create_plan · Todos MCP: Risk & Policy

WHAT IT DOES

What create_plan does on Todos

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

WHY IT NEEDS A POLICY

Why create_plan needs a policy

This tool creates new planning data (plans, sprints, or milestones) in a task management system. Creation is a write operation that modifies system state reversibly - plans can be deleted or modified later. The severity is medium because miscreated plans could affect project organization and team coordination, but the impact is limited in scope and reversible.

From the tool's definition Tool description states 'Create a new plan (sprint/milestone)' - the verb 'create' indicates data creation, a reversible write operation.
