mcp-kicad — MCP server exposing KiCad PCB Editor functionality via IPC API.
pip install mcp-kicadThe MCP server communicates with a running KiCad instance via the IPC API. Start KiCad first, then run the server:
mcp-kicadOr configure it in your MCP client:
{
"mcpServers": {
"mcp-kicad": {
"command": "mcp-kicad",
"env": {}
}
}
}The server exposes the following tools:
