## Description

CODESYS MCP Toolkit provides AI assistants with direct integration to CODESYS V3 automation programming environments through Python scripting. Developed by johannesPettersson80, it enables seamless project management including opening/creating projects, POU (Program Organization Unit) creation and editing, code manipulation for declaration and implementation sections, and compilation tasks. The implementation uses CODESYS's built-in scripting engine to execute operations via temporary Python scripts, handling path resolution, project state management, and robust error handling with retry logic. This toolkit is particularly valuable for automating PLC development workflows, standardizing function block libraries, and integrating CODESYS projects into CI/CD pipelines or AI-assisted programming environments.
