Qb Auto is an MCP server that gives Claude Code native tools for QuickBooks Online automation. It replaces large browser_snapshot round-trips with targeted DOM extraction (~200–500 tokens) and compound Playwright actions that complete entire workflows in one tool call.
Install Python 3.10+, the mcp and playwright packages, and a Chrome browser running with remote debugging on port 9222. Register the server with Claude Code by adding a quickbooks entry to ~/.mcp.json that points to server.py. Claude can then call any of the 15 tools directly.
It uses the standard MCP `stdio` transport and communicates with Claude Code via a subprocess.
Python 3.10+, the `mcp` and `playwright` packages, and a Chrome browser started with `--remote-debugging-port=9222`.
It connects to the Chrome browser via Chrome DevTools Protocol (CDP) on port 9222, then navigates to QBO and extracts data from the DOM using injected JavaScript.
No. All operations happen live in the user’s QBO session; the server only returns compact JSON results from the current page state.
Yes. Set the `CDP_PORT` variable in `server.py` to use a port other than the default 9222.
