reflex-cu 0.3.5: computer use MCP server with Jev

reflex-cu is an open-source computer use MCP server for Claude Code, Codex and other AI agents. It controls macOS and Windows desktops, and a remote Windows machine over SSH, by reading the accessibility / UI Automation tree instead of taking a screenshot at every step. Jev, TypeSafe's System One decision model, answers the small decisions between steps.

What is in this release

• Three ways to reach Jev: a key from TypeSafe, OpenRouter or Command Code. On a network that cannot reach TypeSafe directly, an OpenRouter key works without a proxy in our tests.
• Control state, not just names (Windows and macOS): what a dropdown is set to and whether it is open, whether a switch is on, what a text field contains, which group a repeated button belongs to.
• Items scrolled out of view are listed on Windows and scrolled to automatically when clicked.
• macOS system panels such as Spotlight count as the foreground window, so waiting for them no longer times out.
• Batched steps report per-step timing and stop as soon as the judge is unsure.

Measurements

Same agent and task sentence, all tools versus the same server limited to screenshots and clicks, two runs each:

Task	All tools	Screenshots and clicks only
macOS: "open the ChatGPT app"	8 / 9 s, 4 calls	18 / 30 s, 7 / 12 calls
macOS: "open Calculator and work out 1234 times 56"	23 / 22 s	35 / 38 s
Remote Windows: five changes in Settings	61 / 88 s, about $0.27	54 / 72 s, $0.40–0.56
