search_car_deals
Search for car deals across multiple sources (Cars.com, Autotrader, KBB). Returns listings with prices, mileage, deal ratings, and links.
LABSCO SUMMARY
Three marketplaces in one answer — with the coverage gaps written down.
The README publishes a per-source table rather than claiming parity: Cars.com returns everything including full CARFAX filters, while deal rating and those filters are limited on Autotrader and KBB. It scrapes live pages, so results track whatever those sites render today and break when they change.
What it is
A Node server that scrapes three used-car marketplaces in parallel with Puppeteer and normalises what comes back into one list. Each listing carries price, mileage, dealer, a heuristic deal rating and the source it came from.
What you get
- One search across Cars.com, Autotrader and KBB, or a subset you name —
search_car_deals - Make and model are required; ZIP,
yearMin,yearMax,priceMax,mileageMaxandmaxResultsnarrow it down - CARFAX-style filters —
oneOwner,noAccidents,personalUse— fully supported on Cars.com, partial on Autotrader and KBB - A heuristic deal rating per listing, plus dealer name and a direct link back to the listing page
Requirements
Node.js v16 or higher and a local Chrome or Chromium, which Puppeteer drives. If Puppeteer cannot find the browser, point PUPPETEER_EXECUTABLE_PATH at the binary. No account and no API key. Run it as a Node process against src/server.js. The package.json names car-deals-mcp 1.0.0 and declares a bin for it, a name npm does not have.
Setup effort
One command — npx -y github:SiddarthaKoppaka/car_deals_search_mcp
USE CASES
01
Shopping one model across every listing site at once
Give make, model and a ZIP and get price, mileage and dealer for matching cars from all three sources side by side, instead of running the same search in three tabs.
02
Filtering out fleet and accident cars before you look
Set oneOwner, noAccidents and personalUse. Expect these to bite hardest on Cars.com results — the other two sources support them only partially.
03
Checking whether a price you were quoted is reasonable
Search the same model with a priceMax and mileageMax near the car you are considering and read the deal ratings on what comes back.
