Ask the user to open that URL and choose **Approve this action** or +**Reject**. Then repeat the same tool and arguments with the token in +`confirmation`. The server refuses execution before approval, changed arguments, +expired tokens and reuse. A file approval binds the content hash as well as the +path. Approvals last five minutes and disappear when the HTTP server restarts. +A failed execution also consumes the approval; review a fresh request to retry. +The panel does not execute an action merely because it was approved. + +MCP has no approval tool. This is protection against accidental model tool +calls, not a sandbox against a client with independent shell/HTTP access to your +computer. Grant the MCP client only the access you intend. Status, captures and computer-state observations +are returned directly to that client, which may forward them to its configured +model. The assistant's separate opt-in does not govern an external MCP client. + +Power still requires the existing password prompt in a local terminal. MCP +never receives passwords.

HTTP is allowed only on loopback; other endpoints require HTTPS. +Loopback refers to the computer running the HTTP server, even in the headset. +Endpoints with embedded credentials, query strings or redirects are refused. + +Check the message consent box and press **Send message**. Screenshot context is +a separate unchecked box and sends one fresh capture with that request. Both +boxes reset after sending, and changing endpoint/model revokes consent. Nothing +is sent when opening the page or entering configuration. There is no model +list fetch, saved history, automatic screenshot capture or assistant telemetry. +Each send is independent: previous messages and replies are not included. + +Configuration, credentials and chat remain in page memory; close/reload the page +or choose **Clear everything** to clear them. A request already sent cannot be +recalled. Only the chosen endpoint gets the request; proxy environment variables +and redirects are disabled.

Remote file bytes matched; +reusing the confirmation was rejected. The actual headset Chromium page sent +text and then separately opted-in image context to a local test endpoint and +displayed its replies. Without consent there were zero endpoint requests. +The test endpoint returned canned replies: model inference and a live external +provider remain **unverified**. The launcher’s Ctrl-C cleanup was checked; +profiles, SSH tunnels and the test file were removed. No installs, removals, +launches of user games, power operations or keep-awake changes were performed. + +**Verified locally:** unit coverage includes the stdio subprocess, approval +binding/expiry/replay/concurrency, file-change rejection, and a real local HTTP +endpoint for opt-in, text/image payloads and redirect refusal. Fake-Frame +regressions are in `tests/e2e/test_agents.py`; local Docker execution was blocked +because the Docker daemon was unavailable. The ARM64 fake-Frame CI job passed +on this branch (run 36421345682). + +**Verified on the same Frame/build:** both Ctrl-C and SIGTERM close the dedicated +browser profile and SSH tunnel and remove the profile and panel log. + +![Assistant in Frame Chromium, after an opted-in request to the local test endpoint](img/assistant-panel.png) + +## Computer-use coverage + +MCP is the tool transport, not a limit on what an agent can do.

Keep explicit human handoffs. | + +## Reusing the existing computer-use work + +**Documented:** the installed `cua-driver` skill has the right control pattern: +observe an exact window, use a semantic target if available, fall back to pixels +from that same snapshot, then read back the result. Its browser route requires +an exact process/window/target binding and session-scoped element references. +Those are useful design rules for Frame tools. + +**Verified locally 2026-09-29:** `cua-driver describe get_window_state` describes +host-local process/window IDs and macOS AX inspection. It does not establish an +SSH Frame target. The installed skill's advertised Linux companion file is +missing. A native ARM64 Frame backend, its dependencies and remote transport +have not been verified. We therefore do not claim that the existing Mac driver +can control the Frame by passing it a Frame PID or screenshot, and we do not +make the feature depend on installing that application. + +Frame Control's `computer_state` is our own Python implementation over installed +platform libraries. It sends the probe over SSH stdin, writes no helper to disk, +and exits after one observation. Missing displays/libraries return explicit +errors; a 15-second process deadline prevents a stalled accessibility call from +leaving a probe behind. Window names and accessibility text are untrusted app +content, never instructions to an agent. + +**Recommended next implementation:** an isolated Chromium session with typed +snapshot/click/type/scroll tools and exact fresh target binding, then individually +verified native app actions. Use the headset capture to judge appearance, not to +invent a screen-to-window coordinate transform. Direct tool calls must retain +approval rules; a generic computer-use tool must not become a route around the +MCP approval panel, install confirmation or power confirmation. + +## Isolated browser input proof + +**Verified 2026-09-29, SteamOS 0.4.1, BUILD_ID 20260925.6191901:** a temporary +Frame Chromium profile loaded a local test page through an SSH reverse tunnel. +CDP `Input.insertText` entered the test string in its own input.

