ChatGPT + LedgerMCP
Connect ChatGPT to real accounting software
Most guides on ChatGPT bookkeeping end with copy-paste. Connect it to LedgerMCP instead: a real double-entry ledger ChatGPT can operate directly. It imports, categorizes, and reconciles; you review.
Connect ChatGPT in four steps
- Enable developer mode. In ChatGPT, open Settings, then Apps & Connectors, and enable developer mode if it is not already on.
- Add the connector. Create a new connector with the URL https://ledgermcp.com/mcp. ChatGPT registers itself over OAuth.
- Sign in. ChatGPT opens a LedgerMCP sign-in. Enter your email and the 6-digit code. New accounts are free and created instantly.
- Hand over the books. Ask ChatGPT to set up your chart of accounts, then give it a bank statement to import and categorize.
What changes once it is connected
Without a connection, ChatGPT can explain bookkeeping but not do it; every number moves by hand. Connected to LedgerMCP, it works like staff. Paste a statement and it imports the rows. Ask for last quarter's software spend and it queries the ledger. Tell it to reconcile checking and it walks the worksheet. The web app stays your review surface; every action lands in the audit log.
Guardrails, because it is your money
The safety lives in the database. Every entry must balance to the cent. Postings never change; corrections are linked reversals. Duplicate requests return the original entry instead of posting twice. Anything ChatGPT posts, you can reverse with one click. Destructive actions like deleting transactions stay human-only.
Common questions
Can ChatGPT connect to accounting software?
Yes. Most advice online still says it cannot, but that changed with connectors. LedgerMCP is accounting software with a built-in MCP server; ChatGPT connects to it directly and gets 50 bookkeeping tools.
Can ChatGPT do bookkeeping without copy-pasting?
Once connected, yes. ChatGPT posts entries, categorizes transactions, reconciles accounts, and pulls reports through the connection. No copying numbers between windows.
Is it safe to give ChatGPT my books?
The ledger protects itself. Entries must balance or the database rejects them; postings are immutable; every ChatGPT action is logged and reversible with one click. You can also issue a read-only key so it can report but never write.
What does ChatGPT actually see?
The books you connect: transactions, accounts, and reports. Bank credentials never pass through ChatGPT or LedgerMCP; live feeds run through Plaid with tokens encrypted at rest.
How much does it cost?
The software is free, including the ChatGPT connection, unlimited books, and all reports. Live bank feeds are the one paid feature, from $9 per month.
