set_task_status · Task Manager MCP: Risk & Policy

WHAT IT DOES

What set_task_status does on Task Manager MCP

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

WHY IT NEEDS A POLICY

Why set_task_status needs a policy

Changing task status is a reversible modification of data. It alters task records but does not delete them (would be Destructive) or execute external code (would be Execute).

From the tool's definition Tool description explicitly states 'Set the status of one or more tasks or subtasks' — this modifies task state. The bilingual description (English/Chinese) confirms the write operation.
