A self-hosted MCP server that gives an assistant a cash trader's books.
Ask it what you sold today, what is running out, and who still owes you, and it answers from the same append-only ledger the trader actually writes into. Built for the Alexa+ track of Build, Ship, Shape: Amazon Developer Hackathon.
Most of the shops in a Nigerian market run on memory and a paper book. The book is honest and the memory is not, and neither of them can answer a question while the owner's hands are full of rice. The gap is not a dashboard. It is being able to ask out loud and get a number you can stand behind.

Five tools and one resource, over MCP:
record_entry writes a sale, expense, restock, credit or repayment.
day_summary gives the day's totals and the cash that should be in the box.
summarise_day_for_speech gives the same figures, phrased to be read aloud.
low_stock lists what is running out, counted from restocks minus everything that left.
outstanding_debts lists who still owes, largest first.
ledger://entries exposes the raw book as JSON.
Money is integer kobo. No float ever touches a naira figure, so a hundred small entries do not drift.
The ledger is append-only. A mistake is corrected by writing another entry, the way a paper book works.
Goods on credit are not sales. They leave stock, they raise a debt, and they stay out of the day's takings.
A credit entry with no customer name is refused, because an unnamed debt is an unrecoverable one.
A model never phrases a number. Figures are computed here and passed through verbatim; Bedrock only warms up the sentence around them, and if it is down the deterministic line goes out unchanged.
