Get weight measurements for a date range.
AI agents call get_weigh_ins to retrieve information from Mcp Garmin without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves historical weight measurement data within a specified date range. It performs no mutations, deletions, or external operations—purely a query operation on existing health metrics. The explicit 'read-only' designation in the server description and the consistent pattern of getter methods across all sibling tools confirm this is a Read category tool with low risk.
From the tool's definition Tool name 'get_weigh_ins' and description 'Get weight measurements for a date range' indicate data retrieval. Server description states 'read-only access' to health metrics.
