WHAT IT DOES

What create_hr_case does on ServiceNow-MCP

AI agents use create_hr_case to create or update resources in ServiceNow-MCP, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your ServiceNow-MCP environment.

RISK

Why create_hr_case is rated Medium

This tool creates new data records (HR cases) in ServiceNow, which is a Write operation. The severity is high because creating HR cases can trigger business processes (leave requests, complaints, onboarding), impact personnel records, and have downstream consequences. However, it is Write (not Destructive) because HR cases can typically be modified or closed.

From the tool's definition Tool description states "Create a new HR Service Delivery case" with requirement "WRITE_ENABLED=true", indicating irreversible creation of a new case record in ServiceNow HR module.

RECOMMENDED RULE

The rule that runs create_hr_case safely

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

create_hr_case Rate-limited

create_hr_case stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
