Get the authenticated athlete
AI agents call strava_get_athlete_zones to retrieve information from Strava MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves data about the authenticated athlete's zones (such as heart rate or power zones used in fitness tracking). It performs a read-only query against the Strava API with no side effects, no data modification, no code execution, and no destructive capability. The blast radius of misuse is minimal—it only exposes the authenticated user's own fitness zone configuration data.
From the tool's definition Tool name is 'strava_get_athlete_zones' and description states 'Get the authenticated athlete' — this is a retrieval operation that queries user profile/zone data without modifying or executing operations.
