WHAT IT DOES

What add_url_to_filter does on Fortimanager

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

RISK

Why add_url_to_filter is rated Medium

The tool adds a URL to a filter, which is a Write operation that creates or modifies filtering rules. While the description is empty (lowering confidence), the name and server context (FortiManager security configuration) strongly suggest this modifies security policies.

From the tool's definition Tool name 'add_url_to_filter' indicates creation/modification of URL filtering rules in FortiManager security configuration.
