Get all overdue tasks (incomplete tasks past their due date)
AI agents call get_overdue_tasks to retrieve information from TickTick MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and lists overdue tasks from the TickTick service without modifying, deleting, or executing any operations. It is purely informational—querying existing task data. No data is created, modified, deleted, or destroyed. The blast radius is minimal since misuse only exposes existing task information to the AI agent, with no ability to alter system state.
From the tool's definition Tool name 'get_overdue_tasks' and description 'Get all overdue tasks' indicate a retrieval operation with no side effects. The verb 'Get' and the passive information retrieval nature confirm this is a query/fetch operation.
