Purpose

/vin-lookup pulls the complete dossier on any VIN: factory specs (year, make, model, trim, engine, transmission, MSRP), full listing history across all dealers with dates and prices, and an estimated current market value at 50K miles as a baseline.

The listing history is particularly valuable for trade-in decisions — you can see how many dealers have listed the vehicle, what each one asked, and how the price trended. Multiple dealer hops or steep price drops are red flags that a single price check would miss.

Arguments

VINrequired

17-character VIN. Required — command will prompt if not provided.

How It Works

Execution flow. MCP tool calls are shown inline on each step.

Profile Load

Load ZIP from profile for market anchoring. UK dealers are routed to use /price-check instead — VIN lookup is US-only.

VIN Decodedecode_vin_neovin

Decode VIN with include_generic=true to get full factory spec sheet: year, make, model, trim, body, engine, transmission, fuel type, MSRP.

Listing Historyget_car_history

Pull complete listing history for the VIN sorted by date descending — every dealer that has listed this unit, with price, DOM, and status.

Market Value Estimatepredict_price_with_comparables

Predict market value at 50,000 miles (note: provide actual mileage for precise estimate). Uses dealer ZIP from profile.

Limitations

US-only. UK dealers are redirected to /price-check with year/make/model.
Market value estimate uses 50,000 miles as default — provide actual odometer reading for accuracy.
Listing history only covers listings in the MarketCheck database — very recent inventory not yet indexed may not appear.
Some vehicles (especially recently new or private-sale only) may have no listing history.
