Install

Add this to your client's MCP configuration (Claude Desktop: claude_desktop_config.json; Cursor: .cursor/mcp.json; VS Code and others use the same "mcpServers" shape).

NPM package google-sheets-mcp
Claude Code 
claude mcp add google-sheets -e 'GOOGLE_ACCESS_TOKEN=<your google_access_token>' -- npx -y google-sheets-mcp@1.2.1
JSON configuration (Claude Desktop, Cursor, VS Code) 
{
    "mcpServers": {
        "google-sheets": {
            "command": "npx",
            "args": [
                "-y",
                "google-sheets-mcp@1.2.1"
            ],
            "env": {
                "GOOGLE_ACCESS_TOKEN": "<your google_access_token>"
            }
        }
    }
}

Environment variables

google-sheets-mcp

MCP server for Google Sheets - read, write, and query spreadsheet data.

Use Cases

Data questions: "How many open deals are in the pipeline?" or "What's our total Q3 revenue?" → reads the spreadsheet and answers directly.

Quick expense entry: Snap a photo of a receipt → extracts the details and appends a row to your expense tracker.

Cross-tool status sync: "Check all our vendor Slack channels and update the tracking spreadsheet with their latest updates" → reads Slack, updates the sheet.

Data analysis: "Break down the Salesforce figures by region and compare against our events calendar" → pulls data from multiple sources into a spreadsheet for analysis.

(These are just examples - any workflow that needs spreadsheet data can use this. Use in combination with google-drive-mcp for finding files, deleting, comments, and sharing permissions.)

Setup

1. Create Google OAuth credentials
  1. Go to Google Cloud Console
  2. Create a new project (or use existing)
  3. Enable the Google Sheets API
  4. Go to APIs & Services → OAuth consent screen, set up consent screen
  5. Go to APIs & Services → Credentials → Create Credentials → OAuth client ID
  6. Choose Web application
  7. Add http://localhost:3000/callback to Authorized redirect URIs
  8. Note your Client ID and Client Secret
2. Run the server
GOOGLE_CLIENT_ID='your-client-id' \
GOOGLE_CLIENT_SECRET='your-client-secret' \
MCP_TRANSPORT=http \
npm start

The server runs on http://localhost:3000 by default. Change with PORT=3001.

3. Add to your MCP client

With the server running, follow the instructions on install-mcp, which generates the right config for your MCP client (Claude Code, Claude Desktop, Cursor, Cline, VS Code, and more).

Architecture

This server acts as an OAuth proxy to Google:

graph LR
    A[MCP client] <--> B[google-sheets-mcp] <--> C[Google OAuth/API]
  1. Server advertises itself as an OAuth authorization server via /.well-known/oauth-authorization-server
  2. /register returns the Google OAuth client credentials
  3. /authorize redirects to Google, encoding the client's callback URL in state
  4. /callback receives the code from Google and forwards to the client's callback
  5. /token proxies token requests to Google, injecting client credentials
  6. /mcp handles MCP requests, using the bearer token to call Google Sheets API

The server holds no tokens or state - it just proxies OAuth to Google.

Frequently asked questions

What is Google Sheets?

Allow AI systems to read, write, and query spreadsheet data via Google Sheets.

How do I install Google Sheets?

It runs on your machine. In Claude Code: claude mcp add google-sheets -e 'GOOGLE_ACCESS_TOKEN=<your google_access_token>' -- npx -y google-sheets-mcp@1.2.1. For other clients, paste the JSON configuration from this page into their MCP settings.

Does Google Sheets need an API key?

Yes. It expects GOOGLE_ACCESS_TOKEN, MCP_TRANSPORT, GOOGLE_CLIENT_ID, GOOGLE_CLIENT_SECRET, which you set in its configuration.

Is Google Sheets open source?

Its code is public on GitHub, but the repository does not declare a standard license.

Who maintains Google Sheets?

It is published by domdomegg. AI.tn lists it but does not maintain or endorse it.

From the official MCP Registry. Listing is not an endorsement: review a server's code and permissions before giving it access to your data.
