Category Maps and Location
How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. How we score → Why this is hard to score →
Supply Chain Security100
- No malware found by supply-chain analysis.Pass
- No known CVEs affecting this package version or its production dependencies.Pass
- No install/post-install scripts declared.Pass
- 0 of 13 dependencies flagged as unhealthy. View diagnostics → Pass
Provenance & Transparency100
- Source repository is publicly reachable at the declared URL. View diagnostics → Pass
- Cryptographically verified build provenance (signed, bound to victorlane/Flyan). View diagnostics → Pass
- Clear OSI-approved license (MIT).Pass
- Actively maintained (last published 78 days ago).Pass
- Publishes a security disclosure policy (SECURITY.md).Pass
Schema Quality & AI Usability67
- AI-judged instruction clarity (good).Pass
- Tool/resource definitions use about 402 tokens (~100/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 Management100
- No destabilizing schema changes in the last 30 days.Pass
Tool Coverage71
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 0% of tool parameters carry a description.Fail
- Structured output schemas are declared (100% of tools); any adoption earns full credit.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 4 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a current MCP spec version (2026-07-28).Pass

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_per_day ~98
Cheapest fare per day for one route across a single calendar month. ``month`` is the first of the month in ISO format (``YYYY-MM-01``). Powers "what's the cheapest day in July to fly DUB->BCN" style prompts. Days with no flight or no price come back with ``price=None``.
| Name | Type | Req | Description |
|---|---|---|---|
| destination | string | yes | – |
| month | string | yes | – |
| origin | string | yes | – |
| Name | Type | Req | Description |
|---|---|---|---|
| result | array | yes | – |
No examples provided.
explore_destinations ~78
Every destination Ryanair flies to from ``origin``, grouped by country. Returns ``{country_code: [{iata, name, city, region}]}``. No fare lookup, just the network. Good for answering "what countries can I reach from X" or "does origin fly to destination at all".
| Name | Type | Req | Description |
|---|---|---|---|
| origin | string | yes | – |
Structured output declared, but exposes no named fields.
No examples provided.
find_anywhere_under ~78
Cheapest fares from ``from_airport`` to *anywhere* under ``max_price``. Useful for "where can I go for under £50 this weekend" style prompts.
| Name | Type | Req | Description |
|---|---|---|---|
| from_airport | string | yes | – |
| from_date | string | yes | – |
| max_price | integer | yes | – |
| to_date | string | yes | – |
| Name | Type | Req | Description |
|---|---|---|---|
| result | array | yes | – |
No examples provided.
find_flights ~148
Search Ryanair one-way fares. ``from_airport`` and ``to_airport`` are 3-letter IATA codes (e.g. ``DUB``). ``destination_country`` is a lowercase ISO2 code (e.g. ``es``, ``gb``); uppercase silently returns no fares. Dates are ISO format (``YYYY-MM-DD``) and bound a *departure window*: the API returns the cheapest fare per route per day inside the window.

Flyan scores 92 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 5 November 2026. It declares no install or post-install scripts. Its build provenance is signed and verified. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.
What tools does the Flyan MCP server expose?
Flyan exposes 4 tools: find_flights, find_anywhere_under, explore_destinations, cheapest_per_day. Their descriptions and schemas cost roughly 402 tokens of context every time the server is loaded.
Is the Flyan MCP server still maintained?
Flyan is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
