kicad.create_board_outline · Eda MCP: Risk & Policy

WHAT IT DOES

What kicad.create_board_outline does on Eda

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

WHY IT NEEDS A POLICY

Why kicad.create_board_outline needs a policy

Creating a board outline is a reversible design modification that establishes the physical boundary of a PCB layout. This is Write-category because it creates/modifies design data without permanent deletion and is not executing arbitrary code or commands. Severity is medium because incorrect outlines could impact manufacturing, but the operation itself is undoable/editable in KiCad.

From the tool's definition Tool name 'create_board_outline' indicates creation of PCB board boundary geometry; sibling tools (add_component, add_wire, add_line) are all Write operations that create design elements. Description is empty, reducing confidence slightly.
