Before you let an AI agent into your accounts

Meta’s Muse arrived in Singapore on 28 October. It is free, it links to Gmail, Instagram, Shopee, Grab and Agoda, and it can send messages and buy things for you. A chatbot only talks. An agent acts, using your name. Six checks before you link anything that belongs to the business.

the short version

  • Muse is made for a person, not a company. Try it on your own errands first: travel, your calendar, comparing prices.
  • Link one account at a time, with the least access it offers. Read-only email is enough to start.
  • Keep customer chats, staff records, the business bank account and government logins out of it.
  • Set it to ask before it sends, buys or opens a website.
  • Know where the off switch is before you need it.

six checks

  • 1
    accounts

    Start with your own errands, not the shop’s

    good start
    Your personal calendar, a trip you are planning, a price check on Shopee or Lazada.
    email
    Gmail can be linked read-only or read-and-write. Pick read-only until you have watched it work for a few weeks.
    keep out
    Business banking, payroll, Corppass and other government logins, and the folder with your staff records.

    Make it ask before anything leaves

    where
    In Muse, open Settings, then Permissions. Web access has two choices: “Ask for some actions” and “Always ask”.
    pick
    “Always ask” for the first month. It is slower, but you see every site it wants to open.
    read it
    When it shows you a message before sending, read the recipient line as well as the text. A reply to the wrong customer cannot be taken back.

    Customer details stay out

    why
    Your customers gave you their names, numbers and addresses to buy from you. Handing those chats to another company’s AI is using their data for something they never agreed to.
    the law
    Singapore’s Personal Data Protection Act still applies when a tool does the reading. If unsure, check the PDPC site or ask whoever handles data protection for you.
    in practice
    If your customer chats sit in your personal Messenger or Instagram, don’t link those accounts.

    money

    Don’t give it the company card

    how it pays
    Meta says Muse never sees your card number or passwords and asks before every purchase.
    still
    Agents misread a request now and then: the wrong date, the wrong size, two of something. If you want to try buying, use a personal card with a low limit.
  • 5
    staff

    Decide the rule before your staff find it

    likely
    It is free and comes from Meta, so some of your team will have it on their phones within weeks.
    one line
    Write down what they may and may not link for work. Customer chats, supplier prices and staff matters are the usual “not” list.
    same rule
    Use the same line for every personal AI agent, not just this one. More are coming.

    off switch

    Know how to stop it

    unlink
    Settings, then Connectors, then Connected. Remove any account you no longer want it to touch.
    scheduled
    Agents keep working after you close the app. Recurring jobs are listed under Settings, then Permissions, then Scheduled tasks.
    check
    The side panel keeps a log of everything it did. Skim it once a week while you are still getting to know it.
    training
    Look under Data controls for whether your chats can be used to train Meta’s models, and turn that off if you prefer.

what it can and can’t do for a shop

One business use stands out. Muse says it can draft, post and schedule on Facebook Pages you manage, and that it shows you an approval card first. If you keep a shop Page going on your own, that could save some evenings. Read every post before you approve it.

When I tried it on 29 October with my own accounts, linking WhatsApp only let me chat with Muse there. It could not read or answer my other WhatsApp chats, so it is no help with customer enquiries on WhatsApp. I saw no way to answer a Page’s customer messages, and no link to Microsoft 365 or Outlook. Meta says more connectors are being added in stages, so check the Connectors list for what is there today.

One more thing worth knowing: in September, Reuters reported internal Meta posts saying that during launch-week testing an agent got around its guardrails and exposed personal photos. Meta says it has worked on security and that mistakes can’t be ruled out. That is the reason for checks 2 and 6.
