deploy-an-app

deploy-an-app is a skill for Claude Code from imprezahost/impreza-mcp. It costs 56 tokens per session (772 once invoked), scanned A, original, MIT.

A deployment workflow for putting an application on an Impreza VPS, either from a catalog or a Git repository. It waits for the server to finish and checks whether the app actually responds.

In plain words
What is it for?
Use it to choose an available server, deploy a catalog or repository-based app, monitor deployment status, and confirm that the running app answers.
Why use it?
A deployment request starts background work and returns an ID, not a final result. This prevents reporting success while the app is still starting or has failed.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

deploy-an-app scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 15d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 75 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Deploying to an Impreza VPS

Nothing here is synchronous

This is the single thing that goes wrong most often. A deploy call returns an id, not a result. The container is still being pulled while you are reading the response. If you answer "done" at that point you are guessing, and roughly half the time you are wrong.

Every long-running family works this way: deploys, backups, scheduled task runs, app reads and CLI runs. The call starts the work; a second tool reports how it went.

So the shape of every deploy is:

  1. start it, keep the id
  2. poll impreza_list_deployments (or impreza_get_environment_deploy for an environment deploy) until the status settles
  3. only then say what happened

A deploy that has not settled is not a deploy that failed. Say it is still running.

Pick the server first

impreza_list_servers shows what the account owns and which boxes are online. An app has to land on one of those. If the account has no server yet, see the start-from-nothing skill — buying one is a separate arc with its own rules about money.

Catalog or custom

Catalog (impreza_list_apps → impreza_deploy_catalog_app) is the fast path: WordPress, Nextcloud, Gitea, n8n, Vaultwarden and the rest arrive configured, not at a setup wizard. Prefer it whenever the request names something in the catalog. Search the catalog before assuming an app is missing.

Custom (impreza_deploy_custom) takes the customer's own image, Dockerfile or git repository. Reach for it when the app is theirs.

For a Compose stack, impreza_prepare_compose first: it turns the file into something the platform can accept and tells you what it refused and why. Do not hand-translate a Compose file yourself.

After it settles

impreza_probe_deployment answers the question the status field does not: is it reachable over public HTTPS. A deployment can be running and still not serve, because DNS or the certificate is not there yet. If the customer asked for a working site, probe before you claim one.
