@pipeworx/aviationstack

Aviationstack MCP — global flight tracking + airport / airline / route reference data. Free tier: 100 req/month.

Part of Pipeworx — an MCP gateway connecting AI agents to 1476+ live data sources.

Tools

flights(flight_iata?, flight_icao?, dep_iata?, arr_iata?, airline_iata?, flight_status?, limit?, offset?) — real-time + scheduled flights
airports(search?, iata_code?, icao_code?, limit?, offset?) — airport database (~10k airports)
airlines(search?, iata_code?, icao_code?, limit?, offset?) — airline database
cities(search?, iata_code?, country_iso2?, limit?) — city → primary airport mapping
countries(search?, country_iso2?, limit?) — country reference
routes(dep_iata?, arr_iata?, airline_iata?, flight_number?, limit?) — scheduled routes

Auth

Platform key: gateway env PLATFORM_AVIATIONSTACK_KEY
BYO: ?_apiKey=<key> after registering at https://aviationstack.com/signup/free

Free-plan limits

Only the flights endpoint works on the free tier. airports, airlines, cities, countries, routes return HTTP 403 function_access_restricted. Upgrade to Basic (~$50/mo) to unlock them. Free plan is HTTP-only (no https) — the pack already uses http://.

Data source

http://api.aviationstack.com/v1/ — access_key query param.

Quick Start

Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):

config.json

{
  "mcpServers": {
    "aviationstack": {
      "url": "https://gateway.pipeworx.io/aviationstack/mcp"
    }
  }
}

What this endpoint actually serves

tools/list at https://gateway.pipeworx.io/aviationstack/mcp returns the tools in the table above plus the shared Pipeworx meta-tools — ask_pipeworx, discover_tools, search_within, remember/recall and the rest of the gateway-wide set. So the tool count you see is larger than this table: a single-pack endpoint currently lists roughly 30 shared tools alongside the pack's own. The connection's initialize response states its exact scope, and is the authoritative answer for a given day.

This is deliberate, not multiplexing by accident. The meta-tools are what let a scoped connection answer a question this pack does not cover — via ask_pipeworx, which routes across the whole catalog — without you adding a second MCP server. There is currently no way to mount a pack endpoint without them; if the extra schemas cost you more context than the routing is worth, connect to the full gateway once rather than to several pack endpoints.

Or connect to the full Pipeworx gateway to get every pack's tools listed directly, instead of just this one's:

config.json

{
  "mcpServers": {
    "pipeworx": {
      "url": "https://gateway.pipeworx.io/mcp"
    }
  }
}

Both URLs reach the same gateway and the same 1476+ data sources. The only difference is which pack's tools are listed directly; ask_pipeworx reaches all of them from either one.

Using with ask_pipeworx

Instead of calling tools directly, you can ask questions in plain English — this works on the pack endpoint above as well as on the full gateway:

Code

ask_pipeworx({ question: "your question about Aviationstack data" })

The gateway picks the right tool and fills the arguments automatically.
