## Why create_business_rule is rated High

Business rules contain executable server-side JavaScript that runs automatically on database operations in ServiceNow. Creating a business rule doesn't just write data — it installs persistent executable logic that can affect all future record operations across the platform.

From the tool's own definition: "'Create business rules' — business rules in ServiceNow are server-side scripts that execute automatically when records are inserted, updated, deleted, or queried."

## Use case

AI agents invoke create_business_rule to trigger actions in ServiceNow MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

## Recommended policy (PolicyLayer)
