WHAT IT DOES

What update_zone does on CloudStack MCP Server

AI agents use update_zone to create or update resources in CloudStack MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your CloudStack MCP Server environment.

WHY IT NEEDS A POLICY

Why update_zone needs a policy

This tool modifies zone configuration parameters but does not irreversibly delete data (not Destructive) or execute arbitrary code (not Execute). Zone updates are reversible configuration changes. While the blast radius could be significant if a zone configuration is incorrectly modified affecting multiple resources, the operation itself is Write-class.

From the tool's definition Tool name 'update_zone' combined with description 'Update zone configuration' indicates modification of infrastructure settings.
