KiCAD Schematic Manipulation

MCP server for creating, editing, and inspecting KiCAD schematic files from AI tools and agents.

What it does

It wraps the kicad-sch-api library and exposes schematic actions over MCP, including:

• create, load, save, clone, and back up schematics

• add and remove components, wires, labels, text, and sheets

• search KiCAD symbol libraries

• inspect components, pins, and schematic metadata

• validate schematics and run bulk component updates

Related MCP server: pcb-mcp

Install

pip install KiCAD-Schematic-Manipulation

Run

python -m mcp_kicad_sch_api

Or use the installed entrypoint:
