How to install Car Rental Brain in Claude DesktopDesktop app (MCP config)

Open your MCP config
macOS: ~/Library/Application Support/Claude/claude_desktop_config.json · Windows: %APPDATA%\Claude\claude_desktop_config.json

Add this server

json

{
  "mcpServers": {
    "car-rental-brain": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-remote",
        "https://app.carrentalbrain.com/mcp"
      ]
    }
  }
}

Why the wrapper?
This is a remote (HTTP) server and Claude Desktop only launches local processes, so mcp-remote proxies the connection. It will open a browser window if the server needs OAuth.
Restart Claude Desktop
The tools appear under the 🔌 menu once the app reloads.

How to install Car Rental Brain in Codex CLIOpenAI coding agent

Add to ~/.codex/config.toml

toml

[mcp_servers.car-rental-brain]
command = "npx"
args = ["-y", "mcp-remote", "https://app.carrentalbrain.com/mcp"]

Why the wrapper?
Codex runs MCP servers as local processes, so mcp-remote bridges this HTTP endpoint to stdio.
Run Codex
Codex loads MCP servers from config.toml on startup and exposes their tools to the agent.

What tools does Car Rental Brain expose? (6)

Read from the live server. Click any tool for its input schema.

get_capabilitiesWhat Car Rental Brain measures, how fresh it is, and which airports/countries are covered. Use first when unsure whether a place is covered.
list_airportsAirports we measure, with the typical rental price per day. Filter by country. Use to find an airport id or to list what is covered in a country.
airport_costsThe true cost of hiring a car at one airport: per-day price for the car alone, with a second driver, with full cover, automatic, no-deposit (from + typical); by pick-up month; second-driver fees; deposits; debit-card acceptance; desk closing times and out-of-hours fees; policies. Use when someone asks what car hire really costs at one airport, or about deposits, fees or desk hours there.
compare_airportsRank airports by real cost (car only / with driver / with cover), typical deposit, debit-card friendliness or late desk hours. Use for 'where in Spain is car hire cheapest in March?' or 'which airport is best for a debit card?'
supplier_termsPer supplier at an airport: typical price per day, second-driver fee, full-cover price, deposit held, whether the desk takes a debit card, and customers' desk review scores. Use when the person is choosing between suppliers at one airport or asks about a named supplier.
build_search_linkA link for the PERSON to open: live prices for their exact dates and needs, ranked by the total they will actually pay, where they can book. Use whenever the person has dates and wants to see or book cars.

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.

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

| Tool | What it answers | |---|---| | get_capabilities | What is measured, how fresh it is, which airports and countries are covered | | list_airports | Airports measured, with the typical price per day; filter by country | | airport_costs | One 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_airports | Rank airports by real cost, deposit, debit-card friendliness or late desk hours | | supplier_terms | Per supplier at an airport: price, second-driver fee, full-cover price, deposit, debit card, desk review scores | | build_search_link | A 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?"
