At our Developer Days in Vienna, someone asked:

👉 “When will we get a command-line tool for WinCC OA?”

The discussion was around MCP Servers, AI, and how well LLMs can work with command-line tools. Building a CLI for WinCC OA had already been on my mind for quite some time. But hearing it directly from a customer pushed me to finally start.

As a first step, I created a Rust API for WinCC OA. Partly for the Rust fans out there, and partly because, to be honest, I personally prefer Rust over C++ (Caleb Eastman).

Based on that API, I’ve now built a first version of a WinCC OA CLI tool.

What commands would you like to see in a WinCC OA CLI?
