## Why pcb_set_layer_visibility is rated Medium

This tool modifies PCB design state (layer visibility) reversibly; the change can be undone or reverted. It does not delete data (so not Destructive), does not execute arbitrary code (Execute), and does not move money (Financial).

From the tool's own definition: "Tool name is 'pcb_set_layer_visibility' which modifies PCB layer visibility settings in Altium Designer. The 'set_' prefix indicates a state-changing operation. Description is empty, reducing confidence slightly."

## Use case

AI agents use pcb_set_layer_visibility to create or update resources in Altium-MCP-Suite, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Altium-MCP-Suite environment.
