list_device_groups
AI agents call list_device_groups to retrieve information from FortiManager MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The 'list' prefix is a strong indicator of a read-only query operation. The tool retrieves existing device group data from FortiManager without creating, modifying, deleting, or executing any actions. Despite the empty description, the naming convention and context within a policy management system clearly indicate this is an informational query.
From the tool's definition Tool name 'list_device_groups' indicates a retrieval operation that queries and returns device group information without modifying state.
