WHAT IT DOES

What load_schematic does on KiCAD-MCP-Server

AI agents call load_schematic to retrieve information from KiCAD-MCP-Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why load_schematic is rated Low

This tool retrieves and opens an existing schematic file for viewing or further inspection. It is a read-only operation that retrieves data from storage without creating side effects, modifying data, or triggering external processes. The low severity reflects that misuse would only expose design information rather than cause destructive changes or execute arbitrary code.

From the tool's definition Tool name is 'load_schematic' and description states 'Load an existing KiCAD schematic' — loading/reading an existing file with no mention of modification, deletion, or execution of external operations.

RECOMMENDED RULE

The rule that runs load_schematic safely

PolicyLayer is an MCP gateway: it sits between your AI agents and KiCAD-MCP-Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For load_schematic, this is the rule to start with:

load_schematic Allowed

load_schematic is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

{
  "version": "1",
  "default": "deny",
  "tools": {
    "load_schematic": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect KiCAD-MCP-Server, apply this rule, and every load_schematic call is checked against it from then on.
