## Tools
- nhtsa_get_vehicle_safety (Nhtsa Get Vehicle Safety) - 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. Endpoint: https://nhtsa.caseyjhand.com/mcp
- nhtsa_search_recalls (Nhtsa Search Recalls) - 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. Endpoint: https://nhtsa.caseyjhand.com/mcp
- nhtsa_search_complaints (Nhtsa Search Complaints) - 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. Endpoint: https://nhtsa.caseyjhand.com/mcp
- nhtsa_get_safety_ratings (Nhtsa Get Safety Ratings) - 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+. Endpoint: https://nhtsa.caseyjhand.com/mcp
- nhtsa_decode_vin (Nhtsa Decode Vin) - 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. Endpoint: https://nhtsa.caseyjhand.com/mcp
- nhtsa_search_investigations (Nhtsa Search Investigations) - Search NHTSA defect investigations (Preliminary Evaluations, Engineering Analyses, Defect Petitions, Recall Queries). All filters are ANDed — each additional filter narrows results. The make, model, and query filters all search investigation subject/description text (there are no structured make/model fields in the investigations dataset). First query may be slow (~10s) while the investigation index loads; subsequent queries use a cached index. Endpoint: https://nhtsa.caseyjhand.com/mcp
- nhtsa_lookup_vehicles (Nhtsa Lookup Vehicles) - 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. Endpoint: https://nhtsa.caseyjhand.com/mcp
