Install

How do I install the Piratefly Flight Price Judge MCP server?

Piratefly Flight Price Judge is a hosted endpoint at https://piratefly.com/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

MCP tools · 4 exposed · ~397 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Tool Tokens
cheapest_months ~89

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.

NameTypeReqDescription
destinationstringyesDestination CITY NAME, e.g. "Tokyo". Airport codes are not accepted.
originstringyesOrigin CITY NAME, e.g. "Milan". Airport codes are not accepted.

No output schema declared.

No examples provided.

flight_price_verdict ~126

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.

NameTypeReqDescription
destinationstringyesDestination CITY NAME, e.g. "Tokyo". Airport codes are not accepted.
originstringyesOrigin CITY NAME, e.g. "Milan". Airport codes are not accepted.

No output schema declared.

No examples provided.

watched_routes ~99

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.

NameTypeReqDescription
destinationstring–Optional: only routes whose destination city contains this text.
originstring–Optional: only routes whose origin city contains this text.

No output schema declared.

No examples provided.

when_to_book ~83

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