Connect Multiple Gmail Accounts to Grok Bot
Want Grok Bot working across more than one Gmail account? Connect them to Carly, add Carly to Grok Bot once, and one Bot works across all of your inboxes at once. Grok Bot takes a second Google account by design too, but users spent this week unable to get Google to authorize the plugin at all, and every Bot you run shares the same set of logins, so no Bot gets an inbox of its own.
1. Add your Gmail accounts to Carly
- Sign in at carlyassistant.com.
- Open carlyassistant.com/integrations.
- Find Gmail, click Connect, and authorize the account.
- Click Connect again for the next one, and keep going for as many accounts as you want.
A Google Workspace account may need administrator review. Ask the Workspace administrator to approve the connection, then finish authorization.
Carly connects to thousands of apps, so while you are on that page you can add your calendars, files, CRM, and anything else you want Grok Bot to reach through the same connector.
2. Add Carly to Grok Bot
- Select Plugins in the Grok Bot sidebar, or tap your avatar and choose Plugins on mobile.
- Add Carly’s remote MCP server,
https://carlyassistant.com/mcp/. - Finish the authorization in the browser tab that opens. If it sits on Waiting for authorization, use Reopen.
- Sign in to the Carly account holding the Gmail connections.
- Confirm Carly appears under Installed.
Grok Bot takes remote MCP servers rather than local ones, and Carly’s is hosted, so it qualifies. Grok Bot runs on your Cursor account, so there is no separate login, and team plans inherit Cursor’s MCP policy.
What one Bot can do afterwards
- Search personal and work Gmail in the same task.
- Compare threads sitting in different company accounts.
- Produce a daily summary grouped by inbox.
- Draft or send from the exact address you choose.
- Label, move, or archive in the correct account.
- Keep the routing intact when another Bot picks up the work.
Nothing is merged. Each mailbox keeps its own credentials, and Carly keeps them individually addressable.
Two Gmail accounts, one shared set of logins
Grok Bot reaches Gmail through Cursor’s plugin marketplace, not through anything xAI built. The Gmail plugin is a Cursor-verified wrapper around Google’s own remote MCP server, and more than one Google account is the intended design. The plugin’s page carries an Add Another Account control, and Cursor staff pointed a user straight at it on Aug 28, 2026. Authorization is where it comes apart.
Three reports on Cursor’s forum stack up. On Aug 4, users found Google plugins authenticating in the Local environment and failing in the Cloud one, with a 400 invalid_request on a cursor:// redirect. One of them ruled the plugin out by wiring Google’s Gmail server straight into mcp.json: 29 tools locally, identical failure in the cloud. Grok Bot only ever runs in the cloud. On Aug 14 came the second-account report, where the new slot flips to Added, reverts to Authorize a second later, and settles at authentication required with zero tools. It has had no reply. On Aug 28 a third thread landed with Google refusing outright: “This app is blocked. The app tried to access sensitive info in your Google Account.” Staff flagged it to the team the same day, and other users replied that they were hitting it too.
The official workaround is the part worth keeping. Cursor staff told that user to authorize Gmail from Cursor instead, because that path is unaffected and the connection is shared with Grok Bot. The fix for a broken login in one product is a login in another, on the same account, which is the whole shape of the thing.
The shared browser next to Carly
| Need | Grok Bot’s Gmail plugin or shared browser | Carly plugin |
|---|---|---|
| Reach one Gmail account | Yes | Yes |
| Hold several Gmail accounts | Supported by design, blocked by an open auth bug | Yes |
| Give each account its own permissions | No, one tool list covers every account | Yes, per connected account |
| Stop one Bot from reaching a client inbox | No, connectors are account-wide and xAI rules this out explicitly | Every action names its account, so an approval rule can gate the client inbox |
| Send from a named account | Whichever account the tool or browser session lands in | Yes, with that account’s permissions |
| Add Outlook mailboxes alongside | One Microsoft account in the Outlook plugin | Yes, in the same connection list |
| Survive a handoff to another Bot | The next Bot inherits every login | Yes, routing stays by address |
| Keep account-specific work running on a schedule | Routines run on the shared machine | Yes, across every connected account |
Carly gives Grok Bot one account-aware toolset where the accounts stay apart. Carly offers free Zapier-style workflows; AI agents start at $35/month.
Quick fixes
| Problem | Fix |
|---|---|
| A Bot acted in the wrong inbox | Route through Carly and name the full address in the instruction |
| Two Bots need different access | Give every connection to Carly, which reaches all of them and keeps each separate |
| The browser session expired mid-task | Reconnect in Carly so the routing survives the session |
| Sends go out before you see them | Add a Require Approval rule for external email |
| Workspace blocks authorization | Ask the Google Workspace administrator to approve Carly |
Frequently asked questions
Can Grok Bot connect two Gmail accounts at once?
By design, yes: the plugin has an Add Another Account control, and Cursor staff confirmed on Aug 28, 2026 that further Google accounts go in there. In practice that week, users could not complete Google authorization from Grok Bot at all, and the separate report of a second account reverting seconds after it was added has had no reply since Aug 14. Whatever does connect is account-wide, shared by every Bot you own behind one tool list, so the inboxes are reachable but not separable. Connecting each inbox to Carly is what keeps them individually addressable.
Do separate Bots keep my inboxes apart?
No. xAI states that the computer is isolated to your account rather than to an individual Bot, and that Bots working in parallel do not get separate security boundaries.
Does connecting Carly give every Bot access?
Carly is added as a plugin, and each Google identity is a separate authorized connection inside Carly. Instructions name the target address, so the account a Bot acts in is explicit rather than whatever the browser happens to be signed in to.
Will this work on a Cursor team plan?
Since Aug 26, 2026 Grok Bot comes with every paid Cursor plan, Pro, Pro+ and Ultra, plus self-serve Teams and SuperGrok. Carly connects the same way on any of them.
Can I mix Gmail and Outlook accounts?
Yes. Connect every identity to Carly, on either provider, and one request covers all of them.

See what people say
"Before Carly, I relied on a Calendly link, but the whole process felt impersonal and not very professional. Carly changed that by handling all the back-and-forth, so I'm no longer stuck in endless email threads trying to line up schedules.
Now Carly reaches out to candidates, shares my real-time availability, lets them pick a slot, then sends a Zoom link and drops it straight into my calendar. She sends reminders to both of us before each call, which has significantly reduced no-shows and last-minute confusion.
On top of scheduling, Carly acts like a full executive assistant, sending me my schedule the night before so I can prepare for each call. It reminds me of the old x.ai assistant, but Carly is noticeably smarter, faster, and better suited to my healthcare recruitment business."
