Run a long-lived or 24-7 background worker in a cloud VM that won't auto-stop — queue workers, schedulers, bots, crawlers, or persistent agent loops. Turn auto-stop off (paid plan) or set a TTL up to 30 days; the VM keeps its disk across stops and resumes later. $0.036/h for 4 vCPU / 8 GB, about $26 a month always on, billed per second.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Background / 24-7 worker (Box) Use this when work must **keep running unattended**: a queue worker, a Telegram/Discord bot, a polling agent, a scheduled scraper, or any always-on service. Many sandboxes stop on a session timer by default (for example, E2B and Codespaces), and some offer pause or longer sessions on paid plans. A Box can run with **auto-stop off** and keeps its disk across stops. ## Why Box - **No session cap once auto-stop is off** — the default is 1 h from creation or resume; set up to 30 days, or turn it off on a paid plan. - **Persistent + resumable** — the disk survives a stop (kept at least 14 days; save a snapshot to keep it longer); `box resume` brings it back. The IP changes at each resume. - **Flat per-hour price** — one always-on 4 vCPU / 8 GB VM costs about $26/mo on Box vs about $392 on E2B ($242 usage + $150 Pro plan) and about $347 on Modal (2 Modal cores) at list price (https://docs.boat.dev/pricing, https://e2b.dev/pricing, https://modal.com/pricing). E2B Pro and Modal cap one sandbox session at 24 h; both document pause or filesystem snapshots to continue. A running Box bills at full rate, busy or idle. ## Prereqs …

How to install
mdr add ariana-dot-dev/cloud-sandbox-vm-skills/background-worker@sha256:96bd1822801070fdThe line at the top of this page pins the label git:20261109.2f1d005, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
