create_habit · Tick MCP: Risk & Policy

WHAT IT DOES

What create_habit does on Tick

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

WHY IT NEEDS A POLICY

Why create_habit needs a policy

Creating a habit is a reversible data modification operation (habits can be deleted or updated). It does not execute code, delete data irreversibly, or move money. The medium severity reflects that habit creation affects user data and workflow state, but the impact is localized and reversible. Confidence is 0.75 due to the empty description, but the tool name and server context provide sufficient clarity.

From the tool's definition Tool name 'create_habit' indicates creation of a new habit record. The verb 'create' is a Write operation.