Through the wrappers, `claude auth status` reports `loggedIn: true` (`oauth_token`), and both CLIs answered a prompt with `kimi-k3`. `gamescopectl screenshot` captured another layer (the Lepton T3 app) rather than this panel. `DISPLAY=:0 xwd -id ` piped to `ffmpeg` captures the window itself (1920×1080). **Verified 2026-09-26**, BUILD_ID 20260922.6101926. | Running T3 Code as a host on the Frame | | Power actions need `sudo`, which asks for the Developer Mode password over SSH. | Frame Control's power buttons | | **SSH server:** OpenSSH 9.7p1. It offers `publickey,password` (keyboard-interactive is off, PAM on) and also asks `userdbctl ssh-authorized-keys` for keys. OpenSSH ≥ 8.8 rejects SHA-1 `ssh-rsa` signatures by default, so a client whose RSA support is SHA-1 only (the Swift library Citadel, for one) can't log in with the RSA key that devkit pairing installs; use ed25519 (**inferred** from OpenSSH defaults). **Verified 2026-09-27**, BUILD_ID 20260922.6101926. | [iphone.md](iphone.md), `ui/frame_connect.py` | +| **A Chromium app window on gamescope's `:0` with its own `STEAM_GAME` becomes a panel, even when started over SSH.** `chromium-xr/chrome --ozone-platform=x11 --app=URL --window-size=1280,720` got a 1920×1080 window, and tagging it produced `[Overlays] Created: valve.steam.desktopgame.` in `~/.local/share/Steam/logs/vrwebhelper_systemui.txt`. Chromium XR decoded a 1080p H.264 WebCodecs stream from the Mac at about 60 fps. XTest events sent to `:0` (libXtst through Python ctypes) did not reach the page.

An idle page's `requestAnimationFrame` runs at about 140 Hz; when the headset is worn or woken, SteamVR picks the 4320×2160 @ 144 Hz mode. **An unworn headset throttles panel apps** whatever they draw: a local canvas page ran at 58 fps for about 6 s, then 28, then about 15 once in standby (vrserver logs `entering standby`, with `power.pauseCompositorOnStandby 1`). `vrcmd --handlewakeup` gave 137–144 fps for about 2 s, then 36. So a panel's frame rate and compositor delay can only be measured while it's worn. `tailscaled` runs with `--tun=userspace-networking` and cost about 8% of a core at 9 Mbit/s (0.5% over the LAN address).

SSH work doesn't count as activity. The timers are the client settings `system_idle_suspend_ac_sec` (3600) and `system_idle_suspend_battery_sec` (900); 0 means Never (Settings → Power → Sleep after inactivity). They can be written over DevTools the way the settings page does. logind refuses a `systemd-inhibit --mode=block` sleep lock from an SSH session (`Interactive authentication required`) but accepts one started with `systemd-run --user`. `scripts/keep-awake.sh on|off|status` does both and restores the old timers on `off`. **Verified 2026-09-28**, BUILD_ID 20260925.6191901.

