AI agents call show_today_todos to retrieve information from Notion MCP Integration without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves information about today's tasks from a personal Notion todo list. It has no side effects and does not create, modify, delete, or execute operations. It is purely a data retrieval function, which places it firmly in the Read category. The severity is low because it accesses only the user's own personal task data with no capability for destructive or financial impact.
