WHAT IT DOES

What close_change_request does on ServiceNow MCP Server

AI agents use close_change_request 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_change_request is rated Medium

Closing a change request is a reversible modification operation that changes the status and properties of an existing record. While significant (it finalizes workflow state), it is not destructive because the record persists and can theoretically be reopened or the change tracked. This qualifies as Write rather than Destructive.

From the tool's definition Tool description explicitly states 'Close a change request' with 'close code and notes', which modifies the state of a change request record. Requires 'WRITE_ENABLED=true', indicating it performs a write operation.

RECOMMENDED RULE

The rule that runs close_change_request safely

close_change_request Rate-limited

close_change_request 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.
