Mcp Metar

daedalus/mcp-metar

Pulls live METAR and TAF aviation weather reports from ICAO airport codes. Exposes three tools: get_metar for current conditions, get_taf for terminal forecasts, and get_airport_weather for both in one call. You'd reach for this when building flight planning tools, aviation chatbots, or weather briefing assistants that need real airport weather data. The Python package works standalone or as an MCP server. Pass it any four-letter ICAO code like KJFK or EGLL and get back the raw weather strings pilots use. Clean implementation with test coverage and type checking. MIT licensed, so you can drop it into commercial aviation apps without licensing headaches.
