Outbound internet access is enabled, the in-VM `user` account has passwordless sudo, and `/workspace` is stored with E2B. Internet access is an egress path that OpenMuse does not review: approval gating covers only the app's own email and calendar tools, so a prompt-injected agent could send data from the computer or submit forms in its browser. The live desktop stream is reachable from the internet and protected only by the VNC password in its URL (8 effective characters); treat that URL as a bearer secret. All listening VM ports are publicly reachable at `https://-.e2b.app` without application authentication; public traffic is enabled to allow the direct desktop iframe. The sandbox ID appears in the stream hostname and is not an access control. For example, `python3 -m http.server 8000` in `/workspace` exposes workspace files to the internet. Do not leave servers running or put sensitive files in an unauthenticated service. The iframe is sandboxed to block forms, popups and top-level navigation, but VM-controlled content can still display misleading prompts. The E2B API key stays on the API host and is never passed into the VM or to the client. A unique `COMPUTER_DEPLOYMENT_ID` is required, because sandboxes are matched by metadata across the whole E2B team.

Outbound internet access is enabled, commands run as root in the VM, and `/workspace` is stored on the VM's disk at BoxCompute. As with E2B, internet access is an egress path OpenMuse does not review. The desktop stream is a BoxCompute viewer link: a random hostname that serves a noVNC page and is a bearer secret giving full keyboard and mouse control until it expires or the API key is revoked. The page is embedded with the same iframe sandbox as the E2B stream. No other port in the VM is reachable from outside. The BoxCompute API key stays on the API and task worker, and is never sent into the VM or to the client. `COMPUTER_DEPLOYMENT_ID` is required because VMs are matched by metadata across the whole account.

As with E2B, the API host needs no Docker engine, and you can watch and control the desktop from the app. + +```dotenv +COMPUTER_ENABLED=true +COMPUTER_PROVIDER=boxcompute +BOXCOMPUTE_API_KEY=bc_live_... # API and task worker only; never passed into the VM +COMPUTER_DEPLOYMENT_ID=... # required and unique per install, e.g. `openssl rand -hex 12` +# BOXCOMPUTE_WORKSPACE_ID=ws_... # optional; default: a workspace named OpenMuse, created if missing +# BOXCOMPUTE_API_URL=https://api.boxcompute.ai # default +``` + +Create the key under **API keys** in the BoxCompute console. A console key has full sandbox access, which covers the provider and the live smoke test. The provider uses `sandbox:read`, `sandbox:create` and `sandbox:execute`, plus `workspace:create` unless you set `BOXCOMPUTE_WORKSPACE_ID`; the smoke test also uses `sandbox:delete` to clean up. + +Open **Computer → Start computer**. The first start creates the VM, which takes about a minute, and starts its desktop; later starts resume it. The **Desktop** tab and the chat card work as for E2B. The stream is a BoxCompute viewer link, a random hostname serving a noVNC page. Treat it as a bearer secret: anyone holding it can watch and control the desktop until it expires, an hour after the app last asked for it and at most 24 hours after it was made, or until the key is revoked. Asking again while the Desktop tab is open keeps the same link. + +How it maps to the Docker contract: + +- **One VM per owner and deployment**, found by VM metadata across your whole BoxCompute account, which is why `COMPUTER_DEPLOYMENT_ID` is required here too. The app refuses to attach to a VM whose metadata it did not set, or that is not a large, network-enabled VM (the desktop needs its 3 GiB of memory). +- **`/workspace` persists; processes do not.** Stop stops the VM: every command and desktop app ends, and its disk, `/workspace` included, is kept. BoxCompute stops a VM the same way after 30 minutes without API activity; commands, file operations and desktop actions count, and an open Desktop tab keeps it awake. The VM is created with `autoResume` off, so a command, file call or desktop action never wakes a stopped VM: only Start does. A stopped VM keeps its disk, and counts toward your account's storage, until you delete it in BoxCompute. +- **Commands** run as root in `/workspace`, with the same 30-second wrapper, exit code 124 on timeout and 128 KB output cap. The command reaches the VM in an environment variable rather than in argv, because BoxCompute limits one argument to 8 KB. File operations use BoxCompute's file API with `files.py`'s limits, symlink refusals and response shape, so no request crosses on stdin; a file above 8 MB is written in parts beside it, joined in the VM and renamed into place. +- **GUI apps from the terminal.** `chrome https://copilotkit.ai >/dev/null 2>&1 &` opens Chrome on the desktop with the image's reviewed browser sandbox. The same output handling as E2B applies, so a backgrounded app does not keep the command open. +- **Command history is per provider.** + +#### The agent drives the BoxCompute desktop + +`use_desktop` is the same tool with the same actions. Each one becomes one BoxCompute desktop call whose response also carries the PNG screenshot taken half a second after it, so an action costs one round trip. The screenshot is a PNG because BoxCompute's VM image does not capture JPEG; models are charged by image dimensions, so it costs no more tokens than E2B's JPEG. BoxCompute sends the input as a VNC viewer's keyboard and pointer events. + +- **Keys.** `key` accepts xdotool names and combos and maps them to BoxCompute's keys: Return, Tab, Escape, BackSpace, Delete, Insert, Home, End, Page_Up, Page_Down, the arrows, space, F1 to F12 and printable characters, with the modifiers ctrl, alt, shift and super. A sequence such as `ctrl+l Return` is sent as one call per combo. A key BoxCompute has no name for is refused before anything is sent. +- **Text.** The VM's keyboard is US ASCII, so `type` accepts printable ASCII, newline and tab, and refuses other text before typing any of it.
