Google Multi-Account Connector

Several Google accounts in one Claude connector.

Claude's first-party Google connectors hold one account each. This server holds as many as you link — a personal Gmail and a work one, their calendars, Drives, contacts and tasks — and lets Claude search and act across all of them at once, or any one of them by name.

What it can do

• Gmail — search, read, draft, send, label, archive, trash. Permanent deletion is not requested and not possible.
• Calendar — a merged timeline across every account, plus event creation, responses, and free-slot suggestions.
• Drive — search, read (including text inside Office files and PDFs), create, edit, share, trash. Every outward action has an undo.
• Contacts — read-only, so "email Ann" resolves to an address.
• Tasks — read and write, across accounts.

How access works

You sign in with Google, then link each account you want reachable. Accounts you link are reachable by you and nobody else — every credential this server issues carries your identity, and every request is scoped to it.

Connect it
