This one needs environment variables set before it will start: GOOGLE_CONTACTS_CLIENT_ID (Google OAuth2 client id (refresh-token flow).), GOOGLE_CONTACTS_CLIENT_SECRET (Google OAuth2 client secret (refresh-token flow). Treat it as a secret.), GOOGLE_CONTACTS_REFRESH_TOKEN (Google OAuth2 refresh token, exchanged for access tokens automatically. Treat it as a secret.), GOOGLE_CONTACTS_ACCESS_TOKEN (Static OAuth2 access token (~1h lifetime) — alternative to the refresh-token trio, mostly for testing.), GOOGLE_CONTACTS_OAUTH_PORT (Fixed port for the loopback listener of the in-chat login (127.0.0.1 + PKCE). Set it when the client runs over SSH port forwarding; otherwise a free port is picked per login.), GOOGLE_CONTACTS_API_BASE (API root override.), GOOGLE_CONTACTS_TIMEOUT_MS (Per-request timeout in milliseconds.), GOOGLE_CONTACTS_MAX_RETRIES (Retries on transient errors (429 always; 5xx/network for reads).). The author declared them in the registry entry; get the values from the project itself.
