set_dependency · Projectlibre MCP: Risk & Policy

WHAT IT DOES

What set_dependency does on Projectlibre

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

WHY IT NEEDS A POLICY

Why set_dependency needs a policy

Creating task dependencies is a reversible modification that changes project structure. This is Write category (not Destructive, since dependencies can be removed/modified), with medium severity because incorrect dependencies could disrupt project scheduling and planning, but effects are correctable without data loss.

From the tool's definition Tool creates a dependency between tasks ("Crea una dependencia entre tareas"), modifying task relationships in a ProjectLibre project file.
