Zovo Group Expenses MCP
A shared expense tracker for trips or houses that allows group members to log payments, split costs equally or by shares, view balances, and generate a settle-up list. It supports multiple currencies with whole-cent arithmetic and provides a private organizer page with CSV export capabilities.

create_expense_ledger — Create a shared expense ledger page
Use this when a group wants to track shared costs for a trip, a shared house or an event and split them fairly: it publishes a shared web page where everyone adds what they paid, and returns a public link to share and a private organizer link. Optional starting expenses and payments can be included. Amounts use whole minor units of one currency (no conversion). Members are first names, 2 to 30. Does not move money, convert currencies or send reminders. Do not use for a one-off bill split that nobody else needs to see.
