Which QuickBooks MCP server should you use?
Seven serious ways now connect QuickBooks Online to an AI assistant, and they are not equivalent. Some read two reports. Others reach the whole general ledger. Here is the honest picture, including where Caribooks is the wrong answer.
Updated 3 September 2026.
Does QuickBooks have an MCP?
Intuit ships two things, and neither one is a hosted MCP server over the whole general ledger. The open-source QuickBooks Online MCP server on GitHub runs on your own machine and needs an Intuit developer account. The QuickBooks connector built into Claude and ChatGPT installs in one click, but as of September 2026 it is limited to sales documents, a profit and loss and a cash flow statement, and it is not offered to Canadian QuickBooks companies. The hosted options that reach the whole ledger come from third parties. QuickBooks Connector by Meridian, released free by Pilot in August 2026, writes everywhere and holds several companies. Caribooks is paid and adds 35 named reports, French, Canadian books and a per-company read-only default. Around them sit general platforms: Zapier MCP for chaining QuickBooks into other apps, CData Connect AI for SQL queries, and Composio for agent developers.
The options
Intuit's official QuickBooks connector (Claude and ChatGPT)
For: the US owner who wants books connected in one click.
What it does: profit and loss, cash flow, industry benchmarking, transaction import, business profile, and the whole sales side. Invoices and estimates get created, updated, sent, duplicated and deleted, recurring invoices managed, reminders sent, payment links generated. Payroll questions and QuickBooks Capital loan benchmarks arrived in 2026.
The limit: Intuit's help article says the use cases are limited to that list, and it is not offered to Canadian QuickBooks companies (checked 21 August 2026 against a Canadian file; Intuit publishes no region list). No balance sheet, no trial balance, no aged receivables, no general ledger, no journal entries, no vendors, no bills. Free with a QuickBooks subscription.
QuickBooks Connector by Meridian
For: the bookkeeper who wants full reach, hosted, for nothing.
What it does: Pilot, the firm behind the Meridian platform, released this free hosted server on 11 August 2026. It connects several QuickBooks companies to one agent, reads reports and the transaction detail behind them, and creates or modifies journal entries, invoices, bills, payments, purchases and transfers. Each company gets its own read-only or read-write setting. Claude, Cowork, Codex and ChatGPT.
The limit: its FAQ says only one user can access a given client company, so a firm cannot share a client yet. No tool or report catalogue is published, and it is a free side release from Pilot, whose paid product runs the close itself.
Intuit's open-source MCP server (GitHub)
For: the developer at home in a terminal.
What it does: 145 tools. Full create, read, update and delete across 29 entity types, plus 11 reports including balance sheet, trial balance and general ledger. MIT licensed, free.
The limit: it runs locally over stdio. You need an Intuit developer account, an OAuth app, and a client ID, secret, refresh token and realm ID in a .env file. Intuit's portal rejects localhost redirects in production, so the first authorization needs a public HTTPS callback. One company per install, and nothing local reaches Claude on the web or a phone.
Zapier MCP
For: someone chaining QuickBooks into other apps.
What it does: you pick which actions to expose (create a bill, a deposit, a credit memo, a customer) and get an endpoint that also reaches 9,000 other apps. Setup is guided, no terminal.
The limit: it does actions, not reports. The QuickBooks list is records to create, with no financial statement in it. Every tool call spends two tasks from your Zapier quota, and the free plan holds 100 a month, so 50 calls.
CData Connect AI
For: a data team already living in JDBC drivers.
What it does: exposes QuickBooks as a live, SQL-queryable source behind one MCP endpoint, with query logging, per-user permissions and SOC 2. Reads and writes run through a fixed set of operations: query, insert, update, delete, join, aggregate, bulk.
The limit: this is data-team tooling. There are no canned accounting reports, you write queries. Plans are annual after a 14-day trial, and the governance that justifies the price is aimed at an IT department.
Composio
For: someone building an agent, not keeping books.
What it does: a developer platform whose QuickBooks toolkit covers the ledger, with balance sheet, profit and loss, cash flow, trial balance and general ledger reports, plus create, update and delete. Its router loads only the tools a task needs. Free up to 100,000 tool calls a month.
The limit: you are configuring an agent platform, not opening your books. It expects an API key, a framework and code around it. Heavy if you wanted to know who owes you money.
