Today is the operative word: we check Sparkflights every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

This endpoint answered with an authorization challenge. The server is running, but it did not say what kind of credentials it expects.

Available tools 2

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

deal

get_deal

One Sparkflights fare by the numeric id from search_deals: its itinerary, the price text of its fare page, its outbound and return flights, the date pairs its fare page lists with their prices, and its url, route_url and feed_url. A fare that is no longer live returns an error naming its route page.

deals

search_deals

Search flight fares Sparkflights has already found and verified, ranked by cost per mile against each market's limit. Not a live fare search: an empty result means no current verified fare matches. Each result has the price text of its Sparkflights fare page; url, the fare page; route_url, the route page, which lists the route's live fares and price history; and feed_url, the route's JSON feed of new fares.

Sparkflights — questions

Answers built from our own checks of this server.

What can Sparkflights do?

It exposes 2 tools, read directly from the server on our last check. Among them: get_deal, search_deals. 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 Sparkflights 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 351 ms. The bar chart above shows every period we have measured.

How do I connect Sparkflights?

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. You will need your own credentials: it refuses anonymous clients.

Does Sparkflights need an API key?

Yes. Every time we knock, Sparkflights answers with an authorization challenge instead of its tool list — that is how we know it is running and gated rather than broken. Bring your own credentials and it will talk.

How fast is Sparkflights?

It answers our handshake in 351 ms on average, which is faster than 39% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.

Is Sparkflights open source?

The code is open source: it is published under the MIT licence and 0 stars on GitHub. The licence covers the code in the repository, not the hosted service at sparkflights.com, which runs on its operator's own terms.
