Tools

This server runs locally, so its tools are listed by your MCP client once it starts.

Environment variables

NameDescription

ALLTRAILS_WS_PORT
Optional		fetchproxy concentrator port (default 37149, shared by the whole fetchproxy fleet — override only for local dev/tests).

Optional		Overrides the x-language-locale request header (default "en-US").
