AI agents call get_weigh_ins to retrieve information from Garmin Connect without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves existing health data (weigh-in history) within a specified time period. It has no side effects, does not modify, delete, or execute operations on the data. It is purely informational retrieval, placing it firmly in the Read category with low severity.
From the tool's definition Tool name and description indicate retrieval of historical weigh-in records: 'Get weigh-in records over a date range'. The verb 'Get' and passive data retrieval nature with no modification or deletion involved confirms read-only behavior.

{
"version": "1",
"default": "deny",
"tools": {
"get_weigh_ins": {}
}
