Common questions about Google Sheets MCP

What other Google Sheets MCP servers are there?

Most Google Sheets MCP servers are community projects or third-party services that you connect with your Google account.

Can Mammoth change my spreadsheet?

No. Connecting a sheet as a source gives Mammoth read-only access, so it reads your sheets but can't edit them.

Does it read every tab in my spreadsheet?

It reads the sheets you bring into Mammoth. Pick the tabs you want when you connect the spreadsheet.

How does my assistant get to my Google Sheets data?

You connect Google Sheets to Mammoth once. Mammoth keeps a copy of the data and updates it on demand or on a schedule. Your assistant asks Mammoth, not Google Sheets.

Are the numbers right?

Yes. Mammoth calculates totals, counts and averages itself and gives your assistant the result. The AI model doesn't add up the rows.

Which AI assistants work with it?

Claude on the web, Claude Desktop and Claude Code, ChatGPT, and VS Code. Cursor can't sign in yet, so use the Mammoth CLI there.

What does it cost?

The MCP server is on every Mammoth plan, including Free. The Free plan reads Google Sheets, so you can do all of this without paying.

Do I paste a password or API key into the chat?

No. You connect Google Sheets inside Mammoth and sign in to Mammoth from your assistant. No password passes through the model.

Can my assistant change things by mistake?

Every tool is labelled as read-only, a change you can undo, or one that deletes or sends data out. You can set your assistant to ask you before it uses anything that isn't read-only.
