## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "set_pcb_layer_visibility",
    "arguments": {}
  }
}
```

## Why set_pcb_layer_visibility is rated Medium

This tool modifies PCB design layer visibility settings, which is a reversible change to project state (layers can be toggled back). It does not execute arbitrary code, delete data, or move money. Classification as Write is appropriate. Severity is medium because misuse could obscure important design layers, potentially leading to design errors, but the change is easily reversible.

From the tool's own definition: "Tool name 'set_pcb_layer_visibility' indicates modification of PCB layer visibility settings. The verb 'set' combined with 'visibility' suggests state change to a PCB design project."

## Use case

AI agents use set_pcb_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.
