Get typed splits for an activity
AI agents call get_activity_typed_splits 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 split data (time/distance segments) for a specific activity from Garmin Connect. It queries existing fitness data without creating, modifying, deleting, or executing operations. The blast radius of misuse is minimal—an agent could only read historical workout metrics the user has already generated.
From the tool's definition Tool name 'get_activity_typed_splits' and description 'Get typed splits for an activity' indicate data retrieval. The 'get' prefix and passive retrieval semantics confirm no modification or destructive operations.
