KiCAD MCP Server is a Model Context Protocol (MCP) server that enables AI assistants like Claude to interact with KiCAD for PCB design automation. Built on the MCP 2025-06-18 specification, this server provides comprehensive tool schemas and real-time project state access for intelligent PCB design workflows.

Design PCBs with natural language

Describe what you want to build — and let AI handle the EDA work. Place components, create custom symbols and footprints, route connections, run checks, and export production files, all by talking to your AI assistant.

What it can do today

• Project setup, schematic editing, component placement, routing, DRC/ERC, export
• Custom symbol and footprint generation — for modules not in the standard KiCAD library
• Personal library management — create once, reuse across projects
• JLCPCB integration — parts catalog with pricing and stock data
• Freerouting integration — automatic PCB routing via Java/Docker
• Visual feedback — snapshots and session logs for traceability
• Cross-platform — Windows, Linux, macOS

Quick Start

1. Install KiCAD 9.0+
2. Install Node.js 18+ and Python 3.11+
3. Clone and build:

git clone https://github.com/mixelpixx/KiCAD-MCP-Server.git
cd KiCAD-MCP-Server
npm install
npm run build

4. Configure your AI client — see Platform Guide
