Click on "Install Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type
@followed by the MCP server name and your instructions, e.g., "@Aviation Weather MCP ServerWhat's the current METAR and TAF for KJFK?"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
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.

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?"