The Frame's + Steam was crash-looping during this session (below). + - Mac-hosted Remote Play has a long-standing report of the stream + closing as the game loads + ([Steam forum](https://steamcommunity.com/groups/homestream/discussions/1/574921459914429988/), + **reported**). +- **The Mac desktop through Steam: untested; single windows: no.** Valve + says Remote Play shows the host's desktop when the game loses focus + ([Steam Remote Play FAQ](https://help.steampowered.com/en/faqs/view/0689-74B8-92AC-10F2), + **documented**), so a whole Mac screen may be reachable by starting a + game, then switching away from it. Nobody has tried that from a Mac + host. It would still be one screen in one panel: Remote Play has + nothing like one panel per Mac window, so Frame Control's own stream + stays the way to see separate windows. +- **Steam has a "stream desktop" call, and it pairs with a Mac + (verified 2026-09-28).** In the Remote Play device list, the Frame's + Steam UI calls `SteamClient.RemotePlay.StartDesktopStream()` + for a connected device. Called over CDP with the Mac's client ID, it made + the Mac's Steam show "Authorize Device" and ask for a 4-digit code shown + on the Frame. Once the code was entered, the Mac logged + `k_ERemoteDeviceAuthorizationSuccess`. No stream started in that attempt, + and a second attempt, now that the device is authorized, is the next + test. If it streams the Mac's desktop, that's a whole-screen option built + into Steam: one panel, Valve's encoder and transport. It still wouldn't + give each window its own panel. +- **What Steam's work did give us: the USB-C link.** Plugged into the Mac, + the Frame appears as a network port called "Steam Frame". Steam's Remote + Play discovery uses it, and so does Frame Control's stream now (see + "USB-C, when it's plugged in" below). + +Next steps, once Steam on the Frame is healthy: + +1. Call `StartDesktopStream` again now that the Frame is authorized, and + compare its latency and sharpness with Frame Control's stream of the same + screen. +2. Stream the one Mac game installed here (Fortune Mill) from the Frame's + library, over Wi-Fi and over USB-C. +3. Record whether it starts, how it's shown, and its latency. Steam's + streaming overlay shows this; our benchmark can't measure it. +4. While streaming, switch away from the game on the Mac, and see whether + the Mac's desktop appears in the headset, and whether its keyboard and + pointer work. +5. If it works, Frame Control's Games page could offer "Stream from the + Mac" for Mac-installed games. + +## How it works + +``` +Mac Frame +ScreenCaptureKit (one window or display) + → VideoToolbox H.264 (hardware, low-latency, + no B-frames) + → frame-mac-view, 127.0.0.1 ──ssh -R──→ 127.0.0.1:479xx + → Chromium app window per stream + (WebCodecs decode), on gamescope's + X display, tagged STEAM_GAME + → its own SteamVR panel + ← CGEvent (clicks, drags, wheel, keys) ←──── pointer, wheel and key events +``` + +- **The agent** is `mac/bin/frame-mac-view`, built from `mac/frame-mac-view` + (Swift, no dependencies; `build.sh`). Frame Control's server starts it on + first use and stops it on quit. + - It captures with ScreenCaptureKit, which sends frames only when something + changes, so idle windows cost nothing. + - It encodes in hardware with VideoToolbox's low-latency rate control (plain + real-time mode where that's unavailable). + - While anyone is watching, it keeps the Mac's display awake. A sleeping + display isn't drawn, so there would be nothing to capture. +- **The link** is an `ssh -R` tunnel on its own connection. It's encrypted and + works anywhere `ssh frame` works, Tailscale included, with no firewall + changes on the Mac. If the headset sleeps or the network drops, Frame + Control reopens the tunnel on the same port, and open viewers reconnect by + themselves. +- **USB-C, when it's plugged in.** Connected to the Mac by cable, the Frame + is also a USB network device: macOS lists a network port called "Steam + Frame", and the Frame's `usb0` answers in under 1 ms. Frame Control + checks for it each time it opens the tunnel and uses it when it's there, + with the Frame's usual SSH host key. Otherwise it uses the normal path. + `FRAME_MACVIEW_USB=0` turns this off. **Verified** 2026-09-28, in two + interleaved pairs of runs: + + | | USB-C | Wi-Fi (Tailscale) | + |---|---|---| + | test: content p50 / p95 | 6.9–7.3 / 8.4–8.8 ms | 9.8–10.1 / 12.1–12.3 ms | + | test: click to drawn p50 | 16.6–16.9 ms | 26.4–27.8 ms | + | scroll: content p95 | 23.0–23.5 ms | 31.4–36.9 ms | + | scroll: late frames | 3.2–3.3% | 4.7–7.0% | + + (`bench/results/2026-09-28-*-usb1.json`, `-usb2`, `-wifi1`, `-wifi2`.) +- **Access.** + - Frame Control's own key never leaves the Mac. + - Each viewer is opened with a **single-use ticket**. It's tied to one + window or display and expires after a minute. It's spent as soon as the + viewer confirms it has received its reconnect key. Until then, a retry + gets the same key, so a connection lost at that moment doesn't strand + the viewer. Stop revokes tickets that haven't been used yet. + - After that, the viewer holds a reconnect key for that one source, in + memory only. **Stop** revokes it. + - Remaining risk: a program running as `steamos` on the Frame could read a + ticket from Chromium's command line in the first second or so and use it + first. That gets it the one source being opened, not the Mac, and the + real viewer would then fail to connect. Android apps in Lepton run in + their own podman container, so they shouldn't see the Frame's process + list (inferred, not checked). +- **The viewer** is `ui/mac-view.html`, served by the agent. It opens on the + Frame as a Chromium app window, preferring Chromium XR (`~/chromium-xr`, + built with H.264) over Flathub Chromium. + - The page puts `[fcNNNNN]` in its title. The launcher finds the window by + that tag and sets `STEAM_GAME` to a stable id per source, which gives it + its own panel (see [panels.md](panels.md)). The same Mac window gets the + same panel id each time. + - It decodes with WebCodecs. If it falls behind, it skips to the next + keyframe instead of showing old frames late. + - It falls back to JPEG stills (**Compatible** quality) where H.264 isn't + available. +- **Flow control.** The agent never lets frames queue up anywhere on the + way. It skips capture frames *before* encoding, so no reference frame goes + missing, and it lowers the bitrate, then the frame rate, then the size, to + fit the link (see [Adapting to the network](#adapting-to-the-network)). +- **Input.** + - A click on a window's panel brings that Mac window to the front + (Accessibility API), then clicks at the same point. Double clicks, right + clicks, drags and the wheel work too. + - Keys typed into the panel are sent as Mac key codes. Any keys or buttons + still held down are released if the viewer loses focus or disconnects, or + when the stream stops. Characters the key + table doesn't know, such as those from other keyboard layouts, are typed + as text. + - The Mac's own keyboard and trackpad keep working as normal. Click a panel + with the laser, then type on the Mac. + +## Permissions (Mac) + +- **Screen Recording**, to see windows. Without it, the card asks for it. +- **Accessibility**, so input from the headset reaches the Mac. Without it the + stream still works, and the viewer says clicks won't go through. + +Both are granted to Frame Control. After granting, press **Refresh**, which +restarts the helper so it picks them up.
