MOST DANGEROUS TOOLS

High Risk

The most dangerous Claude Code Notification Hooks tools

Write · Low auto_notify_if_appropriate The tool writes notification events to the system but produces no permanent side effects beyond informing the user. Write · Low send_error_notification This tool creates transient notifications and triggers sound events on the user's desktop/system. Write · Low send_task_complete_notification This tool creates notifications as a side effect, constituting a Write operation—it generates new data artifacts (notifications) in the user's notification system.

4 of Claude Code Notification Hooks's 4 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.

POLICY

How to control Claude Code Notification Hooks

PolicyLayer is an MCP gateway — it sits between your AI agents and Claude Code Notification Hooks, and nothing reaches the server without passing your rules. These are the rules we recommend:

Rate limit write operations

{
  "auto_notify_if_appropriate": {
    "limits": [
      {
        "counter": "auto_notify_if_appropriate_per_hour",
        "window": "hour",
        "max": 30,
        "scope": "grant"
      }
    ]
  }
}

Prevents bulk unintended modifications from agents caught in loops.
