# Frame Control for AI agents
|
||||
|
||||
**Documented interface:** Frame Control's own stdlib Python MCP adapter wraps
|
||||
its loopback HTTP API. No API key, hosted service, model SDK or third-party
|
||||
helper app is needed. The assistant is our HTML/Python implementation hosted
|
||||
in the platform Chromium browser. Its optional LLM endpoint is user configuration.
|
||||
Installing other apps is an optional management action, never a prerequisite.
|
||||
|
||||
## Connect an MCP client
|
||||
|
||||
The default MCP command starts a private HTTP backend on a free loopback port,
|
||||
with a fresh local access key. It stops that backend when the MCP client closes
|
||||
stdin or sends SIGTERM. It uses its own SSH control socket, so closing it does
|
||||
not close the desktop app's connection. No manually started server is needed.
|
||||
|
||||
Add this stdio server to your MCP client (use absolute paths):
|
||||
|
||||
```json
|
||||
{
|
||||
"mcpServers": {
|
||||
"frame-control": {
|
||||
"command": "python3",
|
||||
"args": ["/absolute/path/frame-control/ui/frame_mcp.py"]
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
For Codex, the equivalent registration is:
|
||||
|
||||
```sh
|
||||
codex mcp add frame-control -- python3 /absolute/path/frame-control/ui/frame_mcp.py
|
||||
```
|
||||
|
||||
New agent sessions load the entry. An already running session may need its MCP
|
||||
connections reloaded; registration does not retroactively add tools to its
|
||||
initial tool inventory. Keep the checkout at that path while it is registered.
|
||||
Use `codex mcp remove frame-control` to remove only this registration.
|
||||
|
||||
To reuse a running server instead, pass `--url http://127.0.0.1:47810`.
|
||||
The desktop app uses a random port; use that port with `--url`, or run the
|
||||
checkout server above. If the HTTP server uses `FRAME_UI_KEY`, pass the same
|
||||
value in the MCP process environment. This is local access control, not an LLM
|
||||
API key. The adapter only accepts loopback HTTP servers, refuses redirects and
|
||||
ignores environment proxies. Stdout contains newline-delimited JSON-RPC only.
|
||||
It supports MCP initialization, ping, tool listing and tool calls; no sampling,
|
||||
resources, prompts or streaming transport.
|
||||
|
||||
| Tool | Arguments | Effect |
|
||||
|---|---|---|
|
||||
| `computer_state` | none | Read-only gamescope window IDs/focus and bounded AT-SPI tree; reports incomplete observations |
|
||||
| `status` | none | Battery, services, installed games and Flatpaks |
|
||||
| `screenshot` | `view`: `headset` (default) or `desktop` | Returns PNG image content to the MCP client |
|
||||
| `job` | `id` | Background install status; poll until `done`, inspect `error` |
|
||||
| `launch` | `appid` | Launch an installed Steam app |
|
||||
| `install` / `uninstall` | `id` | Install from Flathub / remove a user Flatpak |
|
||||
| `send_text` | `text` | Frame desktop clipboard; desktop must be open |
|
||||
| `send_file` | `path` | File on the HTTP server computer, up to 16 MiB, copied to Frame `~/Downloads` |
|
||||
| `panel` | `id` | Launch an installed Flatpak as a panel using the existing launcher |
|
||||
| `power` | `action`: `suspend`, `reboot`, `poweroff` | Open a terminal for the user to enter the sudo password |
|
||||
| `keep_awake` | `action`: `on`, `off`, `status` | Optional keep-awake script interface |
|
||||
|
||||
Only install free software with its developer's consent. There is no purchase,
|
||||
entitlement bypass or arbitrary shell tool. `install` returns a background job
|
||||
ID; it does not claim the installation has finished. APK and sideloaded title
|
||||
installs remain in the main UI for now.
|
||||
|
||||
### Approval is a separate human action
|
||||
|
||||
Every mutation first returns an `approvalUrl`, exact action and `confirmation`
|
||||
token. 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. Power via `FRAME_LOCAL=1` is unsupported: use the main
|
||||
UI. The panel launcher and keep-awake adapter require zsh on the computer.
