Credentials from the publisher

THREE_WS_API_KEY — A three.ws API key (sk_live_… / sk_test_…) or OAuth access token. Optional: needed only for knock_inbox and knock_act, which manage your own door. Quoting, browsing, knocking and reading a receipt all work without it. Treat like a password.
THREE_WS_BASE — Base URL of the three.ws API. Override only when self-hosting or targeting a preview deployment.
THREE_WS_TIMEOUT_MS — Per-request timeout in milliseconds.

Claude Code has no install link for a local command. Copy the command below and run it in a terminal.
