Which flight MCP server should I use?

Run more than one. Kiwi and OctoTrip search different inventory, and an assistant that can compare them gives a better answer than either alone.

Can my AI assistant book the flight?

No. These servers return live options and booking links; the booking happens with the provider, under their terms.

Flight MCP servers you can connect to an AI assistant

MCPHub runs three flight MCP servers live — Kiwi Flights, OctoTrip Flights, Flight Emissions — each monitored for uptime and reachable through one connection, with no per-server setup. Search live fares and booking links, or estimate a flight’s CO₂, from inside your assistant. Flights is the best-served category in the ecosystem and still the one where sources disagree most, which is why we run more than one.
