THE RISK

Critical Risk

Why deleteEvent needs a policy

This tool permanently removes event records from the athlete's training data. Deletion is irreversible and cannot be undone through normal operations. While the blast radius is limited to a single event (rather than bulk deletion via deleteBulkEvents), it still qualifies as Destructive rather than Write because the operation cannot be reversed.

From the tool's definition Tool name is 'deleteEvent' and description states 'Delete an event' – the verb 'delete' indicates irreversible removal of data.

Documented attack patterns abuse exactly the kind of access deleteEvent gives an agent:

POLICY

How to control deleteEvent

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 deleteEvent:

policy.json

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

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

Create a free account and register Intervals Icu MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
