WHAT IT DOES

What create_user does on ServiceNow-MCP

AI agents use create_user 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_user is rated Medium

This tool creates new user accounts in ServiceNow, which is a reversible write operation. It modifies the system by adding new data but does not execute arbitrary code, delete data irreversibly, or involve financial transactions. The severity is high because creating unauthorized user accounts could grant unwanted access to the system, compromise security, and impact multiple users.

From the tool's definition Tool name is 'create_user' and description states 'Create a new user account'. The requirement of 'WRITE_ENABLED=true' confirms this is a write operation that creates new data.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs create_user 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_user, this is the rule to start with:

create_user Rate-limited

create_user 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.
