All your calendars, in Muse

Meta Muse can use outside tools through MCP connectors. Synced is one connector for all of your calendars: every Google and Outlook account you've connected, merged, with booking, invitation replies and a task list Muse can work from.

Connect Meta Muse Why one connector

  • Google and Outlook together

    One connector instead of one per provider, with duplicates merged.

  • Meetings across companies

    Muse can find a time with people at other companies and book it with a clash check.

  • A to-do list it can manage

    Muse can add tasks, plan them into free time and mark them done on the same list you see in Synced.

Connect Meta Muse

  1. 1. Create a Synced API key

    In Synced, open Settings → Integrations and choose Generate New API Key. Copy the MCP Server URL shown under it; it already contains the key, so treat it like a password.

  2. 2. Add a custom connector in Muse

    Where your Muse app offers custom connectors, add a new one, name it Synced and paste the URL. Muse sends it to Synced over HTTPS.

  3. 3. Ask Muse

    Start with "Which calendars do you see?" to confirm it's reading Synced.

Server URL format:

https://api.meetsynced.com/functions/v1/mcp?api_key=sk_live_your_key

Meta's documentation for custom connectors is still thin and the option isn't available in every Muse app. We haven't tested every Muse version; if yours has no custom connector option, the same URL works in Claude and ChatGPT.

Then ask

  • “What's on my calendars tomorrow?”
  • “Find an hour with dan@globex.com next week.”
  • “Add 'renew the domain' to my tasks, due Friday.”

Questions

Can Meta Muse read my Outlook calendar?
Through Synced, yes: Synced connects to Microsoft for you and serves your Outlook calendars to Muse over MCP together with Google.
Does Muse need a separate connector for each calendar?
No. Connect your accounts to Synced once; the single Synced connector gives Muse all of them.
Is it safe to give Muse my calendar?
The key is scoped (calendar:read, calendar:write, contacts:read), every tool is labelled as read-only or not, and you can revoke the key in Synced at any time.
