Frequently asked questions
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.
How do I add an MCP server to Claude Code?
Run claude mcp add --transport http "" in your terminal. Claude Code registers the server and discovers all tools immediately.
Can Claude Code run MCP tools in headless mode?
Yes. Claude Code supports non-interactive execution, making it ideal for scripts, cron jobs, and CI/CD pipelines that need MCP tool access.
How do I list all connected MCP servers?
