Couples Shared Account Engine MCP Connector for Claude

The Couples Shared Account Engine provides a precise way for partners to manage joint household expenses. By using income-based proportions, the engine ensures that each partner contributes a fair share relative to their earnings. Use calculate_income_proportions to determine the weight of each person's contribution, or calculate_individual_transactions to find exact currency amounts due for shared costs. The engine also handles complex reconciliation with calculate_reconciliation_transfer, calculating exactly how much one partner needs to transfer to another if expenses were paid upfront. Finally, use calculate_partner_surplus to evaluate financial stability by checking remaining funds after all obligations are met.