Caribooks
For: the owner, accountant or bookkeeper who wants the developer server's reach without being one.
What it does: 221 tools, 35 reports, the whole ledger in both directions, hosted. Authorize QuickBooks once and it is connected, including Claude on the web and on a phone. Several companies under one subscription, Canadian and US books, French or English.
The limit: the free tier stops at one company and 50 reads a month, about forty questions. Past that it is $99 a month for five companies with no quota, and Autopilot is priced per company. Meridian's connector is free with no ceiling and reaches the same API, so the question is whether 35 named reports, read-only by default, French and Canadian books are worth the line item. If your whole need is a profit and loss, they are not.

A hosted server is added to your Claude account, so it follows you to the web, the desktop app and the phone. A local server exists only where its process runs.
Set it up in Claude
Four paths, shortest first.
Caribooks
Sign in at caribooks.com with an emailed link, authorize QuickBooks once, then press Add to Claude in the portal. Approve the consent screen and the tools appear. Every connection starts read-only; you switch a company to full access in the portal.
Intuit's official connector
In Claude, open Connectors in the left navigation, find QuickBooks, select Connect, and sign in to Intuit.
Connector by Meridian
Sign in with Intuit on the connector's site, pick the companies and their access level, then add the server to your agent. Pilot says under three minutes.
Intuit's open-source server
Clone the repository, register an app on the Intuit Developer Portal, put the client ID, secret, refresh token and realm ID in a .env file, build, then point your MCP client at the built file.
When not to pick Caribooks
Four cases where we are honestly the wrong tool:
- You want the reach without paying and you work alone. Meridian's connector is free, hosted, and writes everywhere.
- You only want a profit and loss and to send invoices, and your books are in the US. Intuit's own connector does that in one click, at no extra cost.
- You are a developer and a local process does not bother you. Intuit's open-source server is free and covers most of the ledger.
- You are on QuickBooks Desktop. Nothing above works: Desktop has no API.
How to choose
You just want to talk to your books with nothing to install
If you are in the US, start with Intuit's official connector. The day you need a balance sheet, an aged receivables report or a journal entry, you will know exactly why you are moving on.
You keep books for several companies
The open-source server needs one install per company. Meridian and Caribooks both hold several. Meridian's FAQ notes only one user per client company.
Your books are in Canada
Intuit's connector is not offered to Canadian QuickBooks companies: checked 21 August 2026 against a Canadian file, and Intuit publishes no region list. Caribooks works with Canadian and US companies. For the rest, check before you commit: none publish a region list.
You work in French
Documentation for the other options is English only. Caribooks runs and answers in French.
You are building a product on top of QuickBooks
Composio, or Intuit's open-source server. Caribooks is a finished product, not a building block.
Quick answers
Does QuickBooks have an MCP?
Yes, two things from Intuit, and neither is a hosted server over the whole ledger. The open-source server on GitHub runs on your machine and needs a developer account. The connector inside Claude and ChatGPT is one click but limited to sales documents, a profit and loss and a cash flow statement, and it is US only. The hosted, full-ledger options are third party: Meridian's, free, and Caribooks, paid.
Is there a free QuickBooks MCP server?
Three, each with a catch. Intuit's open-source server is free but you host it and register a developer app. Meridian's is free and hosted, with one user per client company. Composio is free to 100,000 tool calls a month but expects code around it. Caribooks is paid, with 14 days to decide.
Can these tools change my books?
It depends, so check before you connect. The official connector writes on the sales side. Intuit's open-source server writes everywhere unless you set its restriction flags. Meridian lets you choose read-only or read-write per company. Caribooks starts read-only, and deletions, voids and sends need an explicit confirmation.
Does the official connector work in Canada?
No. A Canadian QuickBooks company cannot attach it (checked 21 August 2026 against a Canadian file). Intuit publishes neither a region list nor a timeline; if your books sit outside Canada, test it yourself. Canadian books go through one of the other options. Caribooks works with both.
Is my accounting data used to train models?
Intuit states that QuickBooks data reached through its connector is not used to train Claude. Caribooks keeps no accounting data on its servers and your books train no model. Meridian says it keeps no copy of your books, and CData says nothing is persisted on its side. What your assistant does with the conversation is a separate question.
