About

Arduino MCP server for CLI setup, board detection, compile/upload, serial monitoring, and pin refs.

Use this server

Add it to your MCP client. The catalogue lists this config verbatim from its source — it does not run, download, or vouch for the server. Review the command before you run it.

If the button doesn't open Cursor, use the JSON below — Cursor accepts the same mcpServers config.
