lgx-mcp lets an AI agent propose online rung edits in Studio 5000
With a licensed copy of Logix Designer and its SDK, an agent can propose an online rung edit while you watch. By default it only proposes, and you decide when to test and assemble. The project says this is verified on FactoryTalk Logix Echo, not on a physical controller.
For controls engineers: have an agent propose a rung edit in Studio 5000, then test and assemble it yourself.
