Opensky Overview
Opensky MCP server exposes live aircraft tracking and regional airspace summaries through the Pipeworx gateway. It uses a fallback chain of keyless ADS-B mirrors rather than the OpenSky Network itself, while preserving OpenSky field names and units for state vectors. Use it for current aircraft locations, ICAO24 lookups, and regional traffic counts; historical flight legs are explicitly unavailable. It can connect through a hosted streamable-HTTP endpoint or a local npm stdio bridge.
Primary Use Cases for Opensky:
- Find aircraft currently flying near a latitude and longitude
- Look up the live position of an aircraft by ICAO24
- Summarize civilian air traffic across a named region
- Build an agent workflow around OpenSky-shaped state vectors
