Is it safe to connect my Gmail account to Claude?

The connection runs through Google's own OAuth flow, so Claude never sees your password. You can revoke access at any time from your Google account's security settings, the same way you would revoke any third-party app.

Does Claude send emails automatically once Gmail is connected?

No. Claude drafts a reply and shows it to you first. Sending anything requires your explicit approval, it never fires off an email on its own.

How do I set up a Gmail MCP server for Claude Code?

You create OAuth credentials in Google Cloud Console, run the server's one-time auth command in a terminal to authorize your Gmail account through a browser popup, then register the connector with Claude Code using its install command. After that one-time setup, every new session has the connector available.

How many emails can Claude process in one request?

There's no hard limit, but past roughly 50 emails at once it helps to narrow the request by label, sender, or date range so Claude isn't trying to reason over an overwhelming amount of text in a single pass.

Can Claude read attachments in my Gmail?

It depends on the file type and what the connected server exposes, but plain text content in the email body and thread history is reliably readable. Complex attachments are better handled by asking Claude to summarize the surrounding thread first.
