LeaseCheetah for AI assistants

Last updated September 26, 2026

LeaseCheetah runs an MCP server, so an AI assistant can use it directly: find the lease offers car manufacturers publish, work out their real monthly cost, check whether a dealer’s quote is a good deal, list the franchised dealers nearest you, and — if you ask — pass your request for an offer to one of them, free. It works with Meta AI (Muse), ChatGPT, Claude and any other client that supports remote MCP servers.

Connecting it

  • With sign-in (needed to send a request to a dealer): https://mcp.leasecheetah.com/mcp/oauth
  • Without sign-in (looking things up only): https://mcp.leasecheetah.com/mcp

In your assistant, add a custom connector with one of those addresses and choose OAuth when asked how it signs in. In the Meta AI (Muse) mobile app, which asks for a Client ID, enter leasecheetah and leave the Client Secret blank. On the web you can leave both blank and the app registers itself. If Muse reports “Something went wrong” after you sign in, check Settings → Connectors: the connection has usually been saved.

Signing in

Sign-in asks for your name and email address, then emails you a 6-digit code to confirm the address is yours. There is no password and no account to create. Your name and email are what a dealer receives if you send them a request, and nothing is sent without you confirming it first. See the privacy policy for exactly what is kept.

What it can do

  • search_lease_offers — current offers filtered by brand, model, body style, powertrain, term or budget, cheapest real monthly cost first; pass a ZIP code for the prices advertised in your area.
  • get_model_offers — every current offer for one car, with its real monthly cost.
  • evaluate_lease_quote — compares a dealer’s quote with what the manufacturer is advertising for the same car.
  • lease_market_stats — this month across every tracked brand: the median payment overall and by body style, the cheapest and most expensive leases, and how lease terms are spread.
  • find_dealers — the brand’s franchised dealers nearest a ZIP code, up to five within 150 miles, from each manufacturer’s own dealer locator.
  • request_dealer_quote — the link to an offer’s page, where you can ask a dealer for a quote yourself.
  • send_to_dealer — passes your request for an offer to a dealer near you, with your name and verified email and a phone number if you give one. The only tool that sends anything.
  • search and fetch — the same offer data in the shape ChatGPT’s connectors expect.

Every answer about a specific car includes a photo of it, and a link to its page on leasecheetah.com.

Sending a request to a dealer

send_to_dealer works in two steps. The first sends nothing: it returns exactly what the dealer would receive — your name and email, the car, the dealer, and our published offer — for your assistant to show you. Only a second request carrying that confirmation sends it, and a confirmation for one set of details cannot send different ones. The dealer is asked to quote the offer the manufacturer publishes, never an assistant’s paraphrase of it. It goes to the nearest franchised dealer unless you choose another from the nearby list. The dealer replies through a LeaseCheetah forwarding address, not your own, and you get an email with a link that deletes your details whenever you like.

For reviewers

Any email address at review.leasecheetah.com is a review account: it signs in with the reviewer code given in our submission notes instead of an emailed one, and send_to_dealer runs every check and both confirmation steps for it but never sends anything to a dealer.
