Trust breakdown (6 categories)

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 →

Endpoint Security74

The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one. See how to fix → View diagnostics → Partial
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 Usability42

AI-judged instruction clarity (good).Pass
Context-footprint check failed: tool/resource definitions use about 1072 tokens (~536/item across 2 items; 2 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 Management27

Stability observed for 8 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial

Tool Coverage98

100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
93% of tool parameters carry a description.Partial

Capabilities100

Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

Tool Tokens

search_flights ~984

Find the cheapest round-trip across a FLEXIBLE multi-month date window with a min/max trip length — e.g. "10–15 days, anytime Sep–Nov". Search a broad date window rather than requiring the traveler to choose exact dates first. First call the search_locations MCP tool for city or airport names, then pass each returned airport:AAA or city:AAA value unchanged as origin/destination (explicit legacy IATA codes remain supported). Add an earliest/latest date window and min/max trip duration; get back a ranked list of the cheapest fares (with booking links) plus a price verdict — an honest read of whether the cheapest fare is low, typical, or high versus the route's usual price, or unknown when we lack a usable typical-price band (a price-level read, not a buy-now-or-wait timing prediction). Non-economy requests may return representative Google Flights route-price evidence in metadata.route_price_check, but that evidence stays outside ranked results until it carries an exact seller booking action. Use it for any flight question where the dates are flexible or the user wants the cheapest time to fly. If metadata.refresh_hint is present, you may repeat the same call after the suggested delay to inspect a separate same-route/date/cabin price check. If you can wait longer for that best-effort cross-check, set verify=full. It uses a longer ~35s budget, but never treats a different airline, itinerary, gate, or booking URL as verification of the displayed offer. Provider failure, unavailability, or a spend cap can still return only cached indicators; always inspect metadata.freshness and metadata.route_price_check.

Input Output Examples

Name	Type	Req	Description
cabin	string	—	Cabin class: economy (default), premium_economy, business, or first. The bookable Travelpayouts calendar currently covers economy only. For a non-economy request, Google Flights may return representa…
ch	string	—	Acquisition channel tag (e.g. web, mcp, a campaign name). Encoded with the route into the affiliate link's sub_id so a future commission can be attributed to this channel in the Travelpayouts dashboa…
currency	string	—	Result currency, 3-letter ISO code UPPERCASE.
earliest	string	—	Earliest acceptable departure date (ISO YYYY-MM-DD). Required for a specific route; ignored in anywhere mode.
from	string	yes	Origin location. Use a legacy 3-letter code (SHA), an exact airport (airport:SHA), or an all-airports city (city:SHA). Required for every search, including to=anywhere.
latest	string	—	Latest acceptable return date for round-trip, or latest acceptable departure for one-way (ISO YYYY-MM-DD). Window from earliest must be ≤365 days. Required for a specific route; ignored in anywhere m…
max_days	integer	—	Maximum round-trip duration in days (return - departure); ignored for one-way and anywhere mode.
max_transfers	integer	—	Maximum number of transfers/layovers per leg. 0 = nonstop only, 1 = up to 1 stop, etc. Omit for no filter.
min_days	integer	—	Minimum round-trip duration in days (return - departure); ignored for one-way and anywhere mode.
one_way	boolean	—	If true, search one-way flights; return_date and duration_days will be null.
to	string	—	Destination location: a legacy code, airport:AAA, or city:AAA. Pass `anywhere` (or omit) to get the cheapest destinations from the origin instead of a specific route.
top_n	integer	—	Maximum number of results to return, sorted cheapest-first. Specific routes allow up to 50; anywhere mode returns at most 12.
verify	string	—	How hard to cross-check the top result's route, dates, and cabin against Google Flights (SerpApi). `false` (default): the check still runs automatically on a fresh search when the top isn't already a…

search_locations ~88

Resolve a city or airport name or code before searching flights. Returns typed values such as city:SHA to search every catalog airport in Shanghai or airport:SHA for Hongqiao only. Pass the selected value unchanged to search_flights. Ask the traveler when multiple results are plausible.
