GnuCash MCP server

This is a helper that connects your AI assistant to your own GnuCash bookkeeping file. You can ask questions like how your month is going, or tell it to record a transaction, and it works on your real book. It is handy for people who keep their money records in GnuCash and want to talk to them instead of clicking around.

What this MCP server does

You ask your AI a question, like what you spent on groceries last month. The AI passes that request to this helper program. The helper opens your local GnuCash file, reads the numbers it needs, and sends them back. Your AI then explains the answer in plain words in the chat. If you ask it to add or change something, the helper writes that into the same file, just like GnuCash itself would.

What it gives back to you

You get answers in plain words in the chat: summaries, lists of accounts or transactions, totals, and warnings about things like overdue invoices or stale prices. When it changes something, it tells you what it changed. Everything stays in your local file, and the helper keeps its own audit log and backups next to it.
