Can Meta Muse Manage My Calendar? (2026)
Yes. Muse’s Google Calendar connector reads your calendars, events and availability, books and deletes events, and now takes more than one Google account. Outlook Calendar is its own connector. What Muse does on your calendar happens when you ask, or when Muse decides something needs doing.
Carly adds the rules that run on their own. Travel time before every in-person meeting, a briefing before every call, events pulled from email, and meeting requests answered, across every Google and Outlook calendar you own. Each meeting gets logged in your CRM automatically, and the follow-up is drafted before you ask.
Set it up in Muse
- Add every calendar at carlyassistant.com/integrations: each Google and Microsoft account, with Calendar ticked.
- Paste the prompt below into Muse. It adds Carly as a custom connector and lists every calendar 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:
Block travel time before every in-person meeting on all my calendars from now on, and brief me 30 minutes before each client call.
Carly setup prompt for Muse
Paste this into Muse. It adds Carly and walks you through connecting every calendar.
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 does with your calendar
In Muse’s connector settings, the Google Calendar connector lists these permissions:
- Read: calendar sharing, calendars, events, and availability.
- Write: delete events, plus create, delete and share calendars (set to ask by default).
- Accounts: each linked Google account, with an Add account button.
Inc reported that Muse “could already schedule meetings, update your calendar, send emails” from launch. In practice: “What’s on tomorrow?”, “add the dentist from that confirmation email”, “push the 3pm to Thursday”, “invite Claire.”
Where it stops
It acts, it doesn’t keep rules. “Add travel time before every in-person meeting” is a standing rule. Muse can do it for the meetings you mention. Keeping it true for every meeting added next month is a different job.
Google and Outlook are separate connectors. Each holds its own accounts, so a conflict check that spans your Google work calendar and an Outlook client calendar depends on both being connected and Muse remembering to look at both.
It decides as it goes. Muse’s own connect screen warns that it “may take unexpected actions. Monitor it carefully.” That’s a lot of watching for the thing your whole week runs on.
No booking page. Muse works your calendar from the inside. There’s no link a client can use to pick a time.
| Muse on its own | Muse with Carly | |
|---|---|---|
| Google calendar accounts | Several | All of them |
| Google and Outlook checked together before booking | If both are connected and Muse checks | Every time |
| Travel time added automatically | When you ask | On every in-person meeting |
| Events added from email as it arrives | When you ask | Automatically |
| Meetings logged in your CRM | When you ask | Automatically |
| Booking pages | No | Yes, free |
What managing a calendar looks like with Carly
Advanced calendar work is one of the things Carly does best, because it follows your rules the same way every time. Turn these on from Muse once Carly is connected:
- Auto-block travel time. When a meeting has an address, Carly adds a block before it sized to the drive from wherever you were.
- Add events from email. Appointment confirmations, school events and invitations go straight onto the right calendar.
- Stop double booking. Every calendar is checked before a time is offered, across Google and Outlook.
- A briefing before each meeting. Who the outside attendees are and what they’re likely after.
- Every meeting in your CRM. The recap from your notetaker lands on the right people, with the follow-up drafted.
- A daily calendar briefing. Tomorrow’s schedule every evening, with anything that clashes flagged.
Scheduling is free in Carly too: booking pages, group scheduling and unlimited connected calendars. Carly connects to thousands of apps. 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."
