Ask your assistant what you spent on groceries last month, and let it answer from your actual bank accounts instead of a spreadsheet you never update. BankMCP is a small server you run yourself that connects your European banks to Claude, ChatGPT, Cursor, or any MCP client, so questions about balances and spending get real answers. Ask for a balance and it fetches the booked and available figures live; ask where the money went and it searches transactions across every connected account by merchant or invoice number; ask for the month and it totals money in and out while leaving transfers between your own accounts out of the picture. Background watches keep an eye out between conversations: get a webhook when a balance crosses a line, a large debit lands, a named payment arrives, or an expected payment has not shown up by its date. Ready-made prompts cover connecting a bank, building a budget, scanning savings, auditing subscriptions, and spotting unusual transactions. The server is deliberately boring about your data: it keeps consents, account labels, watches, and your login, fetches balances and transactions only when asked, and stores none of them. It is read-only by design, with no payment tools to abuse. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. MIT licensed.
