Can Meta Muse Schedule Meetings for You?
Yes. Ask Muse to find 30 minutes next week and it checks availability on the calendars you’ve connected, picks a slot, writes the invite and sends it once you approve. That’s scheduling you start. The scheduling that starts with someone else, a client who wants to book, six people who need one slot, an email asking to meet while you’re on a plane, is where you need more.
Carly handles both sides. Muse books across every Google and Outlook calendar you own through Carly, and Carly answers meeting requests on its own, runs booking pages and group polls, logs every meeting in your CRM, and drafts the follow-up after.
Set it up in Muse
- Add every calendar and inbox at carlyassistant.com/integrations, Google and Microsoft, work and personal.
- Paste the prompt below into Muse. It adds Carly as a custom connector.
- 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.
- Book something:
Find 45 minutes next week that’s free on all my calendars, send Claire an invite from my work address, and add a video link.
Carly setup prompt for Muse
Paste this into Muse. It adds Carly and walks you through connecting your calendars.
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.How scheduling works in Muse
Muse’s Google Calendar connector can read your calendars and events and “check availability,” and it takes more than one Google account. Inc reported that Muse “could already schedule meetings” at launch. A typical booking:
- You name the person, the length and a rough window.
- Muse checks your availability and picks a slot.
- It drafts the invite and the email that goes with it.
- You approve. Meta says Muse checks with you before sensitive actions like sending an email.
Where it stops
- No booking link. There’s nothing to put in your email signature so a client can pick a slot without three rounds of “does Thursday work?”
- No group poll. Getting six people onto one time means collecting their availability yourself.
- Requests wait for you. When someone emails asking to meet, Muse answers once you ask it to. Carly answers on its own.
- Google and Outlook are separate connectors. A slot that looks free on one can be taken on the other unless both are connected and checked.
| Muse on its own | Muse with Carly | |
|---|---|---|
| Calendars checked before offering a time | The ones Muse checks | Every Google and Outlook calendar, every time |
| Booking link for clients | No | Yes, free |
| Group poll for several people | No | Yes, free |
| Replies to meeting requests by email | When you ask | Automatically, with open times |
| Meeting logged in your CRM | When you ask | Automatically |
| Books callers on the phone | No business line | Yes, with Carly’s phone line |
What scheduling looks like with Carly
Carly is built for advanced calendar work, and it handles the scheduling that starts with someone else. Set any of this up from Muse once Carly is connected:
- Answer meeting requests. When someone emails asking to meet, Carly replies with times open on all your calendars, each bookable in a click, or with your booking link.
- Booking pages. A link clients use to pick a time, checked against every calendar you connect. Free.
- Group scheduling. A poll for several people, then the meeting goes on everyone’s calendar. Free.
- Every booking in your CRM. New bookings land on the right person in Carly’s CRM, or in HubSpot.
- A briefing before each meeting. Who the outside attendees are and what they’re likely after.
- Book callers while they’re on the line. Carly’s AI receptionist puts the appointment on your real calendar. Muse can set that up too.
Carly also has its own email address, so a client can write to it directly and it finds the time, books the meeting and sends the invite. Carly connects to thousands of apps. Free Zapier-style workflows; AI agents from $35/month. Get started.
Frequently asked questions
Can Meta Muse send calendar invites?
Yes, from the calendars you connect, once the connector has write access. Meta says Muse checks with you before sensitive actions like sending an email.
Can Muse find a time that works for everyone?
It checks your availability. Getting a group onto one time is what a poll is for, and Carly’s group scheduling does that part for you.
Does Muse have a booking link?
No. Carly’s booking pages are free and check every calendar you connect before offering a slot.
Can Muse reply to meeting requests automatically?
Muse answers a request when you ask it to. Carly answers new meeting requests on its own with times that are open on your calendars.
Can Muse schedule across my work and personal calendars?
Yes, if both are connected to Muse. Through Carly, every Google and Outlook calendar is checked together on every booking. See Can Meta Muse manage my calendar?

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."
