Purpose

An appraisal is only as strong as its market anchor. Without knowing where a vehicle sits in the current competitive landscape — how its price compares to the cheapest and most expensive competing units, what percentage of the market it undercuts, and whether it is priced at franchise retail or independent wholesale — any valuation is a guess dressed up as analysis.

Competitive Pricer runs dual price predictions (franchise retail and independent wholesale proxy) against live competing listings to give appraisers the full price spectrum. It calculates percentile rank, median, and distribution statistics for the competitive set, and shows the retail-to-wholesale spread — the core metric for trade-in offers, insurance claim settlements, and estate midpoint valuations. CPO vehicles get separate certified and non-certified market prices with the premium quantified.

How It Works

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

01
Profile Load

Reads marketcheck-profile.md for ZIP, radius, country, and min_comp_count. US appraisers get VIN decode and dual price predictions; UK appraisers get active comp search only with comp median as the price anchor.

02
VIN Decodedecode_vin_neovin

Calls decode_vin_neovin to confirm year, make, model, trim, body type, drivetrain, engine, and transmission. Presents confirmed specs to user before pricing — assumed trims produce unreliable comparables.

↔ Parallel Execution

03a
Franchise (Retail) Pricepredict_price_with_comparables

Calls predict_price_with_comparables with dealer_type=franchise. This represents full retail market value — what a franchised dealer would list the vehicle for. The primary anchor for insurance replacement cost claims.

03b
Independent (Wholesale-Proxy) Pricepredict_price_with_comparables

Parallel call to predict_price_with_comparables with dealer_type=independent. Provides wholesale-oriented context — what independent dealers pay and list at. The anchor for trade-in offers and auction buying decisions.

04
Competitive Listings Pullsearch_active_cars

Calls search_active_cars with YMMT, ZIP, radius=75mi, sorted by price ascending, rows=15. Returns the full competitive set across all dealer types with price, miles, DOM, dealer name, dealer type, and distance.

05
Price Position Calculation

If a subject or asking price is provided, calculates percentile rank in the competitive set, distance to cheapest and most expensive unit, median/mean market price, and count of competing units within ±5% of the subject price.

06
Dual Market Price Output

Presents franchise (retail) and independent (wholesale) market prices with the spread in dollars and percentage. Appraiser selects the appropriate benchmark based on appraisal purpose: insurance = retail, trade-in = wholesale, estate = midpoint.

Limitations

  • US-only for dual pricing (decode + predict). UK returns comp median only.
  • Wholesale-proxy pricing via independent dealer_type is an estimate — actual auction prices may differ by 3–8%.
  • CPO detection requires VIN history pull or user confirmation; adds one API call.
  • Market distribution stats (percentile, stddev) require the full competitive set — thin markets (< 5 comps) reduce statistical reliability.
