event_log_clear

THE RISK

Critical Risk

This tool permanently deletes Windows Event Log entries, which constitutes irreversible destruction of data. Event logs are critical for security auditing, compliance, and forensic investigation. An AI agent misusing this tool could destroy evidence of malicious activity, violate compliance requirements (SOC2, HIPAA, etc.), or hide system compromise.

From the tool's definition Tool name 'event_log_clear' and description 'Clear a Windows Event Log' indicate irreversible deletion of event log data. Clearing event logs destroys audit trails and forensic evidence that cannot be recovered.

HOW TO CONTROL EVENT_LOG_CLEAR

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

policy.json

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

event_log_clear 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 Mcp Windows — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
