WHAT IT DOES

What ticktick_merge_tags does on TickTick MCP Server

AI agents use ticktick_merge_tags 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_merge_tags needs a policy

Merging tags is a Write operation as it modifies the tag structure and organization within TickTick. While the action consolidates two tags into one (potentially destructive semantically), tag merges are typically reversible through undo functionality or by re-separating tags, distinguishing it from truly destructive operations like deletion.

From the tool's definition Tool performs 'Merge one tag into another' - this modifies existing tags by consolidating them, which is a reversible data modification operation.
