AI agents call get_rich_menu_list to retrieve information from LINE Bot MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

It is a straightforward read/retrieval operation with minimal risk—it only exposes configuration metadata that the account owner should already have access to. Blast radius is negligible as misuse would only leak information about the account's own rich menus.
