Briefing
The hosted server runs at api.heypcb.ai/mcp behind OAuth. The local npm package proxies every tool and adds upload_kicad_project and save_export. When the agent designs the board itself, it places parts and blocks and sets the outline, design rules and copper pours. Each check_board finding names the call that fixes it in a fixWith field.
HeyPCB makes the service, and the README links a Billing section whose terms we did not read. The ESP32-S3 devkit layout HeyPCB published is not in this README, and we have not checked it.
