Manual setup required. The maintainer's config contains paths only you know - edit the placeholders below before adding it to Claude Code.
1

Prepare the server locally

Run this once before adding it to Claude Code.

pip install -r requirements.txt
python server.py
2

Register it in Claude Code

claude mcp add aviation-weather -- python /path/to/server.py

Replace any placeholder paths in the command with the real path on your machine.

What it does

  • Access current airport weather observations (METARs) worldwide
  • Retrieve 24-30 hour terminal aerodrome forecasts (TAFs)
  • Fetch pilot reports (PIREPs) for in-flight conditions like turbulence and icing
  • Get aviation weather warnings and advisories (SIGMETs/AIRMETs)
  • Lookup airport station details including coordinates and elevation

Aviation Weather MCP Server

A hosted MCP (Model Context Protocol) server that gives Claude direct access to real-time aviation weather data from aviationweather.gov — no web searching needed.

Features

  • METARs — Current airport weather observations worldwide
  • TAFs — Terminal aerodrome forecasts (24-30 hour forecasts)
  • PIREPs — Pilot reports of in-flight conditions (turbulence, icing, etc.)
  • SIGMETs/AIRMETs — Aviation weather warnings and advisories
  • Station Info — Airport/station lookup with coordinates and elevation

Data Source

All data comes from the Aviation Weather Center (AWC) API at aviationweather.gov. This is the official FAA/NWS source — free, no API key required.

How It Works

This server uses:

  • FastMCP (Python) for MCP protocol handling
  • Streamable HTTP transport for remote access
  • Render for hosting (always-on web service)

Once deployed, add it as a custom connector in Claude Chat and Claude can directly query aviation weather data.

Setup

Deploy to Render

  1. Push this repo to GitHub
  2. Create a Web Service on render.com
  3. Connect to this GitHub repo
  4. Configure:
    • Runtime: Python 3
    • Build Command: pip install -r requirements.txt
    • Start Command: python server.py
  5. Deploy

Add to Claude Chat

  1. Go to Claude Chat Settings → Connectors
  2. Click "Add custom connector"
  3. Enter your Render URL + /mcp (e.g., https://your-app.onrender.com/mcp)
  4. Name it "Aviation Weather" or similar
  5. Start asking Claude about METARs, TAFs, and PIREPs!

Example Prompts

Once connected, try asking Claude:

  • "What's the current METAR for KJFK?"
  • "Get the TAF for Tucson International (KTUS)"
  • "Are there any PIREPs for turbulence near Chicago?"
  • "Show me current SIGMETs for convection"
  • "What's the weather at KORD, KLAX, and KSFO?"
