WHAT IT DOES

What delete_event does on Intervals Icu MCP Server

AI agents call delete_event to permanently remove resources in Intervals Icu MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

THE RISK

Critical Risk

Why delete_event needs a policy

This tool irreversibly deletes training events from the Intervals.icu fitness platform. Deletion cannot be undone, making it destructive rather than merely write-level. The severity is high because an AI agent could delete important training history or events, significantly impacting fitness tracking and training plans, though the blast radius is limited to a single athlete's events rather than system-wide data.

From the tool's definition Tool name is 'delete_event' and description states 'Delete event for an athlete from Intervals.icu'. The tool permanently removes data without reversibility.

POLICY

How to control delete_event

PolicyLayer is an MCP gateway — it sits between your AI agents and Intervals Icu MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for delete_event:

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "delete_event"
  ]
}

delete_event disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.
