Free bookkeeping software, and you can connect it to Claude or ChatGPT.
Real double-entry books, every report, unlimited businesses, free. Hand your AI a bank statement and it imports, categorizes, and reconciles.
What is MCP?
It is how an AI assistant connects to an app’s data. Claude, ChatGPT, or Grok talks to your books directly: it reads what is there and makes changes, the same way you would in the app. Nothing to install. You connect once, and then talk to your AI.
Works with the AI you already have
A month-end close is now a sentence
This is the whole workflow. You talk to the agent you already use; it operates the books through MCP tools.
Your agent, any chat

What you get
Catch-up in an afternoon
Months behind? Bulk import and bulk categorize were built as the migration workhorses; one bad row never blocks the rest.
A 1099 report your CPA accepts
Tag vendors as you go (your agent does it while categorizing) and the year-end 1099 report is ready: totals per vendor, the year’s reporting threshold flagged, missing W-9s called out.
Books that tie to the bank
Reconcile any account against its statement, down to the cent. Transfer and duplicate detection keep the feed clean, and nothing posts twice.
Reports computed live
P&L, balance sheet, and trial balance derive from the postings the moment you ask, in the app or by asking your agent a question in plain language.
And a UI when you want one
The agent does the work; you get a clean monochrome interface to check it. Dashboards, drill-through reports, reconciliation, and 1099 prep. Nothing to reconcile between the AI and the UI: they read the same books.
For developers
One URL. Any MCP client. Sixty-six tools.
LedgerMCP is a hosted, streamable-HTTP MCP server. No SDK, no local subprocess, no per-company setup. Point Claude, Claude Code, ChatGPT, Grok, Cursor, or your own agent at it and the full 66-tool accounting contract is available.

Built to be trusted with money
An agent is writing to your books. The guarantees below are enforced in the database and the transport, not left to good behavior.
Always balanced
Debits must equal credits or the database rejects the entry. An agent literally cannot post books that don’t balance.
Every write, logged and reversible
Every change an agent makes lands in a running log, tied to its key. Undo any of it in one click from Settings; nothing is ever quietly edited or deleted.
Encrypted bank access
Bank tokens are sealed at rest with AES-256-GCM, over TLS 1.2+. The browser never holds a database credential; everything goes through the server.
The full picture (architecture, encryption, and policies) is on the security page.

Frequently asked
Is it safe to let an AI do my bookkeeping?
Yes. Entries must balance or the database rejects them, postings are never edited or deleted, and every agent write lands in an audit log you can reverse in one click.
What happens if the AI makes a mistake?
You undo it in one click. Corrections post as linked reversals, so your history stays intact.
What is LedgerMCP?
Double-entry bookkeeping software with a Model Context Protocol (MCP) server built in. Connect Claude or ChatGPT and your AI keeps the books.
Do I need to know accounting or how to code?
No. Hand your agent the key and ask in plain language: “import this statement and categorize it.”
Which AI assistants can keep my books?
Any MCP client: Claude (claude.ai connectors, Claude Code, Desktop), ChatGPT, Grok, Cursor, or your own agent. You paste one snippet and the agent gets the full toolset.
Is it real double-entry accounting?
Yes. Every categorization posts a balanced journal entry, enforced in the database.
What does it cost?
The software is free, no card required. Paid plans start at $9/mo for live bank feeds, priced by the number of connected accounts; Growth and Scale include the built-in AI assistant.
Do you store my bank login?
No. Bank connections go through Plaid, and access tokens are sealed at rest, never exposed to the browser. You can also skip bank feeds and use CSV or manual entry.
Can I keep books for more than one business?
Yes, unlimited businesses on one account, free, and one API key covers them all. Accountants and bookkeepers invite staff as members and give clients a review-only view.
Can I use it without an AI agent?
Yes. Log in and use the web app directly: import CSVs, categorize, reconcile, attach receipts, and export every report.
Give your agent the keys.
Start with CSV and manual entry; connect a bank when you want the feed to flow on its own.
