Tool names and descriptions exactly as the server reported them on Nov 13, 2026. The maker wrote them, not us; we show them as plain text.
search_empty_legsFinds current empty-leg flights by origin and/or destination (city, IATA/ICAO code, country, US state, region or area such as Greek Islands), dates, passengers, budget and aircraft class. Returns up to 20 offers with route, date, aircraft, seats, indicative price, a voidjet link
get_empty_legCurrent details of one offer by the ref returned by search_empty_legs. available=false means the offer is no longer listed.
get_service_infoReturns voidjet's own answers to questions about costs, costs before a binding contract, contract partner, what happens after an inquiry, price binding, cancelled empty legs, how voidjet is funded, who receives the user's data and how fast providers reply. Use it instead of guess
report_unmet_needRecords a need voidjet cannot serve, for when the user wants voidjet to know about it: e.g. no offer on the route, a return flight, pets, instant booking. Takes 1-5 categories and optional route, dates, passengers and budget; no personal data. Helps voidjet decide what to add.
request_inquiryPrepares an inquiry for one offer, for when the user has asked to inquire and given their email. voidjet emails the user a link; nothing is forwarded to the provider until the user opens it and sends the pre-filled form on voidjet.io within 48 hours. name, phone and message are o
request_charter_quoteRequests confirmed charter prices from partner Villiers for the route of a charter_alternative, for when the user has seen its price range, asked for confirmed prices and given their email. NOT an empty leg: a regular charter; voidjet receives a fee from the partner. voidjet emai
create_flight_alertSets up an email alert for new empty legs on a route or from a place, for when the user asks to be notified and gives their email. voidjet emails a confirmation link; the alert becomes active only after the user clicks it (double opt-in, valid 7 days). Needs origin or destination

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.
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.
The registry does not list a required key, though some servers ask you to sign in on first use.
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.
The GitHub repo last changed –, and the latest version (1.1.0) reached the registry 35 days ago.
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 on the web (full MCP on Business and above; Pro read-only).
