WHY: connect_to_device and download_to_device against a password-protected runtime pop a modal "Device User Login" dialog in the IDE. IronPython can't marshal to the WPF UI thread to dismiss it, so headless / agent-driven sessions block forever -- and even for interactive use, the dialog pops on EVERY download, which is a constant friction point. API: ScriptOnline.set_default_credentials(username, password) was added in CODESYS scripting API 3.5.3.0. Effect lasts until end of the current script execution. Source: https://content.helpme-codesys.com/en/ScriptingEngine/ScriptOnline.html Implementation: - New helper script src/scripts/register_device_credentials.py defines a register_device_credentials_if_set() function that no-ops when DEVICE_USER or DEVICE_PASSWORD is empty, gracefully skips on older SPs that lack set_default_credentials, and never raises (always falls back to the current dialog-prompting behaviour). - connect_to_device.py and download_to_device.py call the helper as the FIRST action inside their try blocks, before ensure_project_open and any login() attempt, so credentials are registered before any code path that could trigger the dialog. - server.ts adds optional deviceUser / devicePassword args to both tools' input schemas. Resolution order: args.deviceUser (per-call override) -> process.env.CODESYS_DEVICE_USER -> '' (empty, dialog pops as before) Same for devicePassword. Env-var path is the recommended config: claude mcp add -s user codesys-sp22-patch1 \ -e CODESYS_DEVICE_USER=Karstein \ -e CODESYS_DEVICE_PASSWORD=codesys123 \ -- codesys-mcp-sp21-plus --codesys-path ... --codesys-profile ... \ --mode persistent --no-auto-launch Backward compat: when both creds are empty (default for existing users), the helper short-circuits and behaviour is byte-identical to 0.5.x. No regression. Verified by smoke-testing prepareScriptWithHelpers locally with both filled and empty inputs -- function definition + callsite are both wired in either case; only set_default_credentials() is suppressed when empty. README updated for connect_to_device and download_to_device tool rows. Version bumped 0.5.0 -> 0.6.0.
