SEC.01
The playbook
The run starts read-only: the recon probes decide what happens next. The steps that follow are adapted to the distribution and state found — a real machine is rarely clean.
- 01recondoes a service with the same name exist (where, active?) — if so, do not overwrite it without backup and consent
- 02recondoes the user exist? (otherwise create it as a system account)
- 03recondoes the command binary exist and is it executable? (ExecStart requires an absolute path)
- 04actCreate the ${user} user (only if missing)verify
- 05actWrite the unitverify
- 06actEnable and startverify
SEC.02
What it verifies
Each step ships its own check. The run only moves on when the check passes, so what the recipe reports as done is what is actually on the server.
- 01verifyCreate the ${user} user (only if missing)Verified by
id ${user} - 02verifyWrite the unitVerified by
systemd-analyze verify /etc/systemd/system/${name}.service && echo ok - 03verifyEnable and startVerified by
systemctl is-active ${name} && systemctl is-enabled ${name}
SEC.03
Guardrails
Non-negotiable instructions the run must respect, whatever it finds on the server.
Never overwrite an existing service without backup and explicit consent. Avoid User=root unless necessary. If the service does not stay active, show journalctl -u <name> -n 30 instead of restarting it in a loop.

How a recipe runs in Servor
Servor is zero-knowledge: the platform cannot execute anything on its own. When you launch this recipe, a run reads the reconnaissance, plans the steps and asks for your approval. Each approved command is signed by your browser — with a key the server never sees — then relayed verbatim to the agent, which verifies the signature locally before executing.
search by intent — type “firewall”, get ufw
- 01Read-only reconnaissance before any change
- 02Every command signed by your browser, approved by you
- 03Each step verified before the run moves on, every run kept in the history
