Can Meta Muse Read My Emails? What It Sees (2026)
Yes, if you connect the mailbox. Muse reads, searches and summarizes mail in the Gmail and Outlook accounts you connect, and its Gmail connector now takes more than one account. You choose per connector whether Muse can only read or can also write, and background sync lets it keep up with new mail after you close the app.
Carly turns what it reads into work done. Every new email in every Gmail and Outlook account is read the moment it lands and handled by your rules: the urgent one texts your phone, the attachment is filed in the right folder, the client conversation is logged in your CRM, and your other apps stay current.
Set it up in Muse
- Connect every inbox at carlyassistant.com/integrations, personal and work, Gmail and Outlook.
- Paste the prompt below into Muse. It adds Carly as a custom connector and lists every mailbox it can see.
- 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 it into Muse’s secure credential prompt, not the chat.
- Ask across all of them:
Read everything from the accountant, the school and the landlord across all my inboxes this month and tell me what still needs an answer.
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.What Muse reads
In Muse’s connector settings, the Gmail connector lists four read permissions: drafts, labels and filters, emails, and search. Each linked account sits under the same connector, with an Add account button for the next one. The Outlook Mail connect screen says Muse will access “message content, attachments, sender info and metadata.”
Meta’s Alexandr Wang says you decide for each connector “whether it can just read your data, or read and write it,” and can disconnect any of them at any time. A read-only connection is how you keep Muse from ever sending.
What Meta says about your data
- Not for ads. Wang says Muse runs in a secure virtual machine and that Meta doesn’t use your data “for ads or anything other than to make Muse great for you.”
- Training is on by default. WIRED reports users are opted in to AI training by default and cannot switch memory off. Muse’s own connect screen notes that the info used for your tasks may be used to improve AI at Meta.
- Watch what it does. The same screen warns that “Muse may take unexpected actions. Monitor it carefully.”
Carly signs in to each account through Google’s or Microsoft’s own sign-in, never sees your password and does not train on customer data.
What reading turns into
Muse reading your mail means Muse can answer about it and act when it decides to. What it reads doesn’t automatically become a filed contract, a CRM entry or a text to your phone, and its free plan has a weekly usage limit that heavy inbox reading burns through.
| Muse on its own | Muse with Carly | |
|---|---|---|
| Gmail accounts it can read | Several | All of them, plus Outlook |
| Read-only option | Yes | Yes, untick mail:write on the key |
| Every new email handled by a fixed rule | No, Muse decides as it goes | Yes, the same way every time |
| Attachments filed into Drive or Dropbox | When you ask | Automatically |
| Client emails logged in your CRM | When you ask | Automatically |
| How you hear about the one that matters | A message in Muse | A text to your phone, by your rule |
Have every new email read and acted on
Carly reads each new message in every inbox you connect and acts on it by your rules. Turn these on from Muse once Carly is connected:
- Text me when an urgent email arrives. A real person waiting on you, a deadline or money sends a text to your phone.
- File attachments where they belong. Statements, contracts and receipts saved to the right Drive, Dropbox or Box folder as they arrive.
- Log client mail in your CRM. Each conversation lands on the right person in Carly’s CRM, HubSpot or Salesforce.
- Watch for one topic. “Tell me the moment anything about the Henderson closing comes in,” across every account.
- A morning brief across every inbox. New mail sorted into urgent, action needed and FYI, with today’s calendar on top.
Carly connects to thousands of apps, so what Carly reads can update the tools you already pay for. Free Zapier-style workflows; AI agents from $35/month. Get started.

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."
