WHAT IT DOES

What create_mortise_tenon does on SketchupMCP

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

WHY IT NEEDS A POLICY

Why create_mortise_tenon needs a policy

This tool creates a new 3D modeling joint between components in SketchUp. It modifies the scene by adding/altering geometry, which is a reversible write operation. While it runs within SketchUp, it doesn't execute arbitrary code (unlike eval_ruby) and doesn't irreversibly destroy data.
