What extract_schematic_netlist does on KiCad MCP Server

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

Why extract_schematic_netlist needs a policy

This tool retrieves and analyzes existing schematic data to produce netlist information as output. It has no side effects on the schematic files or external systems. The operation is read-only—it observes and reports on the structure of KiCad design files without altering them or triggering any computational processes beyond parsing.

From the tool's definition Tool description states it 'parses a KiCad schematic file and extracts' netlist information. The verb 'extract' combined with 'parses' and the return of 'netlist information' indicates data retrieval with no modification.

How to control extract_schematic_netlist

PolicyLayer is an MCP gateway — it sits between your AI agents and KiCad MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for extract_schematic_netlist:

policy.json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "extract_schematic_netlist": {}
  }
}

extract_schematic_netlist is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

  1. Create a free account and register KiCad MCP Server — nothing to install.
  2. Add this policy — paste it, or build it visually.
  3. Point your MCP client (Claude, Cursor, anything) at your gateway URL.
