Tools (7)

`nhtsa_decode_vin`read-only	Decode a Vehicle Identification Number to extract make, model, year, body type, engine, safety equipment, and manufacturing details. Pass a single 17-character VIN string, or an array of up to 50 VINs for batch decode. Partial VINs accepted — use * for unknown positions.
`nhtsa_get_safety_ratings`read-only	Get NCAP crash test ratings and ADAS feature availability for a vehicle. Use when the user specifically wants crash test stars, rollover risk, or wants to compare safety features across vehicles. NCAP data available from 1990+, best coverage for 2011+.
`nhtsa_get_vehicle_safety`read-only	Get a comprehensive safety profile for a vehicle. Combines NCAP crash test ratings, recalls, and complaint summary into a single response. Use as the default when asked about vehicle safety, reliability, or purchase decisions.
`nhtsa_lookup_vehicles`read-only	Look up valid makes, models, and vehicle types in NHTSA's database. Use to resolve ambiguous vehicle names, find correct make/model spelling, or discover what models a manufacturer produces.
`nhtsa_search_complaints`read-only	Search consumer safety complaints filed with NHTSA for a specific vehicle. Returns a component breakdown over all matching complaints plus a paginated slice of the most recent complaints. Use for common problems, failure patterns, or owner-reported issues.
`nhtsa_search_investigations`read-only	Search NHTSA defect investigations from the ODI flat file — covering Preliminary Evaluations (PE), Engineering Analyses (EA), Defect Petitions (DP), Recall Queries (RQ), Audit Queries (AQ), and additional ODI types. make, model, and component are structured filters against the investigation record's vehicle associations. All filters are ANDed. Use nhtsaId to fetch one investigation by its exact ID — including the investigationId nhtsa_search_recalls returns for a campaign. Investigations may link to a resulting recall campaign via recallCampaign.
`nhtsa_search_recalls`read-only	Search recall campaigns by vehicle or campaign number. Use for specific recall lookups, recall history for a vehicle, or looking up a known campaign number.
