Muse + Cuiar

The café's logins stay on the café's computer.

  • Cuiar channels work today
  • Routines work today
  • Muse is rolling out in the US
Set it up Get Cuiar

Muse runs errands from WhatsApp and the Muse app, on a secure computer in Meta's cloud. That computer has none of the café's logins: the supplier portal, the booking pages, the till dashboard.

Cuiar keeps them in a workspace on the café's computer. Meta does not document a way to add an MCP server to Muse, so this page says what works today and what you can try.

Muse to Cuiar is not tested. Meta's help does not say if a custom connector can use an MCP server or the Cuiar API.

A custom connector sheet for the Cuiar API fills in line by line: base URL, method, a hidden key and the events URL. Then a stamp lands on it that reads Not tested.

Setup

What works today, and what to try.

The first two steps need no Muse at all. The last two are a test, and the API needs Cuiar Pro or Team.

  1. 1

    Today: give tasks from your phone

    Link Telegram or Slack to Cuiar, or use your private task address. Write the task there. The result, and any request for approval, comes back to the same chat.

    cuiar channels link telegram   # a code for the Telegram bot
cuiar channels email           # your private address for tasks
  2. 2

    Today: put the checks on a schedule

    cuiar routines create "Weekly sales" --schedule "0 8 * * 1" --workspace cafe \
  "Sign in to the Square dashboard. Read last week's sales by day and the top 10 items, and compare the totals with the week before."
  3. 3

    To try: a custom connector

    Muse can make a custom connector for a service that is not in its list. Ask for it in chat, and give the key only when Muse asks for it for its Secure Credentials Store.

    Create a Custom Connector for the Cuiar API. Start a task with POST https://api.cuiar.com/v1/tasks, the header Authorization: Bearer <key> and a body like {"task": "...", "workspaceId": "cafe"}. Then read GET /v1/tasks/{id}/events?wait=30 until the task ends.
  4. 4

    To try: set the permission

    In Muse, open Settings, Permissions and set the connector to Always ask.

Route

Until a connector is tested, use Cuiar's own channels.

Muse runs in Meta's cloud and has no documented MCP setting. Cuiar's channels and routines carry the work today, from the same phone.
