Get weight measurements between specified dates
AI agents call get_weigh_ins 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 queries historical weight measurement data within a date range. It performs no side effects, creates no new data, executes no commands, and cannot be used to modify or delete records. This is a pure read operation on health metrics stored in Garmin Connect. While the data may be personal, exposure is limited to retrieval—the tool poses minimal risk of accidental misuse by an AI agent.
From the tool's definition Tool name 'get_weigh_ins' and description 'Get weight measurements between specified dates' indicate retrieval of existing data with no modification, deletion, or external action.
