MCP Server

This package provides an MCP server that can be used with MCP-compatible clients. Configure your client with:

{
  "mcpServers": {
    "mcp-metar": {
      "command": "mcp-metar",
      "env": {}
    }
  }
}

Available Tools

  • get_metar: Fetch current METAR weather data for an airport by ICAO code
  • get_taf: Fetch TAF (Terminal Aerodrome Forecast) for an airport by ICAO code
  • get_airport_weather: Fetch both METAR and TAF for an airport by ICAO code
