Aviation Weather MCP Server

Local setup required. This server has to be cloned and prepared on your machine before you register it in Claude Code.
1

Set the server up locally

Run this once to clone and prepare the server before adding it to Claude Code.

Run in terminal
pip install -r requirements.txt
python server.py
2

Register it in Claude Code

After the local setup is done, run this command to point Claude Code at the built server.

Run in terminal
claude mcp add aviation-weather -- python "<FULL_PATH_TO_AVIATION_WEATHER_MCP>/dist/index.js"

Replace <FULL_PATH_TO_AVIATION_WEATHER_MCP>/dist/index.js with the actual folder you prepared in step 1.

Real-time access to official aviation weather data from aviationweather.gov

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?"
