WHY IT NEEDS A POLICY

Why add_devices_bulk needs a policy

This tool creates or modifies device configurations in FortiManager at scale. While not immediately destructive (changes are reversible), bulk device addition poses significant risk if misused by an AI agent—potentially adding unauthorized devices, misconfiguring network access, or disrupting firewall policy enforcement across many systems.

From the tool's definition Tool name 'add_devices_bulk' indicates bulk addition of devices; sibling tools like 'add_device', 'add_model_device', 'assign_package', and 'assign_template_group' all perform write operations on FortiManager.
