What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

    execFile(file, args, { ...options, encoding: "utf8" }, (error, stdout, stderr) => {

const SSH_KEY_PATH = process.env.FC_SSH_KEY_PATH ?? "/root/.ssh/id_ed25519";

This one needs environment variables set before it will start: ARCAGENT_API_KEY (ArcAgent API key used to authenticate MCP tool calls). The author declared them in the registry entry; get the values from the project itself.
