WHAT IT DOES

What update_vulnerability does on ServiceNow MCP Server

AI agents use update_vulnerability 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 update_vulnerability is rated Medium

This tool modifies vulnerability records reversibly by changing state, notes, and dates. It does not delete data (would be Destructive) nor execute arbitrary code (would be Execute). However, severity is high because misuse could suppress or delay critical security remediation by falsifying vulnerability states or acceptance notes, potentially leaving systems exposed to known threats.

From the tool's definition Tool name 'update_vulnerability' and description 'Update a vulnerability entry (state, risk acceptance notes, remediation date)' indicate modification of existing security vulnerability records.

RECOMMENDED RULE

The rule that runs update_vulnerability safely

PolicyLayer is an MCP gateway: it sits between your AI agents and ServiceNow MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For update_vulnerability, this is the rule to start with:

update_vulnerability Rate-limited

update_vulnerability 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.
