New to Muse?Muse is Meta's AI assistant. Daycal is an app you add to it, and once it is on, you can ask Muse to do this for you: set up and maintain a booking page for trips, holidays, focus time and daily limits. It takes about two minutes and you can turn it off any time.

Is it safe to connect?

What Muse can see: You sign in to your own account with it, so Muse can reach what that account allows. Read what it asks for before you agree.

Before it acts: Read what Muse plans to do before you approve it, and remove the app from Muse when you stop using it.

How to add it to Muse

Daycal is not in Muse's Connectors list yet, and it needs you to sign in with your Daycal account. Apps that need this kind of sign-in usually cannot be used from a Muse chat yet. Follow it here and we will tell you when it reaches Muse.

https://daycal.io/mcp

Not in Muse's Connectors list yet. Muse can still use it: its page gives you a request to paste into Muse.

Also use it in ChatGPT or Claude

Daycal is a remote MCP server, so any assistant that can add a custom connector by link can use it. Same link, same tools.

Add it to ChatGPT
  1. 1

    Open ChatGPT settings

    In ChatGPT, open Settings, then Connectors (called Apps & Connectors on some accounts).

  2. 2

    Turn on developer mode

    Under Advanced settings, switch on Developer mode. That is what lets you add a connector by link.

  3. 3

    Create the connector

    Choose Create, give it a name, paste the link as the MCP server URL, and save. If it needs a sign-in, ChatGPT asks for it here.

  4. 4

    Use it in a chat

    Start a chat, open the tools menu, pick the connector, and ask. ChatGPT asks before it runs a tool the first time.

Custom connectors need a paid ChatGPT plan, and on Team, Enterprise and Edu accounts only an admin can add them. Our "Working" label means the server answered us; it cannot tell whether your plan lets you add it. All connectors that work in ChatGPT

Add it to Claude
  1. 1

    Open Claude settings

    In Claude, open Settings, then Connectors.

  2. 2

    Add a custom connector

    Choose Add custom connector, give it a name, and paste the link.

  3. 3

    Connect and use it

    If it needs a sign-in, Claude sends you to it. Then turn the connector on in a chat from the tools menu and ask.

Custom connectors are available on paid Claude plans; on Team and Enterprise accounts an admin may need to add them. Our "Working" label means the server answered us; it cannot tell whether your plan lets you add it. All connectors that work in Claude

Screening looks for known threats and hidden instructions at the time of the check, and runs again weekly and whenever the tool list changes. It cannot see the server's code, so only connect what you need and review what Muse asks to do. How screening works.

Tools

This endpoint requires sign-in before it lists tools, so there is no public tool catalog.
