THE RISK

Low Risk

Why generate_audit needs a policy

This tool reads and analyzes security configuration and state to produce an audit report. It retrieves data without modifying anything. However, severity is medium because the audit report could expose sensitive security vulnerabilities, credentials, configurations, or architectural details of the n8n instance that could be exploited if accessed by a malicious actor.

POLICY

How to control generate_audit

PolicyLayer is an MCP gateway — it sits between your AI agents and n8n Workflow Builder MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for generate_audit:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "generate_audit": {}
  }
}

generate_audit is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
