Frequently asked questions about the Splitwise MCP Server

Can the agent distribute the bill unequally?

Yes! When creating an expense, the AI agent can pass detailed users configuration in JSON to specify exact dollar amounts for each involved party.

How far back does the expense log go?

The agent typically limits the reading to the 20 most recent expenses to keep memory manageable, but can be instructed to pull earlier ones.

Can the bot settle debts?

Currently, the agent interacts with expenses. To log a debt settlement, the agent submits a specific 'payment = true' expense wrapper via the splitwise schema.
