This connects Claude to Modern Treasury's payment operations API through Membrane's connector framework. You get programmatic access to ledger accounts, payment orders, counterparties, reconciliation workflows, and treasury reporting without managing API credentials yourself. The Membrane CLI handles OAuth flows and token refresh automatically, so you can query balances or initiate payment orders without the usual auth ceremony. Best for finance automation tasks where you need Claude to read treasury data or trigger payment workflows. The skill covers Modern Treasury's core domains but leans on their proxy endpoint when you need something outside the pre-built actions. Free tier supported if you're just exploring or building lightweight integrations.
