What it does

Airfare Brain is an MCP server, a connector that lets an AI assistant use it as a tool. It is hosted: an assistant connects to it over the internet, nothing to install.

From the publisher's description, Electra Index matched it to one capability: travel booking. That makes it a candidate for tasks such as book travel.

Facts come from the Official MCP Registry, as declared by the publisher. Capabilities are matched automatically (low confidence) and are not a test of the tool.

4 tools offered to AI assistants

  • get_capabilities · What Airfare Brain covers: airlines, how fees are researched and dated, what it does NOT do (no live fares, no booking), and the sister tool for car hire.
  • list_airlines · List every airline with a fee table: name, IATA code, the date its fees were checked, and its page.
  • airline_fees · One airline's published extra fees (bags, seats, priority, check-in, changes, payment), each with the price range, when bought (at booking / later / airport), how it is charged, its source URL and the date checked. Optionally filter by cate
  • true_cost · The true cost of a flight on one airline: the extras a person chooses (cabin bag, checked bag by kg, seat, priority, infants) for their party and trip, as the range the airline publishes, plus the fare if given. Also lists what costs more i

How we test: we open an MCP session and ask for the tool list, as an AI assistant would. We never run a tool and never send a key. Checked every few days. Method
