## Why update_record is rated Medium

ServiceNow update operations modify existing data but do not irreversibly delete it, placing this in Write category. Severity is high because an AI agent with unvalidated access could maliciously alter critical business records, configurations, or CI data across the CMDB or other tables. The OAuth 2.1 authentication and Tokyo+ version suggest production systems are at risk.

From the tool's own definition: "Tool name 'update_record' in ServiceNow MCP Server context indicates modification of existing records. Sibling tools include 'create_record', 'delete_record', and 'create_update_set', confirming this server manages data lifecycle operations."

## Use case

AI agents use update_record 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.
