# Sheets MCP

Let Claude read, edit, format and chart your Google Sheets. Ask for a new column, a cleaner layout or a chart, and Claude makes the change directly in your spreadsheet.

Free and open source · Runs on your computer · Works in Claude Desktop and Claude Code

If Sheets MCP saves you time, a ⭐ on GitHub helps other people find it.

## Install

### Claude Desktop (easiest, no setup)

1. Install [Claude Desktop](https://claude.ai/download) and sign in.
2. Download **[sheets-mcp.mcpb](https://sheetsmcp.io/downloads/sheets-mcp.mcpb)**.
3. Double-click the file, then click **Install** in Claude Desktop.

New to Claude Desktop? Follow the [step-by-step setup guide](https://sheetsmcp.io/?utm_source=github&utm_medium=readme&utm_campaign=install#install).

The extension works in both the Chat and Code tabs. For long, multi-step jobs, the Code tab is the more dependable choice: it runs everything on your computer.

### Claude Code

Requires [Node.js](https://nodejs.org) 18 or newer. Run:

```bash
claude mcp add --scope user google-sheets -- npx -y @sheetsmcp/server
```

Then start a new Claude Code session.

## Sign in

The first time Claude uses Google Sheets, a Google sign-in page opens in your browser:

1. Choose your Google account.
2. Google shows **"Google hasn't verified this app"**. Click **Advanced**, then **Go to Sheets MCP**.
3. Click **Continue** to allow access to your spreadsheets.

To use more than one Google account, ask Claude to *"sign in to another Google account"*. When you paste a sheet link, Sheets MCP uses whichever of your accounts can open it.

To open the Google sign-in in a particular browser without changing your default, add `"browser": "Google Chrome"` (or another app name) to `~/.sheets-mcp/settings.json`.

If your company's Google Workspace blocks the sign-in, your Workspace admin can allow Sheets MCP under **Admin console → Security → API controls**.

## Try asking

In Claude Desktop, click **+** and choose **Get started with Google Sheets** for a quick tour. When more than one Google account is connected, Claude asks which account to use before creating a spreadsheet, or when a sheet can be opened by more than one of your accounts.

- "Summarize this sheet: <link>"
- "Add a Profit column that subtracts Cost from Revenue, and format it as currency"
- "Chart spending by month in this sheet: <link>"
- "Freeze the header row, bold it, and auto-fit the column widths"
- "Summarize revenue by region and product in a pivot table"
- "Change that chart to a line chart and move it next to the table"
- "Create a new spreadsheet called Trip Planner"
- "Open my budget sheet" (works for sheets you've used with Sheets MCP before)
- "Undo that"

## Live preview

In Claude Desktop, Claude opens a live preview of your sheet in the chat while it works. You see each range it reads and each change it makes as it happens, charts included, and the preview folds away when Claude is done. **Open in Sheets** jumps to the same cells in Google Sheets.

After updating Sheets MCP, quit and reopen Claude Desktop so it loads the new preview.

## Privacy

Sheets MCP runs on your computer. Your Google sign-in is stored only on your computer (in `~/.sheets-mcp`), and requests go straight from your computer to Google. There is no Sheets MCP server in between. It asks Google for access to your spreadsheets only, not the rest of your Drive. To find a sheet by name, it keeps a list of the spreadsheets you've used with it in `~/.sheets-mcp/recent.json` on your computer; delete that file to clear the list. Spreadsheet data Claude reads becomes part of your Claude conversation. See the [privacy policy](https://sheetsmcp.io/privacy).

To disconnect, ask Claude to *"sign out of Google Sheets"*, or remove Sheets MCP at [myaccount.google.com/permissions](https://myaccount.google.com/permissions).

## Command line (optional)

```bash
npx @sheetsmcp/server auth                      # sign in to a Google account
npx @sheetsmcp/server accounts                  # list signed-in accounts
npx @sheetsmcp/server accounts default <email>  # choose the default account
npx @sheetsmcp/server accounts remove <email>   # sign out an account
```
