fa_get_flights

Read-only

Retrieve recent, current, and scheduled flights for a flight designator, aircraft registration, or FlightAware flight ID to track a specific flight or aircraft.

Instructions

Get flights for an ident — a flight designator (e.g. UAL123, AAL100), aircraft registration (e.g. N12345), or fa_flight_id. Returns recent, current, and scheduled flights for that ident.

Input Schema

NameRequiredDescriptionDefault
endNoISO-8601 end of the time window
viewNoResponse shape: "compact" (default) drops fields the response already carries elsewhere; "full" returns every field this server understands. compact strips image/avatar URLs from the response; "full" returns FlightAware's payload untouched. No field projection: this server has no verified record of which FlightAware fields matter, and inventing one would risk dropping a field a caller needs.
identYesFlight designator, registration, or fa_flight_id
startNoISO-8601 start of the time window
cursorNoPaging cursor: the cursor query parameter of a previous response's links.next (passing the whole links.next value also works)
max_pagesNoMax pages to fetch, 1-20 (AeroAPI default: 1). Capped at 20 since AeroAPI bills per page.
ident_typeNoDisambiguate how `ident` is interpreted

TDQS

B3.3/5.0
Behavior3/5

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

Annotations already declare readOnlyHint and openWorldHint, so the safety profile is covered. The description adds the temporal scope of results (recent/current/scheduled), which is genuinely useful, but says nothing about pagination behavior, page-based billing, or result-size limits even though those materially affect a call.

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

Conciseness5/5

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

Two tight sentences, front-loaded with the verb and the ambiguity-prone ident argument; every clause earns its place.

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

Completeness3/5

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

For a 7-parameter, no-output-schema tool, the description covers the argument forms but omits the time-window/paging story that start, end, cursor and max_pages imply. Adequate rather than complete.

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 description coverage is 100% (including ident patterns, enum values, cursor semantics and the per-page billing cap on max_pages), so the schema already carries the parameter load. The description's ident examples (UAL123, N12345) are mildly reinforcing but add nothing the schema lacks.

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

Purpose4/5

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

States a specific verb ('Get') and resource ('flights') and enumerates the three accepted ident forms with examples, so an agent knows exactly what the tool retrieves. It does not, however, explicitly differentiate itself from near-siblings like fa_get_flight_history or fa_resolve_flight, which the ident-overloading makes necessary.

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

Usage Guidelines2/5

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

The description says what comes back ('recent, current, and scheduled flights') but never states when to pick this over fa_get_flight_history, fa_search_flights, or fa_resolve_flight. With 30+ siblings, the absence of any routing guidance leaves selection to inference.

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