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?"
