Claude MCP Server
for Accounting
Fix transactions, migrate information, create reports, and much more, all within Claude. Work on one or multiple businesses at the same time.
We work with the best in the business
What is an MCP server?
Software that lets an AI assistant work inside a system holding real data.
What is a Claude connector?
How you add an MCP server to Claude: connect once from your own account, and Claude can work with it while you chat. No code, no exports.
What does the ReInvestWealth MCP server do?
It lets Claude work in your books, not just look at them: adjustments, migrations, edits, reports, projections, even the update email that goes out with them. Across one business or multiple businesses at the same time.
Is MCP only for Claude?
No, it is an open standard. We are building for Claude first because its connector support is the most mature.
How to connect your books to Claude
In the Claude app you already use, or in Claude Code.
Connect it to Claude
One connection, from your own Claude account. Nothing to install.
Ask, or tell it to go do it
Claude answers from the real ledger, or makes the change you asked for.
You approve what it does
It inherits your permissions, and asks before it changes anything.
The app stays simple. The heavy lifting lives in the MCP.
Built for both sides of the ledger
Adjustments, migrations, reports, projections, the email that goes with them. Claude does the work instead of handing you a to-do list.
If you run an accounting firm
- Close out December across all 30 files and flag anything needing my judgment.
- Which clients are trending toward a loss? Draft a heads-up email for each.
- Post these year-end adjusting entries and tie out the balance sheet.
- Match the transfers between their bank accounts and flag any one-sided ones.
- Start the GST/HST filing process for all my clients.
- Find every transaction over $10k and tell me which need support.
If you run your own business
- Backfill last year from these bank statements so my books are complete.
- Get my books ready for my accountant and email them the package.
- Review last month and fix what's wrong, with my okay first.
- Which subscriptions am I still paying for that I don't use?
- How much can I afford to pay myself this quarter?
- Prepare my GST/HST return, show me what I owe, and e-file it.

Questions about the MCP server
How do I add the ReInvestWealth MCP server to Claude?
From Claude's connector settings: point Claude at the ReInvestWealth MCP server and sign in with the account you already have. No install, no API keys. The exact steps ship with the launch email.
Can my firm use it across client files?
Yes, and it is the part we are most excited about. One instruction, every client file, at the same time. A cleanup that takes a junior a week runs in parallel across the whole book instead of one file after another. Firms go into early access first.
Claude can change my books. What stops it going wrong?
It only reaches what you reach, it asks before it changes anything, and every change is an ordinary entry you can see and edit in the app. Nothing is hidden.
When does it launch?
Soon. We are shipping it to small groups first, watching what people actually ask it, and fixing what breaks before the next group.
How is this different from a QuickBooks or Xero MCP server?
Theirs are open-source servers for developers: you run one, register an app, handle OAuth, one company file at a time. Ours is part of the platform, inherits your permissions, and works across every client file a firm can already see.
Do I need Claude Code or Claude Cowork?
Neither in particular. It is a connector, so it works with your Claude account rather than one specific app: use whichever you already work in.
Do I need a paid Claude plan?
You need a Claude account, and connecting a custom MCP server depends on your plan (Anthropic's call, not ours). The launch email spells out exactly what is required.
Look under the hood
Get your books ready for it.
The MCP server is only as good as the books behind it. Start free, let the AI keep them current, and be ready the day early access opens.
Cancel anytime. Firms: ask about MCP early access on the call.
