Alltrails

Alltrails MCP Server was a Model Context Protocol (MCP) server built to provide programmatic access to hiking trail data from AllTrails. It allowed users to search for trails by national park, retrieve detailed trail information (such as difficulty, length, elevation gain, route types, and more), and integrate with MCP-compatible clients for trip planning and outdoor activity research. This project is now deprecated after being taken down due to violation of AllTrails' Terms of Service, but remains archived for reference.
