It searches live offers and hands back the cheapest option in each vehicle category with a link to book it — it does not book cars, modify reservations, charge users, or store user data. OctoTrip is free to use, and booking links carry affiliate attribution, with results ranked by price within each car category rather than by affiliate payout.
OctoTrip Rental Cars is a hosted MCP server that searches live rental-car offers for a pickup location and a rental period. It answers over a streamable HTTP endpoint at https://mcp.octotrip.app/rental-cars/mcp that any MCP client can point at, and it takes no API key.
- `search` accepts a city, airport, station, address, or landmark as the pickup point.
- Pickup and dropoff dates parse from YYYY-MM-DD, DD.MM.YYYY, or plain language.
- A separate dropoff location covers one-way rentals; pickup and dropoff times are optional.
- Results come back grouped by vehicle category, with the cheapest options in each, their cancellation policies, and a booking URL.
- Currency, response language, and driver age are request parameters, so the same rental can be quoted the way the traveller will pay for it.
No account and no API key — add the endpoint to your client config. Clients that speak only stdio bridge to it with `mcp-remote`. Rate limit: 1 request/second with burst capacity of 5.
One command — npx mcp-remote https://mcp.octotrip.app/rental-cars/mcp
