WHAT IT DOES

What create_notification does on ServiceNow MCP Server

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

RISK

Why create_notification is rated Medium

This tool creates a new notification definition in ServiceNow, which is a reversible write operation. It creates configuration data (email notification rules) that can be modified or deleted later. While email notifications could potentially send messages to users based on their definition, the tool itself only creates the definition and does not execute the notification immediately.

From the tool's definition Tool name is 'create_notification' and description explicitly states 'Create a new email notification definition', indicating creation of a new data object. The requirement flag 'WRITE_ENABLED=true' further confirms this is a write operation.

create_notification Rate-limited

create_notification 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.
