Get detailed data for a specific exercise by ID. Can include samples and zones for detailed analysis.
AI agents call get_exercise to retrieve information from Polar 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 exercise data by ID from the Polar fitness API. It performs a read-only query of existing data with no side effects, modifications, deletions, or external operations triggered. The data returned is personal fitness information that could be sensitive but the tool itself only reads and does not alter state.
From the tool's definition Tool name 'get_exercise' and description 'Get detailed data for a specific exercise by ID' indicate a retrieval operation. The phrase 'Can include samples and zones for detailed analysis' confirms data querying without modification.
