Marin polls a table you choose and writes organisation attributes under sync:<id>. Rows match on external_id or Marin's org id. Paste a read-only DSN, or Connect with Supabase once to mint a SELECT-only role. The default is a session-mode pooler DSN (port 5432); choose HTTPS Data API when the network only allows 443. Marin then drops the admin token; polling never uses Composio. The tenant header is not authentication — paste the admin token before a credential is stored.
