AI agents call get_gear_defaults 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 retrieves configuration data (default gear assignments) without modifying, deleting, or executing any operations. It has no side effects and presents minimal risk—the data returned is already public user settings. Classified as Read with low severity.
From the tool's definition Tool name 'get_gear_defaults' and description 'Get default gear assignments per activity type' indicate a retrieval operation. The verb 'Get' and lack of any modification, deletion, or execution language clearly indicate this is a query-only function.

PolicyLayer is an MCP gateway — it sits between your AI agents and Garmin Connect, and nothing reaches the server without passing your rules. This is the rule we recommend for get_gear_defaults:
{
"version": "1",
"default": "deny",
"tools": {
"get_gear_defaults": {}
}
}get_gear_defaults is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
