Get comprehensive activity statistics and counts
AI agents call get_activity_stats to retrieve information from Garmin 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 queries existing activity data from Garmin Connect without modifying, deleting, or executing any operations. It falls squarely within the Read category. The severity is low because activity statistics are non-sensitive personal fitness data with minimal blast radius if misused—an AI agent could retrieve stats but cannot alter training plans, delete data, or make financial transactions.
From the tool's definition Tool name 'get_activity_stats' and description 'Get comprehensive activity statistics and counts' indicate retrieval of data with no modification or execution. Activity statistics are historical metrics derived from fitness tracking.
