WHAT IT DOES

What create_script does on FortiManager MCP Server

WHY IT NEEDS A POLICY

Why create_script needs a policy

'Create_script' likely creates a script object that can later be executed on firewalls, placing it in the Execute or Write category. Given the context of firewall management and that scripts imply execution capability, Execute is the most appropriate category.