|
||||
|
||||
[PR #16](https://github.com/saphid/frame-control/pull/16) owns
|
||||
`scripts/keep-awake.sh on|off|status`. This branch does not copy or change it.
|
||||
Until that script is present, the tool reports it unavailable. Keep-awake is
|
||||
never automatic: `on` changes the shared idle timers; explicitly approve `off`
|
||||
to restore them after work. It is not a per-agent lease; coordinate with other
|
||||
users. No changes are made to the analytics/update interfaces in
|
||||
[PR #17](https://github.com/saphid/frame-control/pull/17). Prompts, keys, model
|
||||
replies, screenshots and approval payloads are not sent to analytics.
|
||||
|
||||
## Assistant panel
|
||||
|
||||
Open **Tools → Open assistant**, or `http://127.0.0.1:47810/assistant`.
|
||||
To put the same page in the headset, with the HTTP server still running:
|
||||
|
||||
```sh
|
||||
python3 scripts/assistant-on-frame.py --port 47810
|
||||
```
|
||||
|
||||
This starts an SSH reverse forward bound to Frame loopback (port 47812 by
|
||||
default), then a dedicated Chromium profile tagged as a SteamVR panel. Keep the
|
||||
command running. Ctrl-C closes this browser profile and the tunnel; it leaves
|
||||
other Chromium windows and the existing HTTP server alone. A failed cleanup
|
||||
prints the temporary profile path so it can be removed when the Frame returns.
|
||||
Use `--frame-port` if the default is busy. Chromium must already be available as
|
||||
`org.chromium.Chromium`; the launcher never installs anything automatically.
|
||||
Place the panel with SteamVR's normal docking controls.
|
||||
|
||||
Enter your full **chat-completions endpoint**, model name and optional key.
|
||||
An OpenAI-compatible local server works without a key; no OpenAI account is
|
||||
required. 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. Its privacy and retention policy still applies.
|
||||
Replies are plain text and cannot call tools or operate the Frame. A model must
|
||||
support image inputs to accept screenshot context.
|
||||
|
||||
## Evidence and limits
|
||||
|
||||
**Verified 2026-09-28, SteamOS 0.4.1, BUILD_ID 20260925.6191901:** loopback HTTP
|
||||
status through an SSH reverse tunnel; platform Chromium created a separate
|
||||
SteamVR panel (confirmed in `GAMESCOPE_FOCUSABLE_APPS`); headset capture returned
|
||||
a PNG. These checks preceded the UI implementation. No power or global settings
|
||||
were changed.
|
||||
|
||||
**Inferred:** visual comfort and controller keyboard usability while wearing
|
||||
the headset; panel creation in gamescope alone does not establish these.
|
||||
Windows/Linux launcher support, live third-party model endpoints, installs,
|
||||
uninstalls, power and keep-awake changes are not covered by that feasibility
|
||||
check. See the PR for the final unit and end-to-end results.
|
||||
|
||||
**Verified end to end on the same Frame/build (2026-09-28):** a stdio MCP client
|
||||
initialized, read status, retrieved a headset PNG, and transferred a test file
|
||||
only after approval through the Chromium page. 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.
|
||||
|
||||
|
||||
|
||||
## Computer-use coverage
|
||||
|
||||
MCP is the tool transport, not a limit on what an agent can do. A screenshot,
|
||||
accessibility snapshot, click or keystroke can all be MCP tools when we have a
|
||||
reliable underlying implementation. See [the investigation](computer-use.md)
|
||||
for the verified boundaries. `computer_state` adds observation, not an input
|
||||
channel: it cannot click an approval button or send keyboard/mouse events.
|
||||
|
||||
**Verified 2026-09-29, SteamOS 0.4.1, BUILD_ID 20260925.6191901:** the command saved
|
||||
by `codex mcp add` launched without a prestarted server, negotiated MCP, listed
|
||||
12 tools, read live Frame status and returned X11 window state plus AT-SPI
|
||||
observations. It exited 0 at EOF. Steam's accessibility tree had inaccessible
|
||||
children, reported as `incomplete: true`; this is not a complete actionable UI.

