WHAT IT DOES

What copy_template does on CloudStack MCP Server

AI agents use copy_template 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 copy_template needs a policy

This tool modifies infrastructure state by duplicating a template resource to a new location (zone), which is a reversible write operation. While it doesn't delete or execute arbitrary code, it creates new infrastructure state. It's not Execute because template copying is a standard management operation, not code execution.

From the tool's definition Tool name: 'copy_template'; description: 'Copy template to another zone'. The action creates or replicates a template artifact across infrastructure zones.
