WHAT IT DOES

What clone_schematic does on KiCAD Schematic Manipulation MCP Server

AI agents use clone_schematic to create or update resources in KiCAD Schematic Manipulation MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your KiCAD Schematic Manipulation MCP Server environment.

WHY IT NEEDS A POLICY

Why clone_schematic needs a policy

This tool creates new data (a schematic copy) without modifying or deleting the original. The copy operation is reversible—the duplicate can be deleted if needed. While it may consume disk space, this is consistent with Write category tools that create or modify data reversibly. It does not execute code, destroy data, or incur financial costs.

From the tool's definition Tool description states 'Create a copy of the current schematic', which is a reversible creation operation that duplicates existing data without destructive effects.