# Computer use through Frame Control MCP
|
||||
|
||||
The MCP transport can carry semantic actions or visual computer-use actions.
|
||||
The limits are the Frame's underlying interfaces, permissions and whether an
|
||||
action can be targeted and verified. A stereoscopic headset screenshot alone
|
||||
is not a reliable coordinate system for clicking a particular app window.
|
||||
|
||||
## What exists, and the right route
|
||||
|
||||
| Surface | Evidence and route | Remaining work or boundary |
|
||||
|---|---|---|
|
||||
| Frame management | **Verified:** existing SSH/HTTP operations for status, capture and file transfer work through MCP. Typed install/launch/power tools wrap the existing API. | Extend typed operations before adding generic mouse automation. Preserve explicit approval for consequential changes. |
|
||||
| App/window observation | **Verified 2026-09-29:** `computer_state` reads gamescope X11 window/app/process triples, focused app and the installed AT-SPI library. | Bounded to 96 accessible nodes and six levels. Trees may be truncated, stale, hidden or incomplete. Snapshot paths and XIDs are observations, never durable action permissions. |
|
||||
| Chromium page content | **Verified previously:** the assistant rendered and could be exercised through CDP in an isolated Frame Chromium profile. | A shipped click/type surface needs exact owned browser/target binding, fresh element references, lifecycle cleanup, consent and post-action readback. Do not expose unrestricted JavaScript or attach to arbitrary existing profiles automatically. |
|
||||
| Steam UI | **Verified 2026-09-29:** the AT-SPI service listed the Steam client's Chromium process and frame nodes, but child traversal was incomplete. Existing `frame_steam.py` uses Steam's loopback CDP endpoint for specific operations. | Prefer those narrow Steam interfaces. Presence of AT-SPI does not prove controls are actionable, and generic pointer injection is not proved for VR menus. |
|
||||
| Other Linux apps | **Verified 2026-09-29:** Frame ships libX11, libXtst and libatspi; `/dev/uinput` is writable by the current user. | Library presence and access permissions do not prove that a game accepts input. Global virtual input can affect whichever app has focus. Do not ship a blind keyboard/mouse tool on this evidence alone. |
|
||||
| Panel focus and layouts | **Documented in [#41](https://github.com/saphid/frame-control/pull/41):** `POST /api/panels` accepts `list`, `focus` and `open`. Focus was verified there. | Reuse that owned interface after integration. Its tested gamescope-owned overlay transform setters return `PermissionDenied`; no reliable saved spatial-layout interface was established. Do not duplicate its implementation here. |
|
||||
| Shared keyboard/trackpad | **Documented in [#19](https://github.com/saphid/frame-control/pull/19):** `/api/input` supplies state/start and event submission, implemented with a bundled KDE Connect daemon. | This branch does not import, launch or depend on that daemon. The user's own-implementation rule remains authoritative. A first-party input implementation or permitted bundled-library route needs its own delivery evidence before MCP integration. |
|
||||
| Physical/device boundaries | **Documented:** an asleep Frame may be off the network; power authorization can require the user's password; physical pairing and headset fit/comfort require the user. | MCP cannot bypass offline hardware, consent, compositor permissions or physical verification. 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. A CDP
|
||||
`Input.dispatchMouseEvent` press/release on its own button copied that string
|
||||
to the page's result; DOM readback matched exactly. The browser profile,
|
||||
loopback forwards and panel log were removed afterward. No user app was typed
|
||||
into, no global settings were changed and no third-party helper app was used.
|
||||
|
||||
AT-SPI did **not** expose the test page's controls in that same probe, even with
|
||||
Chromium's renderer-accessibility flag. It returned the partial Steam-client
|
||||
tree instead. The reason remains **unverified**; this is an evidence gap, not
|
||||
proof that Frame accessibility cannot work. For a first implementation,
|
||||
Chromium's proven page-specific CDP route is stronger than assuming complete
|
||||
AT-SPI coverage. This proof does not ship unrestricted click/type tools or
|
||||
establish input delivery to SteamVR's menus.
