List all antenna designs in the current session.
AI agents call nec2_list_antennas to retrieve information from Mcp Nec2 Antenna without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns a list of existing antenna designs without creating, modifying, deleting, or executing any operations. It is a pure read operation with minimal risk—the worst outcome is disclosure of antenna design metadata already within the session scope.
From the tool's definition Tool name 'nec2_list_antennas' and description 'List all antenna designs in the current session' indicate a retrieval operation with no side effects.
