Get training effect data for a specific activity
AI agents call get_training_effect 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 training effect metrics from Garmin Connect for an activity that has already been recorded. It performs a read-only query operation with no side effects on the data. The user's fitness data is already in the system and this tool simply fetches a specific data point.
From the tool's definition Tool name 'get_training_effect' and description 'Get training effect data for a specific activity' indicate a retrieval operation with the verb 'Get', which queries existing data without modification.
