Account and Pro
The local check, `changes`, `fix`, `init` and the MCP servers need no account. An account adds app changes from viberaven.dev and full checks from the Studio; your coding agent can open one with `login --json`, and you approve it in your own browser.
npx -y viberaven@1.7.8 account --jsonShows whether you are signed in, your plan and what is left this month. Or ask your coding agent to "show my viberaven account".
What needs no account
check,changes,fix,prompt,init,auditandrls-test.- The local Studio, opened with
npx -y viberaven. - The hosted MCP server at
https://viberaven.dev/mcpand the local@viberaven/mcpserver.
They stay free whether or not you sign up.
Sign in from a coding agent
An agent opens the account for you; you approve it in your own browser. The agent never signs in, approves or pays for you.
- The agent runs
login --jsonin the background. It prints one JSON line to stderr, with a link and an expiry time.npx -y viberaven@1.7.8 login --json - It shows you the
actionUrl. You open it, sign in with Google and approve. The link expires after about 10 minutes. - The command then prints
"state": "authenticated"and keeps the session in a private local credential store. Nothing it prints holds a token.
{"state":"requires_approval","actionUrl":"https://viberaven.dev/...","expiresAt":"2026-11-03T13:28:43.961Z"}With --json, the command never opens a browser itself; it waits up to 10 minutes, then exits 1 if the link expired or was denied. Nothing is created or charged then. Without a terminal, open viberaven.dev/go/agent/try_it instead. The full agent flow is in auth.md.
