Available tools 4

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

cheapest

cheapest_months

The departure months ranked by observed median price for a route, with the median of each. Answers "when is it cheapest to go" with measured data instead of seasonal folklore.

flight

flight_price_verdict

Answers "buy now or wait?" for a route, from 90 days of observed prices: verdict, percentile of today's cheapest fare against its own history, median, all-time low, and sample size. This is not a flight search: it judges a price. No other public source computes it, because it needs the price history, not today's snapshot.

watched

watched_routes

Lists the routes Piratefly observes daily and can therefore judge. Call this first, or after any answer saying a route is not watched, to find out what can be asked. Filter by origin and/or destination city (partial city name is fine) or omit both for the full list.

when

when_to_book

How many days before departure this route has historically been cheapest, from our own observations. Answers "am I booking too early or too late?".

Piratefly MCP — questions

Answers built from our own checks of this server.

What can Piratefly MCP do?

It exposes 4 tools, read directly from the server on our last check. Among them: cheapest_months, flight_price_verdict, watched_routes, when_to_book. 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 Piratefly MCP working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 87 of 91 checks got a reply (95.6%), average response time 360 ms. The bar chart above shows every period we have measured.

How do I connect Piratefly MCP?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Piratefly MCP need an API key?

No. Piratefly MCP completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 4 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Piratefly MCP?

It answers our handshake in 360 ms on average, which is faster than 45% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
