RECOMMENDED RULE

The rule that runs run_fix_script safely

PolicyLayer is an MCP gateway: it sits between your AI agents and NowAIKit — ServiceNow AI Toolkit, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For run_fix_script, this is the rule to start with:

run_fix_script Rate-limited

run_fix_script stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
