WHAT IT DOES

What update_asset does on ServiceNow MCP Server

RISK

Why update_asset is rated Medium

This tool modifies existing asset records in ServiceNow, which are reversible changes. The impact is medium severity because unauthorized updates to IT asset records could affect asset tracking, compliance, and inventory management, but the changes can be undone or corrected. The explicit '[Write]' label in the description provides high confidence in this categorization.

From the tool's definition Tool name 'update_asset' and explicit description 'Update an IT asset record' with '[Write]' classification indicate data modification.
