MCP server for Google Sheets - read, write, and query spreadsheet data
npm install google-sheets-mcpMCP server for Google Sheets - read, write, and query spreadsheet data.
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.)
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
``bash`
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.
`bash`
claude mcp add --transport http google-sheets-mcp http://localhost:3000/mcp
This server acts as an OAuth proxy to Google:

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/register
2. returns the Google OAuth client credentials/authorize
3. redirects to Google, encoding the client's callback URL in state/callback
4. receives the code from Google and forwards to the client's callback/token
5. proxies token requests to Google, injecting client credentials/mcp
6. 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.
