About mcp-metar

mcp-metar is an MCP server for aviation weather data, for users who need airport observations and forecasts. It provides separate METAR and TAF lookups, plus a combined lookup by ICAO code.

Key features

  1. 01Fetch current METAR by ICAO code
  2. 02Fetch TAF forecast by ICAO code
  3. 03Retrieve METAR and TAF together

Use cases

  1. 01Check current weather at an airport
  2. 02Review an airport's TAF forecast

MCP support

It exposes tools to MCP-compatible clients for fetching METAR, TAF, or both for an airport identified by ICAO code.

Configuration

Local server config is the same for every client. Copy it into your client’s MCP config file.

mcp.json · Universal config
{
  "mcpServers": {
    "daedalus-mcp-metar": {
      "command": "uvx",
      "args": [
        "mcp-metar"
      ]
    }
  }
}
Run commanduvx mcp-metar

Local servers need a runtime on your machine (e.g. Node.js 18+). Config file locations differ by client; see your client’s docs.

Local servers expose tools only once running on your machine, and the maintainer has not provided a tool list.

Install

pip install mcp-metar

Usage

from mcp_metar import get_metar, get_taf, get_airport_weather

# Get current METAR for an airport
metar = get_metar("KJFK")
print(metar)

# Get TAF forecast
taf = get_taf("KJFK")
print(taf)

# Get both METAR and TAF
weather = get_airport_weather("KJFK")
print(weather["metar"])
print(weather["taf"])

MCP Server

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

{
  "mcpServers": {

      "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

From what the protocol is to installing your first server, these answers cover most first questions.

An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
