Overview

AI-generated overview

Local MCP server that gives an assistant METAR and TAF aviation weather reports sourced from the FAA and NWS, with no API key needed.

What you can do
  • Retrieve METAR current-weather reports for aviation stations
  • Retrieve TAF terminal aerodrome forecasts
  • Pull the data from FAA and NWS sources without an API key
  • No individual tools are documented in the supplied listing, so exact parameters are unknown.
When to use it
Useful when you want an assistant to look up current or forecast aviation weather for airports or stations during flight planning, briefing or weather discussion.
Requirements
Runs as a local process over stdio, installed from the npm package @mrfentmen/aviation-weather-mcp, so Node.js and npm are needed. No authentication, environment variables or headers are declared. Network access is implied to reach FAA and NWS data.
Before you install
The server is marked desktop-only. Weather data comes from third-party FAA and NWS sources, so it may be delayed or unavailable and should not be the sole basis for flight decisions. No write actions or credentials are indicated.

Installation

In SourceWeft

  1. Open Aviation Weather Mcp in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.
