+- Added the `quickbooks` MCP server, running Intuit's official `quickbooks-online-mcp-server` locally over stdio via `npx github:intuit/quickbooks-online-mcp-server`.
+- Auth uses an Intuit Developer app's client ID and secret plus a refresh token and realm ID supplied by the user; the environment selects sandbox or production.
+- Logo: QuickBooks's official "qb" mark on the brand green, from the `IntuitDeveloper` GitHub organization.

+# QuickBooks
+
+Cursor plugin that connects agents to [QuickBooks Online](https://quickbooks.intuit.com) through Intuit's official [Model Context Protocol](https://modelcontextprotocol.io/) server, run locally by Cursor.
+
+Read and write a QuickBooks Online company's accounting data — customers, vendors, invoices, estimates, bills, payments, journal entries, items, and financial reports.
+
+## Install
+
+1. Open **Cursor Settings → Plugins**.
+2. Search for **QuickBooks**.
+3. Click **Install**, then set the Intuit app credentials, refresh token, realm ID, and environment (below).
+
+Or run `/add-plugin quickbooks` in chat.
+
+## MCP

+  }
+}
+```
+
+Intuit does not publish a generally available hosted MCP endpoint. Its official server is [`intuit/quickbooks-online-mcp-server`](https://github.com/intuit/quickbooks-online-mcp-server), a local stdio server that is not published to npm, so the plugin installs it straight from GitHub with `npx` and builds it on first run. It authenticates with OAuth 2.0 credentials from an app you register on the Intuit Developer Portal; Intuit does not offer per-user API keys, and the plugin ships no client secret of its own.
+
+There is also a hosted server at `mcp.quickbooks.intuit.com`, but it is an invitation-only pilot for Intuit App Partners that requires IP allowlisting and restricted MCP scopes provisioned by an Intuit Solution Engineer, so this plugin does not use it.
+
+## Before you connect
+
+1. Sign in at [developer.intuit.com](https://developer.intuit.com) and create an app (or open an existing one) with the **QuickBooks Online Accounting** scope.
+2. Copy the **Client ID** and **Client Secret** from **Keys & Credentials**. Development keys work with sandbox companies; Production keys are needed for a live company.
+3. Get a refresh token and realm ID for the company you want to connect:
+   - **Sandbox:** open the [OAuth 2.0 Playground](https://developer.intuit.com/app/developer/playground), select your app and the `com.intuit.quickbooks.accounting` scope, authorize a sandbox company, and copy the **refresh token** and **realm ID** it returns.
+   - **Production:** Intuit rejects `localhost` redirect URIs for production apps, so complete the one-time handshake with a public HTTPS callback. The server's [Production Setup](https://github.com/intuit/quickbooks-online-mcp-server#production-setup) section documents doing this with a clone of the repo, `npm run auth`, and an ngrok tunnel; the tokens it writes to `.env` are the values you need.
+4. Set all five values in **Dashboard → Plugins → Configure**, with **environment** set to `sandbox` or `production` to match the keys and company you used.
+
+Refresh tokens expire after 100 days without use. The server refreshes them on demand, so a plugin that is used regularly stays connected; one that sits idle past the window needs a new token.
+
+## What agents can do
+
+| Category | Capabilities |
+| --- | --- |
+| Customers & vendors | Customers, vendors, employees, and company info |
+| Sales | Invoices (including PDF download), estimates, sales receipts, credit memos, refund receipts, and payments |
+| Purchases | Bills, bill payments, purchases, purchase orders, and vendor credits |
+| Banking | Deposits, transfers, and journal entries |
+| Items & settings | Items, accounts, classes, departments, terms, payment methods, tax codes, tax rates, tax agencies, preferences, and attachments |
+| Time | Time activities |
+| Reports | Balance sheet, profit and loss, cash flow, trial balance, general ledger, customer sales, customer balance, aged receivables and payables, and vendor expenses |
+
+Tool names follow a `{verb}_{entity}` convention (`create_invoice`, `search_customers`, `get_balance_sheet`). The server is the source of truth for tool names and schemas.
+
+## Notes
+
+- This is a local stdio server, so `npx`, Node.js, and `git` have to be available on the machine running Cursor. The first launch clones and compiles the server, which takes a little while; later launches reuse the `npx` cache.
+- The server is an early preview from Intuit. Some capabilities and configuration may change before general availability.
+- Intuit rotates refresh tokens. The server persists the rotated token to a `.env` file inside its install directory and prefers that over the configured value on later starts, so the value in Cursor's configuration can go stale without breaking the connection. Clearing the `npx` cache discards that file; if the connection then fails with an authorization error, generate a fresh refresh token and update the plugin configuration.
+- Tool calls run against the single company the refresh token was issued for. To work with several companies, reconfigure the plugin with that company's token and realm ID.
+- To narrow the surface, add `QUICKBOOKS_DISABLE_WRITE`, `QUICKBOOKS_DISABLE_UPDATE`, or `QUICKBOOKS_DISABLE_DELETE` set to `"true"` to the server's `env`; read tools are always registered.
+- The npm packages `quickbooks-mcp`, `@pipeworx/mcp-quickbooks`, and `@mindstone/mcp-server-quickbooks` are community servers. None of them is Intuit's server.
