Free and open source (MIT); needs KiCad 10. Uses the model in your own AI app.
Overview
Copper is an open-source MCP server that connects your AI app to KiCad, the free electronics design suite. You describe a board, such as a USB-C powered ESP32 board of a given size, and the AI connects pins to nets by name, picks real in-stock LCSC/JLCPCB parts with their footprints, places and routes the PCB, and re-runs KiCad's own electrical and design-rule checks after every change. It renders the schematic, layers and 3D views so the model can look at its work, then writes Gerbers, drill, BOM and placement files for JLCPCB, PCBWay or OSH Park. It works with Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Codex and other MCP apps; Windows is tested end to end and macOS and Linux installers are new. You get a checked KiCad board and a zipped set of files ready to order.
