What a custom connector is

Muse comes with a list of connectors. For a service that isn't on that list, Meta's help center says you can ask Muse to create a custom connector, and Muse guides you through it.

You add Rebbel in Muse as a custom MCP connector, and you can remove it whenever you like.

What Rebbel adds to Muse

Rebbel is a marketing department rather than a caption writer: a brand guide built from your website, a strategy from your goals, campaigns drafted in your brand's voice, and the accounts you connect on rebbel.io to publish to. Once Rebbel is added, Muse can call Rebbel's tools: draft posts, approve them and publish to your connected accounts.

The rule that matters most does not change with the app you ask from: nothing publishes and no money is spent until you approve it, and that is checked on Rebbel's server, not by a setting you might forget. Muse has its own approval settings, which are Meta's; Rebbel's approval gate is separate and always on.

What to expect

On September 26, 2026 we added Rebbel to a free Muse account this way, signed in and approved, and asked Muse to list our Rebbel brands, which it did. From there it's the same Rebbel as everywhere else: ask for posts, review them, approve, and Rebbel publishes.

The step-by-step guide carries the date we last went through it. Publishing itself goes through the accounts you connect in Rebbel, on rebbel.io.

Who it's for

  • Owners and small teams who already use Muse and want to try Rebbel from it.
  • Anyone who wants to approve every post before it goes out.

Set it up

  1. Send Muse a message with Rebbel's address and select Connect on the card it shows.
  2. Read Muse's notice, sign in to Rebbel and approve access.
  3. Ask Muse for this week's posts.

Good to know

  • You add Rebbel in Muse as a custom MCP connector.
  • Nothing is posted until you approve it.
  • You can remove Rebbel from Muse at any time in Settings, under Connectors.

Common questions

How do I add Rebbel to Muse?

You add it in Muse as a custom MCP connector, then sign in to Rebbel to approve access.

Can Rebbel post from Muse without my approval?

No. Rebbel's publish and schedule tools refuse any post that hasn't been approved first, whether you ask from Muse or the dashboard.

Does it cost anything?

Rebbel is free to start: every new account gets its brand guide, strategy and first post free, with no credit card; a 7-day free trial covers the rest. We tested on a free Muse account.
