faa-aircraft-registry-mcp-server

Overview

The entire US civil aircraft registry as an offline lookup server. Resolve a tail number to its aircraft, make/model, engine, year, and registered owner; search by owner, type, or state; decode manufacturer and engine codes to specs; and resolve registration status across active, deregistered, and reserved records.

The data is the FAA's Releasable Aircraft Database — the full registry published by the FAA Civil Aviation Registry as a public-domain bulk download (a US Government work, no copyright). There is no keyless live FAA registry API, so the server builds a local index from that download instead: MASTER → ACFTREF → ENGINE are pre-joined into an embedded SQLite + FTS5 index, and every coded field is decoded at query time. Queries hit that local index — keyless, no runtime network, no per-request rate limit.

The index is not bundled with the package. On first use the operator runs mirror:init to download and build it (see First-run setup). Owner name and address are redacted by default (see Owner-PII redaction).

Composes with live flight-tracking data: the Mode S (hex) code this server returns is the ICAO 24-bit address that OpenSky and similar feeds key on, so a tail number or transponder code seen in the air decodes here to its aircraft and status.

Tools

Five tools covering the registry — two exact-key lookups, two full-text searches, and one cross-file status resolver. Searches return decoded summaries with N-numbers (or 6–7-character reference codes) to drill into via the matching lookup.
