Can Meta Muse Manage My Inbox? (2026)
Yes, as an assistant that improvises. Muse’s Gmail connector now holds more than one account and can read, search, draft, label, unsubscribe and trash, with background sync switched on. It asks before it sends. And its own connect screen is honest about the rest: “Muse may take unexpected actions. Monitor it carefully.”
Carly is the version you don’t have to watch. Add Carly to Muse once, and every email in every Gmail and Outlook account gets handled by your rules, the same way every time. Carly files the attachments into the right folder, logs client mail in your CRM, keeps your other apps current, and texts you when something can’t wait.
Set it up in Muse
- Connect every inbox at carlyassistant.com/integrations: Gmail and Outlook, personal and work, shared mailboxes too.
- Paste the prompt below into Muse. It adds Carly as a custom connector and checks that it can see all of your inboxes.
- When Muse asks for a key, open your Carly account page, click API keys, name the key “Muse”, leave every permission ticked and click Generate key. Paste the key into Muse’s secure credential prompt, never into the chat.
- Tell Muse the rule you want:
Set up a Carly workflow that files every new email in all my inboxes under my existing labels and folders, saves attachments to Drive, and texts me when something urgent arrives.
Carly setup prompt for Muse
Paste this into Muse. It adds Carly and walks you through connecting your inboxes.
Help me set up Carly. I'll add it to you myself: tell me exactly what to click for the app you are, one step at a time, and wait for me to confirm before moving on. If you can do the setup yourself (Claude Code, Codex, Muse, Grok Bot), go ahead, and ask me for any key in your secure credential prompt, never in the chat. Once it's added, walk me through connecting my accounts, check it worked by listing every mailbox and calendar you can see through Carly, and ask what I want to hand off first. The steps are below.
# Connect Carly to an AI app
> Carly connects to thousands of apps, from Gmail, Outlook and calendars to Slack, HubSpot and QuickBooks, and keeps working after a chat is closed: answering email, booking meetings, following up and running workflows the moment something happens.
MCP server: https://carlyassistant.com/mcp/ (streamable HTTP, OAuth)
## Setup
1. Add the Carly plugin (some apps call it a connector):
- ChatGPT: open https://chatgpt.com/plugins/plugin_asdk_app_6a67a26316b88191860222f918d4ec54 (or open Plugins and search "Carly"), add it, and sign in.
- Claude (claude.ai, Claude Desktop, or Cowork): open https://claude.ai/directory/carly, click Connect, and sign in.
- Claude Code: `claude mcp add --transport http --scope user carly https://carlyassistant.com/mcp/`, then /mcp, pick carly, and authenticate.
- Codex: `codex mcp add carly --url https://carlyassistant.com/mcp/`, then `codex mcp login carly`.
- Cursor: add {"mcpServers": {"carly": {"url": "https://carlyassistant.com/mcp"}}} to ~/.cursor/mcp.json, then sign in to carly from Customize.
- Muse: a custom connector to https://carlyassistant.com/mcp/ with a Carly API key as its bearer token. The key comes from carlyassistant.com/account (API key under Carly) and goes in Muse's connector settings, not in a chat message.
- Grok: grok.com/connectors > New Connector > Custom, paste https://carlyassistant.com/mcp/, and sign in.
- Grok Bot: a custom remote MCP server named carly at https://carlyassistant.com/mcp. Approve it and sign in.
- Perplexity: Plugins in the sidebar (or Customize > Connectors), then Add custom > Connector > Add MCP connector. Choose Remote, name it Carly, paste https://carlyassistant.com/mcp/, pick OAuth, check the box and click Add, then click the Carly card to sign in.
- Anything else: a remote MCP server (streamable HTTP) named carly at https://carlyassistant.com/mcp/. It signs in with OAuth.
Sign in with a Carly account, or create one at carlyassistant.com.
2. Once it's added, Carly's tools show up in the chat. If they don't, turn Carly on for the chat or start a new chat.
3. Connect accounts at https://carlyassistant.com/integrations. Under Accounts, click Connect Google or Connect Microsoft, pick the account and grant everything it asks for. If the page shows an email field instead, type the address, click Add Email, click Connect Google or Connect Microsoft on the new address, then Connect with Google or Connect with Microsoft. For an address that is already connected, open Manage access and click Connect next to anything missing. Repeat for every account, then connect any other apps.
4. To check it worked, ask Carly to list every connected mailbox and calendar.
5. Something to hand off first: "Check all my inboxes for anything that needs a reply today."
## Business calls and texts
Business SMS, business phone calls, voicemail and a team's voice and text agents are a separate connector, Carly Teams, at https://carlyassistant.com/team/mcp. It needs membership of a Carly organization and its own connection. Its setup is https://carlyassistant.com/team/mcp.txt.That is the whole setup. Watch it done in three minutes.
What Muse does with your inbox today
We opened Muse’s connector settings to see exactly what its Gmail connector can do:
- Several accounts. The Gmail connector lists each linked account with an Add account button.
- Read and search your mail, drafts, labels and filters.
- Write. Draft, send, unsubscribe, manage labels, mark read or unread, and move mail to or from Trash.
- Background sync, so Muse can keep working after you close the app. Meta says it comes back “when something changes or when it needs approval.”
Outlook Mail is a separate connector that Muse describes as “manage and organize your inbox.” Each permission can be set to allow or ask, and sending is set to ask out of the box.
Where it stops
It asks before it sends. Meta says Muse “checks with the person before sensitive actions like sending an email.” Good for a personal agent. It also means the routine “yes, Tuesday works” reply sits until you look at your phone.
It decides as it goes. Muse is an agent, not a rulebook. Today’s newsletter and tomorrow’s can land in different places, and Muse’s own warning is to monitor it carefully.
Gmail and Outlook are separate worlds. Each connector has its own accounts and permissions. One rule covering your Gmail, your Outlook and a shared mailbox isn’t something you set once.
The free plan has a weekly limit. Inbox work on every message burns through it fast. Paid plans buy more usage.
| Muse on its own | Muse with Carly | |
|---|---|---|
| Gmail accounts | Several | All of them |
| Gmail and Outlook under one set of rules | Separate connectors | Yes |
| Labels new mail | When Muse decides to | Every email, by your rules, the same way |
| Sends | Asks first | By your rules, or saved as drafts |
| Files attachments into Drive or Dropbox | When you ask | Automatically, as they arrive |
| Updates your CRM | When you ask | Automatically, on every client email |
| Business phone line | No | Yes, calls and texts |
What managing an inbox looks like with Carly
Carly is built to be reliable and endlessly customizable: it follows your rules, the same way every time, in every account you own. Turn any of these on by asking Muse once Carly is connected:
- Triage and file every email. Each new message lands under one of the labels, categories or folders that inbox already has. Promotions go to a junk label you pick.
- Text me when an urgent email arrives. A real person waiting on you, a hard deadline or money on the line sends a text to your phone.
- File attachments where they belong. Contracts, invoices and statements land in the right Drive, Dropbox or Box folder automatically.
- Update your CRM on every client email. The conversation is logged on the right person in Carly’s CRM, HubSpot or Salesforce.
- Draft replies to the emails that need you. In your voice, saved to Drafts.
- Chase threads that went quiet. Every weekday morning, a drafted nudge for each thread where you sent the last message.
Carly connects to thousands of apps, so every email can update the tools you already pay for. And if you’d rather Muse also answered the phone, it can do that through Carly too.

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."
