WHAT IT DOES

What create_business_rule does on ServiceNow MCP Server

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.

RISK

Why create_business_rule is rated High

Business rules in ServiceNow are server-side scripts that execute in response to database events (insert, update, delete, query). Creating a business rule means deploying arbitrary executable code into the platform that can run with elevated privileges on every matching record operation.

From the tool's definition "Create a new business rule" and "requires SCRIPTING_ENABLED=true" — business rules contain executable server-side scripts that run automatically on database operations

RECOMMENDED RULE

The rule that runs create_business_rule safely

create_business_rule Rate-limited

create_business_rule 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.
