+# Changelog

+
+## 1.0.0 — initial release
+
+- Added the `quickbooks-online` plugin, the opt-in for the QuickBooks Online MCP server that Cursor hosts and credentials.
+- Carries no MCP server definition: the server is Cursor-side, so installing the plugin is the whole configuration.
+- Auth is Cursor-managed OAuth against Intuit, authorized per company file.
+- Logo: QuickBooks' official mark, from `quickbooks.intuit.com`.

+# QuickBooks Online
+
+Cursor plugin that connects agents to [QuickBooks Online](https://quickbooks.intuit.com) — Intuit's cloud accounting product — through a [Model Context Protocol](https://modelcontextprotocol.io/) server that Cursor hosts and credentials.
+
+Read a company file's accounting data: invoices, bills, expenses, payments, customers and vendors, the chart of accounts, journal entries, and the standard financial reports.
+
+## Install
+
+1. Open **Cursor Settings → Plugins**.
+2. Search for **QuickBooks Online**.
+3. Click **Install**, then sign in to Intuit when Cursor prompts you.
+
+Or run `/add-plugin quickbooks-online` in chat.
+
+## MCP
+
+This plugin ships no `mcp.json`, and that is deliberate.
+
+Every other connector in this repository either points at a vendor's hosted endpoint or runs a package locally over stdio, so it carries its own server definition. QuickBooks Online does not: Cursor runs the server, and the plugin exists only as the opt-in that turns it on for your account. Installing the plugin is what makes the server available; there is no command to run, no endpoint to reach, and no API key or client secret to paste.
+
+One consequence worth knowing: because the server is not declared here, you will not find it in a local `mcp.json` and you cannot point another MCP client at it. It is reachable from Cursor only.
+
+## Before you connect
+
+Nothing to prepare. Cursor owns the OAuth client, so you do not need an Intuit developer account or an app of your own.
+
+You will be asked to sign in to Intuit and pick a company. Authorization is per company file — connect once per company you want agents to reach, and grant only the ones you intend to expose.
+
+## What agents can do
+
+| Category | Capabilities |
+| --- | --- |
+| Accounts | Chart of accounts and company information |
+| Contacts | Customers, vendors, and employees |
+| Sales | Invoices, credit memos, and payments received |
+| Purchases | Bills, expenses, purchase orders, and payments made |
+| Banking | Bank transactions and journal entries |
+| Items | Products, services, and tracking categories |
+| Reports | Profit and loss, balance sheet, and cash flow statement |
+
+The server is the source of truth for tool names and schemas.
+
+## Notes
+
+- Access follows whatever the signed-in Intuit user can see. The connector cannot reach a company file that user has no access to.
+- QuickBooks Online and QuickBooks Desktop are different products. This connector is for QuickBooks Online.
+- Disconnecting is two independent steps: uninstalling the plugin stops Cursor from offering the server, and revoking the connection in Intuit's account settings ends Cursor's access to your data.
