WHAT IT DOES

What close_incident does on ServiceNow MCP Server

AI agents use close_incident 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 close_incident is rated Medium

This tool creates a state change in ServiceNow's incident management system by closing an incident record. While the action itself is reversible (incidents can be reopened), it represents a significant modification to operational data that affects incident lifecycle and tracking. Closing incidents can impact SLA tracking, reporting, and team workflows.

From the tool's definition Tool name 'close_incident' and description 'Close a resolved incident' explicitly modifies incident state. The requirement flag 'WRITE_ENABLED=true' confirms this is a write operation that changes data in ServiceNow.

RECOMMENDED RULE

The rule that runs close_incident 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 close_incident, this is the rule to start with:

close_incident Rate-limited

close_incident 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.
