What is the MCP MCP server?

MCP server for METAR/TAF aviation weather data. Exposed over MCP by the mcp mcp server, that capability becomes something an assistant can invoke while it works, not something you go and do afterwards.

What it actually does

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

Its toolset

Everything the assistant can do here goes through one of these:

  • 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

Adding it to your client

mcp-metar on PyPI is all you need. Most clients run it directly, so configuration is a few lines and a restart.

When to reach for it

Plenty of developer tooling servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. MCP's toolset — get_metar, get_taf, get_airport_weather — is a fair guide to whether it matches your workflow. It is maintained by daedalus; worth a glance at recent repository activity before you build anything load-bearing on it.

SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.

Caveats

  • It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
  • MCP clients confirm each tool call by default. Leave that on until you have watched what the mcp mcp server does with a few real requests.

How to install the MCP MCP server

{
  "mcpServers": {
    "mcp-metar": {

Configuration as documented by the project. Restart the client after saving.

Example prompts to try

  • Use MCP to get metar.
  • Use MCP to get taf.
  • Use MCP to get airport weather.

Frequently asked questions

It connects MCP to MCP-compatible AI assistants such as Claude and Cursor, exposing 3 tools (get_metar, get_taf, get_airport_weather) that the assistant can call on your behalf. Instead of copying data back and forth by hand, the assistant works with MCP directly.
