AI agents call get_primary_training_device 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 retrieves device information from Garmin Connect without creating, modifying, or deleting data. It is a straightforward read operation that queries existing configuration data about training devices. The blast radius of misuse is minimal—an agent could access device details but cannot alter settings, delete data, or trigger actions.
