What data sources does this MCP server use for METAR and TAF?

The server fetches real-time METAR (Meteorological Aerodrome Report) and TAF (Terminal Aerodrome Forecast) data from standard aviation weather sources. Check the repository documentation for specific data provider details and update frequency.

Do I need an API key or authentication to use this server?

The registry metadata does not specify required environment variables or API keys. Refer to the GitHub repository (io.github.daedalus/mcp-metar) for setup instructions and any authentication requirements.

What airport codes does this server support?

The server supports standard ICAO airport codes (e.g., KJFK, EGLL, KSFO). Most major airports worldwide are included; consult the documentation for coverage details or limitations.

Can I get historical METAR data or only current observations?

The server provides real-time METAR observations and TAF forecasts. For historical weather data, you may need to integrate a separate aviation weather archive or check if the server supports time-range queries in its full documentation.

How often is the METAR and TAF data updated?

METAR reports are typically issued every hour (or more frequently during significant weather), and TAF forecasts are updated regularly. Exact refresh intervals depend on the underlying data source; see the repository for SLA details.
