Absolute path to CODESYS.exe — enables the 12 ide_* tools that drive a live CODESYS V3.5 instance (Windows only).), FESTO_MCP_CODESYS_PROFILE (Required when using the ide_* tools. CODESYS profile name exactly as shown in the CODESYS version selector.), FESTO_MCP_PYTHON (Optional. Python interpreter for the XSD/semantic validators and hardware tools (needs lxml).), FESTO_MCP_ENABLE_HARDWARE (Optional. Set to 1 to enable the cpx_*/edcon_* hardware commissioning tools (bench use only).), FESTO_MCP_ALLOW_OUTSIDE_WORKSPACE (Optional. Set to 1 to allow file-writing tools to write outside the workspace directory.). The author declared them in the registry entry; get the values from the project itself.
