create_asset · ServiceNow- MCP: Risk & Policy

WHAT IT DOES

What create_asset does on ServiceNow-MCP

AI agents use create_asset 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.

WHY IT NEEDS A POLICY

Why create_asset needs a policy

This tool creates new asset records in ServiceNow's CMDB, which is a write operation. It modifies data by adding new records but is reversible (assets can be deleted or updated). The severity is medium because creating assets could lead to inventory confusion, billing errors, or configuration management issues if misused by an AI agent, but the effect is not irreversible like deletion would be.

From the tool's definition Tool name 'create_asset' and description 'Create a new IT asset record' indicate creation of data. The '[Write]' label in the description confirms this is a reversible data modification operation.
