What export_schematic_pdf does on KiCAD-MCP-Server

Why export_schematic_pdf needs a policy

This tool creates a new PDF file from an existing schematic, which is a reversible write operation (the exported PDF can be deleted or regenerated). It does not execute arbitrary code, delete data irreversibly, or modify the schematic itself—it only exports a representation to a new file. The impact is localized to file system writes with no destructive or execution risk.

From the tool's definition Tool name 'export_schematic_pdf' and description 'Export a KiCAD schematic to PDF' indicate file generation/output creation.

How to control export_schematic_pdf

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 export_schematic_pdf:

policy.json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "export_schematic_pdf": {
      "limits": [
        {
          "counter": "export_schematic_pdf_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

export_schematic_pdf stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. 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.
