Arduino MCP Server

Wraps arduino-cli so Claude can compile sketches, upload to boards, and monitor serial output without you touching the terminal. It handles board detection, core installation, and keeps stateful serial sessions open so you can read, write, and wait for expected patterns. The safety preflight tool runs electrical checks before sending commands to pins. You get structured board references as a resource and guided setup prompts for bootstrapping from scratch. If you're prototyping with Arduino and want to describe what you need in natural language instead of switching between IDE and chat, this bridges that gap. Requires arduino-cli on your PATH or lets the server walk you through installing it.
