Aviation Weather MCP Server is answering right now. Last checked 14 min ago. 740 installs a week from npm. It exposes 5 tools. Last commit 10 Sep 2026.
Fetch METARs, TAFs, PIREPs, and domestic SIGMETs from the NWS Aviation Weather Center.
Every tool that appeared, vanished or quietly changed what it asks for. Recorded since 13 August 2026. No other catalogue keeps this.
Today is the operative word: we check Aviation Weather MCP Server every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

This one needs environment variables set before it will start:
MCP_HTTP_HOST (The hostname for the HTTP server.), MCP_HTTP_PORT (The port to run the HTTP server on.), MCP_HTTP_ENDPOINT_PATH (The endpoint path for the MCP server.), MCP_AUTH_MODE (Authentication mode to use: 'none', 'jwt', or 'oauth'.), MCP_LOG_LEVEL (Sets the minimum log level for output (e.g., 'debug', 'info', 'warn').), AWC_BASE_URL (Base URL for the AWC Data API. Useful for testing against a mock or staging instance.), AWC_TIMEOUT_MS (Per-request timeout in milliseconds (1000–60000).).
The author declared them in the registry entry; get the values from the project itself.
