Get an overview of all health data including VO2 max, activities, sleep, and race predictions
AI agents call get_health_summary to retrieve information from Garmin Health 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 and aggregates existing health metrics from Supabase without creating, modifying, or deleting any data. It is a straightforward data query operation. Even if an AI agent calls this repeatedly or with different parameters, no side effects occur—only data is returned. No financial, destructive, or execution risks are present.
