Host a service on a stable public HTTPS URL straight from a cloud VM — start your app, run one command, get https://<box>-<port>.on.ascii.dev with managed TLS and token-gating. Raw TCP/UDP ports open on the VM's own IP address. Use to host a web app, API, demo, or webhook endpoint without DNS or certificate setup.
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
# Public URL hosting (Box) Use this to **put a running service on the public internet** from inside a Box: a web app, an API, a demo, or a long-lived endpoint. Box handles TLS, routing, and auth — no DNS, no certificates, no separate platform. ## Recipe ```bash box_id="$(box new --no-auto-stop --json | jq -r 'select(.event == "ready") | .id')" box ssh "$box_id" -- bash -s < ./deploy.sh # build + start app on 0.0.0.0:8080 box ssh "$box_id" -- "host 8080 --public --title 'my app'" box ssh "$box_id" -- "host url 8080" # https://<box>-8080.on.ascii.dev ``` `host` URLs are token-gated by default; `--public` makes them open. For a non-HTTP service, open a raw TCP/UDP port on the VM's IP address (IPv6 only on boxes without their own IPv4; the IP changes at each resume). Custom domains are not supported: put your own reverse proxy or CDN in front of the HTTPS URL. ## Why Box - **Zero infra** — TLS + subdomain + auth managed for you. - **Stays up** — `--no-auto-stop` (paid plan) keeps the host alive 24-7; the URL persists across resume. …

How to install
mdr add ariana-dot-dev/cloud-sandbox-vm-skills/public-url-hosting@sha256:97c1b5e3afe454c1The 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.
