This one needs environment variables set before it will start: GOOGLE_TAGMANAGER_CLIENT_ID (Google OAuth client id (refresh-token flow).), GOOGLE_TAGMANAGER_CLIENT_SECRET (Google OAuth client secret (refresh-token flow). Treat it as a secret.), GOOGLE_TAGMANAGER_REFRESH_TOKEN (Google OAuth refresh token; exchanged for access tokens automatically. Treat it as a secret.), GOOGLE_TAGMANAGER_ACCESS_TOKEN (Ready-made OAuth access token (~1h lifetime). Alternative to the client-id/secret/refresh-token trio.), GOOGLE_TAGMANAGER_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_TAGMANAGER_API_BASE (API root host override.), GOOGLE_TAGMANAGER_TIMEOUT_MS (Per-request timeout in milliseconds.), GOOGLE_TAGMANAGER_MAX_RETRIES (Retries on transient errors (429, quota 403, and 5xx/network for reads).), GOOGLE_TAGMANAGER_MIN_INTERVAL_MS (Minimum spacing between API requests, for the 0.25 QPS quota.). The author declared them in the registry entry; get the values from the project itself.
