uncomplete_habit · Poke HabitTracker MCP: Risk & Policy

WHAT IT DOES

What uncomplete_habit does on Poke HabitTracker MCP

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

WHY IT NEEDS A POLICY

Why uncomplete_habit needs a policy

This tool creates or modifies data in a reversible manner (toggling habit completion status), fitting the Write category. Severity is medium because misuse could cause an AI agent to incorrectly mark habits incomplete, creating confusion about user progress, but the action is easily undone by re-completing the habit.

From the tool's definition Tool description states it 'Mark today's matching HabitTracker habit incomplete' — this modifies habit state by changing completion status. The qualifier 'without deleting logs' confirms it is reversible modification rather than destructive deletion.
