ToolsEngine 0.1.9-rc.1 — native Windows qualification

ToolsEngine 0.1.9-rc.1 is a release candidate for the standalone MCP server, with Linux x64 and native Windows x64 archives. Windows runs directly under Node.js; WSL is not required. This release fixes normal downloads being cancelled when Chromium replaces an empty destination while the download watcher observes it. Link, size and observation-error protections remain enforced.

The OpenAI plugin entry has a fixed eight-tool file/public-web ceiling and refuses browser, desktop, profile transfer and private-network startup. Standalone browser and Windows desktop options remain explicit. This is self-distributed software; technical tests do not establish vendor marketplace approval or subscription eligibility.

Validation for exact source f7bfca9d8949251d08d36bfb95ef8270d78663b2:

• Linux suite: 316 tests, 286 passed, 30 skipped, zero failures/cancellations/todos. Owned browser qualification used the browser sandbox; synthetic CDP attachment fixtures have their own test-only launch settings.
• Native Windows 11 Pro x64, Node 24.20.0: 316 tests, 282 passed, 34 skipped, zero failures/cancellations/todos. The Edge long-workspace test ran and passed. Skips are not passes.
• The exact Windows archive was installed under the interactive desktop account, compared against its manifest/source, exercised through its installed entry (8/8 desktop checks; zero skips), checked again, and uninstalled successfully. See windows-qualification.json.
• Focused download regressions and two causal mutation checks passed after restoration. The independent referee found no remaining measured blocker within the reviewed scope.

Requirements: Node.js 22.14+, x64 Linux or Windows, and Windows PowerShell 5.1/local NTFS for Windows. Extract into a fresh folder, then use install.cmd --browser none on Windows or ./install.sh --browser none on Linux. Add --register claude codex to register those clients. Add --desktop only for explicitly requested standalone Windows desktop control. Provider plugin setup is documented separately in app/docs/CODEX.md.

The stable 0.1.8 release and npm publication are unchanged. This candidate does not claim real-host acceptance by every MCP client or new marketplace listing.
