WHAT IT DOES

What ticktick_complete_task does on TickTick MCP Server

AI agents use ticktick_complete_task to create or update resources in TickTick MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your TickTick MCP Server environment.

WHY IT NEEDS A POLICY

Why ticktick_complete_task needs a policy

This tool changes task state from incomplete to complete, which is a data modification. However, it is reversible (a task can be marked incomplete again), so it does not qualify as Destructive. It does not execute code or trigger external operations with variable side effects (Execute), nor does it involve financial transactions. The blast radius of misuse is limited to marking tasks as done, which a user can undo.

From the tool's definition Tool description states 'Mark a task as complete' which modifies the completion status of a task — a reversible state change. The action updates task metadata (completion flag) without destroying data or executing arbitrary code.
