vehicles. Must be a different id from `a`. |
No output schema declared.
No examples provided.
decode_vin ~67
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.
| Name | Type | Req | Description |
|---|---|---|---|
| vin | string | yes | A 17-character VIN. |
No output schema declared.
No examples provided.
get_vehicle ~87
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.
| Name | Type | Req | Description |
|---|---|---|---|
| id | string | yes | Vehicle id, e.g. 2021_kia_telluride. Get one from search_vehicles. |
No output schema declared.
No examples provided.
lookup_bulletin ~195
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.
| Name | Type | Req | Description |
|---|---|---|---|
| make | string | – | The make, if known (hyundai, chevrolet). A number filed under several makes returns each without it. |
| number | string | yes | The number as printed: a campaign id (9D6, SC199) or a bulletin/document number (26-01-068H, T-SB-0141-26, 00-03-10-002J). |
No output schema declared.
No examples provided.
lookup_trouble_code ~89
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.
| Name | Type | Req | Description |
|---|---|---|---|
| code | string | yes | A trouble code, e.g. P0420. |
No output schema declared.
No examples provided.
search_vehicles ~109
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.
| Name | Type | Req | Description |
|---|---|---|---|
| limit | integer | – | Maximum results (default 10, max 40). |
| query | string | yes | Make and/or model, e.g. 'kia telluride' or 'rav4'. |
| year | integer | – | Restrict to one model year. |
No output schema declared.
No examples provided.
