Computer Use (Intel) 1.3.0 makes screenshot-driven actions easier to ground and verify on Intel Macs. Screenshots now include exact pixel-to-screen geometry, including cropped and downscaled images. The new get_desktop_state tool combines an image with compact Accessibility context; act_and_observe performs one action, observes the result, and optionally checks an explicit Accessibility postcondition.
Screenshot references expire and are invalidated after this server's input. App identity and display-layout checks reject mismatched references. Desktop calls within one server process run serially, and failed observations never automatically replay input. Ordinary clicks and literal Unicode typing use the native HID helper; text input leaves the clipboard unchanged. Existing raw tools remain available, for a total of 54 tools.
This model-independent MCP server works with the selected Codex model, including GPT-6 Astra. It does not change model or reasoning settings. The bundled Intel helpers target macOS 12 and later; this release was runtime-tested on an Intel Mac running macOS 26.5 with one display.
Validation: TypeScript and native helper builds, 20 automated tests without skips, independent review, plugin/skill validation, and three successful final native fixture runs. The final live run used the installed copy and checked a downscaled cropped-image click, postconditions, stale-reference rejection, an already-satisfied condition, a deliberate timeout, and exact Unicode text including umlauts and emoji.
The included ZIP contains the installer, source, Intel prebuilts, tests, and marketplace plugin files. See the README for installation and usage. Existing sessions may need a fresh MCP connection to expose the new tools.
Known limits: arbitrary external UI changes still require fresh observation; serialization is per server process. An observed result without an explicit postcondition does not establish that the intended application outcome succeeded. macOS 12 runtime behavior and multiple-display operation were not live-tested for this release.
