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.

- 02reconexisting service and config (do not overwrite frpc.toml)

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.
- 01verifyThe frp server is reachableVerified by
timeout 5 bash -c '</dev/tcp/${server_addr}/${server_port}' && echo ok - 02verifyInstall frpcVerified by
frpc --version - 03verifyCreate the frp system userVerified by

Guardrails
Non-negotiable instructions the run must respect, whatever it finds on the server.
The frp token is a secret: do not display it, do not cat frpc.toml. Only expose the requested port, over TCP to 127.0.0.1. Do not overwrite an existing frpc.toml without a backup. frpc never runs as root.

Variables
What you choose before launching — the recipe fills in the rest.

| ${server_port} | frp server port |
| ${token} | frps authentication token |
| ${local_port} | Local port to expose |
| ${remote_port} | Remote port on the frp server |
| ${proxy_name} | Tunnel name |

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

Deploy on Servor button
Maintain frp tunnel or a project that needs it? Put this button in your README or on your site: one click and your users install it on their own server.
