WHAT IT DOES

What create_csm_case does on ServiceNow-MCP

AI agents use create_csm_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_csm_case is rated Medium

This tool creates a new case record in ServiceNow's Customer Service Management module. While reversible (cases can be deleted/archived), it modifies system state by inserting a new record. The moderate severity accounts for potential spam/noise generation or customer confusion if misused by an agent, but lacks the irreversibility of destructive operations or financial impact of payment tools.

From the tool's definition Tool name 'create_csm_case' and description 'Create a new Customer Service case' explicitly indicate record creation. Description includes '(requires WRITE_ENABLED=true)' confirming write operation.

RECOMMENDED RULE

The rule that runs create_csm_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_csm_case, this is the rule to start with:

create_csm_case Rate-limited

create_csm_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.
