What can you do with this server?

The OctoTrip Flights server lets you search and compare real-time flight offers from multiple airlines and booking platforms worldwide — for free, with no login required. Key capabilities: * Search one-way or round-trip flights by specifying origin, destination, departure date, and optionally a return date * Flexible location input — accepts city names, airport names, or IATA codes (e.g., "Frankfurt", "JFK", "London Heathrow") * Filter by passengers — specify adults, children (ages 2–11), and infants (under 2) * Filter by cabin class — Economy or Business * Set preferred currency and language for results * Receive price-ranked results grouped by number of stops, with details on airline, flight numbers, alliance, aircraft type, departure/arrival times, layovers, total duration, and baggage info * Access affiliate booking links for each result (valid ~15 minutes) * Structured error handling for ambiguous locations, unresolved airports, invalid dates, or no available flights ⚠️ The server does not book flights, modify reservations, charge users, or store user data. Book promptly, as results are only valid for approximately 15 minutes due to real-time airline pricing.

Result Validity

Search results and booking links are valid for approximately 15 minutes. Flight prices are determined through a real-time bidding process and are not guaranteed beyond this window. If a user wants to book, they should do so promptly. For stale results, run a new search.

Error Responses

The server returns structured errors with suggestions:

airport_not_found -- airport could not be resolved. Try an IATA code, city name, or airport name.
disambiguation_needed -- multiple airports found (e.g. "New York" returns JFK, LGA). Pick one and retry.
invalid_date -- date format not recognized. Use YYYY-MM-DD, DD.MM.YYYY, or similar.
no_results -- no flights available for the given criteria. Try different dates or a nearby airport.

Inspect

Searches live flight offers between an origin and destination for given travel dates. Supports one-way (omit return_date) and round-trip searches with flexible passenger counts and cabin class. Use this when the user wants to compare available flights, airlines, prices, layovers, or booking links for a specific route. Do not use it for rental cars, hotels, trains, or general travel planning unless the user has flight-search intent. The tool queries external flight aggregator APIs in real time, returns price-ranked results grouped by number of stops, and includes affiliate booking links. Results and booking links are valid for approximately 15 minutes due to real-time airline pricing. It does not book flights, modify reservations, charge users, or store user data.

A4.6/5.0

Behavior5/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Beyond annotations (readOnlyHint, idempotentHint, destructiveHint), the description adds real-time external API querying, price-ranked results grouped by stops, affiliate booking links, and 15-minute validity. It also clarifies it does not book flights, modify reservations, or store user data.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is well-structured, starting with core function, then usage guidelines, then behavioral details. It is informative but slightly long; however, each sentence serves a purpose.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's complexity (10 parameters, real-time API, output with links and pricing), the description covers purpose, usage, behavioral traits, and limitations (15-minute validity). Output schema exists, so return values are covered. Complete for effective use.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% with each parameter described in the input schema. The description repeats that return_date can be omitted for one-way trips, which is already in the schema. No additional semantic depth beyond what the schema provides.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states it searches live flight offers between origin and destination for given dates, supports one-way and round-trip with flexible passengers and cabin class. It distinguishes itself from non-flight searches, making the purpose unambiguous.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Explicitly says 'Use this when the user wants to compare available flights...' and 'Do not use it for rental cars, hotels, trains...', providing clear when-to-use and when-not-to-use guidance.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

A4.6/5.0

Scored 2026-07-05 10:45 across 1 tool

Disambiguation5/5

With only one tool, there is no possibility of confusion between tools. The tool's purpose is clearly described and distinct.

Naming Consistency5/5

A single tool cannot be inconsistent. The name 'search' is a simple verb, but consistency is perfect by default.

Tool Count3/5

One tool feels thin for a server named 'OctoTrip Flights', which implies broader flight-related capabilities. The tool is well-defined, but the count is borderline for the apparent scope.

Completeness2/5

The server only provides flight search, lacking any booking, modification, or cancellation functionality. Agents cannot complete a flight-related task beyond searching, which is a significant gap for a flight server.
