## Why update_ci is rated Medium

The tool modifies existing CMDB records (Configuration Items), which is a core asset tracking system in ServiceNow. While updates are reversible (Write not Destructive), unauthorized changes to CMDB entries could corrupt infrastructure documentation, affect compliance records, or disrupt service delivery workflows.

From the tool's own definition: "Tool name 'update_ci' indicates modification of Configuration Items in ServiceNow's CMDB. The 'update' verb and 'ci' (Configuration Item) designation, combined with the server's CMDB capabilities, confirms this performs reversible data modifications."

## Use case

AI agents use update_ci 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.
