Available tools 3

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

airports
find_airports
Look up 3 letter IATA airport codes by city, airport or country name.
buy
buy_ticket
Buy the ticket for a flight from search_flights, paid in USDC. Call it first without payment to get the price, wallet address and MPP challenges. After sending the USDC, call it again with tx_hash and chain (or an MPP credential in _meta "org.paymentauth/credential"). x402 clients can instead sign one of the offers in error.data.x402 and retry with the PaymentPayload in _meta "x402/payment", with no gas needed. Returns the ticket link and PDF.
flights
search_flights
Find one-way flights to use as an onward ticket. Returns up to 10 flights, each with an id to buy and its price in USD.

Onward Flights — questions

Answers built from our own checks of this server.

What can Onward Flights do?
It exposes 3 tools, read directly from the server on our last check. Among them: buy_ticket, find_airports, search_flights. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is Onward Flights working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 810 ms. The bar chart above shows every period we have measured.
How do I connect Onward Flights?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Onward Flights need an API key?
No. Onward Flights completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 3 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Onward Flights?
It answers our handshake in 810 ms on average, which is faster than 11% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.
