Delete a workout from Garmin Connect Permanently removes a workout from your Garmin Connect workout library. Args: workout_id: ID of the workout to delete (get IDs from get_workouts)
AI agents call delete_workout to permanently remove resources in Garmin MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool permanently deletes user fitness data (workouts) from Garmin Connect. Deletion is irreversible and cannot be undone, making it Destructive rather than Write. While a single workout deletion has limited blast radius (high severity rather than critical), the permanent nature of the operation and potential for accidental or malicious bulk deletion of user health records justify this classification.
From the tool's definition Tool name is 'delete_workout' and description explicitly states 'Permanently removes a workout from your Garmin Connect workout library.' The use of 'Permanently removes' and 'Delete' indicates irreversible deletion of user data.
Documented attack patterns abuse exactly the kind of access delete_workout gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Garmin MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for delete_workout:
{
"version": "1",
"default": "deny",
"hide": [
"delete_workout"
]
}delete_workout disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.
