Arduino MCP Server

Wraps arduino-cli so you can check dependencies, detect boards, compile sketches, and upload firmware without leaving your MCP client. You get 20+ tools covering the full workflow: FQBN inference, core installation, serial session management with expect patterns, and even safety preflight checks before you wire up a board. It enforces an optional sketch root to sandbox file access and ships with prompts to bootstrap missing CLI dependencies or guide hardware setup. Reach for this when you're prototyping Arduino projects and want Claude to handle the compile-upload-monitor loop while you focus on the code and wiring.
