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
- Runs setuptools.build_meta at install time, a recognised build step with no custom scripting around it. View diagnostics → Pass
- 0 of 33 dependencies flagged as unhealthy. View diagnostics → Pass
Provenance & Transparency97
- Source repository is publicly reachable at the declared URL. View diagnostics → Pass
- Cryptographically verified build provenance (signed, bound to ThiagoJacobLannes/google-flights-mcp). View diagnostics → Pass
- Clear OSI-approved license (MIT).Pass
- Actively maintained (last published 3 days ago).Pass
- Disclosure check failed: no security disclosure policy was found in the source repository. See how to fix → Fail
Schema Quality & AI Usability56
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 796 tokens (~265/item across 3 items; 3 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management13
- Stability observed for 4 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage67
- 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
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 3 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 supported MCP spec version (2025-11-25); the latest is 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 →
airport_search ~78
Resolve a city or airport name to IATA code(s), e.g. "Lisbon" -> LIS. Args: query: A city name, airport name, or 3-letter IATA code. limit: Maximum number of matches to return (default 5).

| query | string | yes | – |

cheapest_dates ~308
Find the cheapest day(s) to fly within a date window (price-calendar style). Runs one search per candidate departure day in the window (capped at 21 days — neither of this server's data sources expose a real bulk price-calendar endpoint) and returns each day's cheapest fare, sorted by price ascending. Args: destination: Destination airport IATA code. start_date: First candidate departure date, YYYY-MM-DD. end_date: Last candidate departure date, YYYY-MM-DD (inclusive; max 21 days after start_date). origin: Origin airport IATA code. Defaults to Lisbon (LIS). trip_length: Nights for a round trip, applied to every departure day in the window. Omit to price one-way fares. adults, children, infants: Passenger counts (see search_flights). cabin_class: "economy" | "premium" | "business" | "first". currency: ISO currency code. Defaults to EUR. max_stops: Maximum stops to allow. Omit to allow any.

search_flights ~364
Search flight prices and options on Google Flights. Args: destination: Destination airport IATA code (e.g. "GRU"). If you only have a city name, call airport_search first. departure_date: Outbound date, YYYY-MM-DD. origin: Origin airport IATA code. Defaults to Lisbon (LIS) if omitted. return_date: Return date YYYY-MM-DD to search a round trip; omit for one-way. For round trips, each result's price is Google's estimated round-trip total for that outbound flight paired with its cheapest matching return — stops/duration/legs describe the outbound only. Open booking_link to pick the exact return flight. adults: Number of adult passengers (default 1). children: Number of child passengers (default 0). infants: Number of lap infants, under 2 with no own seat (default 0). cabin_class: "economy" | "premium" | "business" | "first". currency: ISO currency code. Defaults to EUR. max_stops: Maximum stops to allow (0 = nonstop only, 1 = up to one stop, etc.). Omit to allow any number of stops. sort_by: "price" (default, ascending) or "duration" (ascending).
