[Car Rental Brain]

Car Rental Brain MCP server

The real cost of car hire, for AI assistants. Second-driver fees, deposits, debit-card acceptance, desk hours and what excess cover really costs, measured at 120+ airports in Europe, the UK and the US, plus a link to live prices ranked by the total a person will actually pay.

Free. No API key. No login. Read-only.

MCP endpoint (streamable HTTP):

https://app.carrentalbrain.com/mcp

Listed in the official MCP Registry as com.carrentalbrain/car-rental-brain. Website: carrentalbrain.com · Agent page: carrentalbrain.com/ai

Why it exists

Car-hire search shows the headline price. The bill at the desk is different: a second driver adds a fee, the desk blocks a deposit on the card, many desks refuse debit cards, some close before a late flight lands, and the desk sells its own excess cover. Car Rental Brain measures these from its own repeated searches and answers with the numbers, so an assistant can say what a rental will really cost - not just what it is advertised at.

Tools

ToolWhat it answers
get_capabilitiesWhat is measured, how fresh it is, which airports and countries are covered
list_airportsAirports measured, with the typical price per day; filter by country
airport_costsOne airport's real cost: car only, with a second driver, with full cover, automatic, no-deposit; by pick-up month; deposits; debit cards; desk hours and out-of-hours fees
compare_airportsRank airports by real cost, deposit, debit-card friendliness or late desk hours
supplier_termsPer supplier at an airport: price, second-driver fee, full-cover price, deposit, debit card, desk review scores
build_search_linkA link for the person: live prices for their exact dates and needs, ranked by the total they will pay, where they can book

Every answer is dated and comes from measured searches, never estimates presented as fact.

Example questions

  • "What does it really cost to hire a car at Faro Airport for a week in November with two drivers?"
  • "Which Spanish airport is cheapest for car hire in March?"
  • "I only have a debit card - where can I pick up a car in Portugal?"
  • "My flight lands at 23:30 in Malaga - which desks are still open?"
  • "Is the desk's excess cover cheaper than buying full coverage in advance at Lisbon?"

The same tools are available as a plain JSON API (e.g. https://app.carrentalbrain.com/api/v1/get_capabilities) - see carrentalbrain.com/ai.

How the numbers are made

Each airport is searched repeatedly across trip lengths and pick-up months; a report is published only once enough searches agree. Second-driver fees are the suppliers' own quoted fees (a fee nobody publishes is never counted as free). Desk excess-cover prices come only from each supplier's own published price list, with the source and the date read. Full method: carrentalbrain.com/methodology.

Affiliate disclosure

Car Rental Brain is free. Booking happens on DiscoverCars through the link the tools return, and Car Rental Brain earns a commission on bookings, at no extra cost to the person booking. Results are ranked by the total the person will pay, never by commission.

Privacy

The tools take no personal data and need no account. Searches are logged without names or contact details. Privacy policy: carrentalbrain.com/privacy.
