Quickstart

Prerequisites

• A Google account with at least one spreadsheet in Drive
• An interactive MCP client such as Claude, ChatGPT, or Cursor

Steps

1. Create your Sheetbase account. Go to sheetbase.flonest.app and choose Continue with Google. Google is the only Sheetbase sign-in method.

2. Connect Google Workspace. Signing in identifies your Sheetbase account. Spreadsheet access is a separate permission. If the dashboard says Google Workspace — Not connected, choose Connect Google Workspace and approve Sheets and Drive access. The status will change to Connected.

Note

Sheetbase requests drive.readonly + drive.file — not full Drive access. It cannot read arbitrary Drive files outside the spreadsheets scope.

3. Add Sheetbase to Claude. Open Claude's custom connector form, name the connector Sheetbase, and enter:

   https://sheetbase.flonest.app/api/mcp

   Claude opens Sheetbase's browser authorization flow. Sign in, review the request, and allow the connection.

   See the full Claude Desktop guide for a step-by-step walkthrough.

4. Use another interactive client (alternative). In ChatGPT, Cursor, or another client that supports custom remote MCP servers, open its connector or MCP settings and add the same endpoint:

   {
     "mcpServers": {
       "sheetbase": {
         "url": "https://sheetbase.flonest.app/api/mcp"
       }
     }
   }

   The client should discover Sheetbase OAuth and open the browser authorization flow. See the full Cursor guide for Cursor-specific steps. Use a dashboard API key only for scripts, CI, or custom agents that cannot use OAuth.

5. Run your first command. In your connected client, try:

   "List all my Google Sheets spreadsheets"

   Sheetbase calls list_spreadsheets and returns your Drive file list. Then try:

   "Read the first 10 rows of Sheet1 in [paste a spreadsheetId]"

   You now have a fully wired AI ↔ Google Sheets pipeline.
