Available components
How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security57
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation not fully verified: no authorisation is required to call this server, and 4 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe. See how to fix → View diagnostics → Unverified
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability78
- AI-judged instruction clarity (excellent).Pass
- Tool/resource definitions use about 459 tokens (~114/item across 4 items; 4 tools + 0 resources), lean.Pass
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management27
- Stability observed for 8 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 4 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 5 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities60
- Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28. See how to fix → Fail
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.

No change was recorded against any check on this day. Stability & Change Management went from 7 to 10. That category is still filling its 30-day observation window: 2 days of observed history at the previous scan, 3 at this one. The score rises as the window fills, whether or not the server changes.

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 →
cheapest_months Which months are cheapest for this route ~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.
| Name | Type | Req | Description |
|---|---|---|---|
| destination | string | yes | Destination CITY NAME, e.g. "Tokyo". Airport codes are not accepted. |
| origin | string | yes | Origin CITY NAME, e.g. "Milan". Airport codes are not accepted. |
No output schema declared.
No examples provided.
flight_price_verdict Is this flight price good right now? ~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.
| Name | Type | Req | Description |
|---|---|---|---|
| destination | string | yes | Destination CITY NAME, e.g. "Tokyo". Airport codes are not accepted. |
| origin | string | yes | Origin CITY NAME, e.g. "Milan". Airport codes are not accepted. |
No output schema declared.
No examples provided.
watched_routes Which routes Piratefly can judge ~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.
| Name | Type | Req | Description |
|---|---|---|---|
| destination | string | – | Optional: only routes whose destination city contains this text. |
| origin | string | – | Optional: only routes whose origin city contains this text. |
No output schema declared.
No examples provided.
when_to_book How far ahead to book this route ~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?".
| Name | Type | Req | Description |
|---|---|---|---|
| destination | string | yes | Destination CITY NAME, e.g. "Tokyo". Airport codes are not accepted. |
| origin | string | yes | Origin CITY NAME, e.g. "Milan". Airport codes are not accepted. |
