Your agent keeps the books.

A bookkeeping and invoicing ledger for the AI you already use, like Claude, ChatGPT or Grok. Your agent files your transactions by rules you approve, matches deposits to the invoices they pay, and closes the month. The ledger holds anything that sends, deletes or exports until you say yes.

Only your email. One note when it's ready, nothing else.

your AI, connected to Agent Booksexample chat

Example chat: you ask what is new, your agent files most transactions by rule, matches a payout to its invoice, and asks you about a new rule and an unclear charge.

Just talk to it. No terminal.

Agent Books speaks MCP, the open standard that Claude Desktop, ChatGPT and Grok can connect to. When it opens, you'll add it as a connector in the app you already use, then ask for what you need in plain English. If you prefer a command-line agent, that works too.

Connector support depends on each app and plan.

What your agent can do

These are the tools the ledger gives your agent over MCP. They're built and tested, and they've kept one real business's books since October 2026. A direct daily bank feed is in testing; until then, statements come in as CSV.

  • list_uncategorizedSee what came in that no rule covers yet
  • bulk_categorizeFile many transactions in one pass
  • create_category_rulePropose a rule so it never asks twice
  • link_paymentMatch a deposit to the invoice it pays
  • create_invoice_draftDraft invoices with a PDF and a payment link
  • send_invoiceSend it, once you've approved
  • get_reportProfit and loss, spending, income by client, aging
  • export_for_accountantA year-end file mapped to Schedule C lines

Your agent proposes. You approve.

Agent Books doesn't run an agent of its own; you bring yours. It can draft, file and match freely. When it wants to send, delete, void, mark paid or export, the ledger stops at a preview and waits for you, whichever agent is asking.

No agent? It still works.

Everything your agent does, you can do yourself in the web app: categorize, set rules, match payments and run reports. There will also be a free plan for basic invoicing, covering clients, invoices with a PDF, and online payment.

Why it exists

I'm a freelance developer. I wanted my agent to run my books, not just answer questions about them, so I built the ledger it needed. It has kept my own business's books since October 2026.
