This is a standalone OAuth integration for reading and writing Google Sheets without needing an MCP server. You can pull spreadsheet data in text, CSV, or JSON formats, update specific cell ranges, append rows, and search across your sheets. It handles authentication through your system keyring and auto-refreshes tokens. The write commands support both parsed formulas and raw text input depending on whether you want Google to interpret your values. One catch: it requires a Google Workspace account, so personal Gmail users are out of luck. If you're already scripting against spreadsheets and want something lightweight that doesn't require running a separate server, this does the job.
