  • list_origins

    Returns the departure airports (IATA) that have at least one priced weekend calendar, with the count of priced destinations per origin. Start here to learn what cheapest_weekends can answer at once. weekend_prices works for any airport pair and searches live when needed.

  • weekend_prices

    Every weekend of the next 12 months for one origin-destination pair, with the cheapest round-trip price per weekend Prices answer at once; weekends not priced yet are searched live during the call, the way a page visit searches them (usually 10-40 s, at most ~55 s). If the search

  • cheapest_weekends

    The cheapest weekends from one origin across every destination that has a calendar under these filters, sorted by price. Optional month filter (yyyy-mm). Takes the same filters as weekend_prices. This tool reads what is already priced; it does not search every destination. A dest

Common questions

Is weekendflights safe?

It passed 2 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.0) reached the registry 22 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.
