TOOL

Codesys-MCP-Master, 3 stars: one MCP server drives every installed CODESYS version with 132 tools

An agent can write function blocks, compile and fix errors, rename variables across a project, run a simulation and download to a PLC, picking the right CODESYS version from the project file. Whether a download or PLC write needs a person's approval is set in the AI client, not the server, so that setting is the one to get right.

For controls engineers on CODESYS-based PLCs: hand off the routine edit, compile and release chores while keeping each tool call visible.

"Describe a process in plain English. Press Build.": a Claude agent that builds and solves a process flowsheet

In AI Process Simulator the agent plans the components, fluid package and equipment, you review the specs and assumptions, and the simulator's own solver computes every result. It cannot delete equipment or rewire connections yet, and five to ten unit flowsheets cost about $0.05 to $0.12 in API usage in his testing.
