KiCad MCP server

This is a helper for KiCad, the free program people use to design circuit boards. It lets your AI assistant open your actual KiCad project files, make changes, and run the built-in checks, instead of you clicking through menus yourself. It is handy if you design electronics and already use an AI chat tool alongside KiCad.

What this MCP server does

You tell your AI what you want, like adding a part or checking your design. The AI picks the right action from this helper, and the helper opens your KiCad files on your computer. It reads or edits the real file, then runs KiCad's own checks when you ask. You get back a short report in the chat, and your project files are updated on disk.

What you can do with it

• Add, move, or remove components in a schematic
• Trace which pins and parts are connected to a net
• Run electrical rule checks (ERC) and design rule checks (DRC)
• Sync your schematic changes onto the circuit board layout
• Export Gerber, drill, 3D, PDF, and BOM files
• Browse symbol and footprint libraries
• Fill copper zones and route a board with Freerouting

Try asking your AI

• “Add a 100 nF decoupling cap on U1's VCC pin, then check ERC”
• “List every component on my schematic and their values”
• “Push the netlist to the board and run DRC”
• “Export Gerber files and a BOM for this project”

What it gives back to you

You get answers in the chat: lists of parts, pin positions, net connections, and check results. When it runs ERC or DRC, it reports what passed and what failed. When it exports, it writes files like Gerbers or a BOM into your output folder. When it edits, it tells you what changed in your schematic or board.

Who it's for

Electronics designers, hardware engineers, and hobbyists who use KiCad and want an AI to help with schematic and board work.
