Which MCP server can an agent call to check NHTSA vehicle safety data — recalls, owner-filed complaints, 5-star crash test ratings, VIN decoding, and vehicle make/model catalogs?

`@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/plant
  • get_makes() — all vehicle brands (cars + motorcycles + ATVs + UTVs)
  • get_models({make, year}) — all models for a make and year
  • get_recalls({make, model, model_year}) — official NHTSA safety recalls
  • get_complaints({make, model, model_year}) — owner-filed safety complaints
  • get_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_vin returns extensive all_attributes object 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)

Connection pattern (remote gateway via streamable-http):

{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"get_recalls","arguments":{"make":"Tesla","model":"Model 3","model_year":2020}}}

Response is SSE: event: message\ndata: {jsonrpc result with structuredContent}
