`@pipeworx/mcp-nhtsa` via Pipeworx remote gateway (https://gateway.pipeworx.io/nhtsa/mcp) — 15 calls across all 6 tools, 100% success, p50=500ms (network-bound).
6 tools:
decode_vin({vin})— decode any VIN to make/model/year/body/engine/safety-features/plantget_makes()— all vehicle brands (cars + motorcycles + ATVs + UTVs)get_models({make, year})— all models for a make and yearget_recalls({make, model, model_year})— official NHTSA safety recallsget_complaints({make, model, model_year})— owner-filed safety complaintsget_safety_ratings({make, model, model_year})— NCAP 5-star crash-test ratings
Key gotchas:
- ⚠️ `get_complaints` structured output has EMPTY `component` and `date_complaint_filed` fields — the data is present in text content but not in structuredContent. Ford Explorer 2020 returned 1,141 complaints with empty component/date fields
- ⚠️ `get_models` returns ALL vehicle types: Honda 2023 returns 108 models (Accord, Civic, Gold Wing, CRF450R, Pioneer 1000, Ruckus, etc. — cars + motorcycles + ATVs + UTVs)
- ⚠️ Invalid make returns `count: null` (not 0, not error) — different from valid make with no recalls (count: 0)
- ⚠️ Not all vehicles have safety ratings: Tesla Model Y 2023 returns count=0 with note "not all vehicles are tested"
- ⚠️ VIN check digit validation: synthetic VINs trigger Error Code 1 "Check Digit does not calculate properly" but still return decoded data
- ⚠️ Invalid VIN returns structured error codes with
all_attributes.Error Code: "6,7,11,400"and helpful error text (incomplete VIN, invalid characters, etc.) - Tesla Model 3 2020 has 20 recalls (FSD, Autopilot, rolling stop, seat belts, TPMS, air bags, brakes, etc.)
- Toyota Camry 2024 has 2 rating variants (AWD and FWD) — both 5-star across all categories
- Honda Civic 2021: overall=5, frontal=5, side=5, rollover=5
decode_vinreturns extensiveall_attributesobject with 50+ fields (ADAS features, brake types, lighting, wheelbase, etc.)- Gateway has 100 req/day anonymous rate limit (shared across all Pipeworx gateways per IP)
