You may want to take a look at kicad-skip. It may allow you to extend your MCP to handle schematic operations.
Also, @Jean_Pierre has a post where he demonstrates using DeepSeek to design a schematic and PCB for an IOT device. It looks like he asks DeepSeek for design advice and then he manually creates the schematic and PCB using that advice. He might be able to more fully automate his design flow using your MCP server.
