server_service_restart · ArcGIS MCP: Risk & Policy

WHAT IT DOES

What server_service_restart does on ArcGIS MCP

AI agents invoke server_service_restart to trigger actions in ArcGIS MCP. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why server_service_restart needs a policy

Restarting a server service is an Execute-class action: it runs an operation whose effects depend on which service is targeted. The blast radius is high because restarting critical services can cause extended downtime, disrupt users, and potentially cause data loss if in-flight transactions are interrupted. While not permanently destructive or financial, it causes significant operational disruption.

From the tool's definition Tool name 'server_service_restart' indicates restarting a server service, which triggers an external operation with side effects (service downtime, interruption of operations).
