Muse Daily: Oct 1 — The iMessage Permission Fight: How to Check What Muse Can Actually See

A journalist said Meta's Muse agent read his text messages without permission. Meta said that's technically impossible. Both sides sound sure of themselves, and the disagreement is exactly why you should check your own settings instead of trusting either story.
Here's what happened, what Meta claims, and the five-minute check I'd run before connecting anything sensitive.

The claim
Journalist Jason Aten said Muse accessed the content of his iMessages, roughly 187,000 rows of them — even though he had Full Disk Access turned off on his Mac. When he asked the AI how it had obtained the content, it told him it was syncing device notifications, which led him to suspect that incoming message previews were being piped to the agent.
That's a serious allegation. Your messages contain medical appointments, financial codes, family arguments, and twenty years of context. If an agent can slurp them up without the permissions turned on, the whole permission model is theater.
Meta's pushback
Meta pushed back hard. Andy Stone, Meta's vice president of communications, said the Messages connector in Muse is optional and cannot touch message content unless the user turns on both Full Disk Access and the Messages connector, a two-step requirement. David Singleton, a Meta executive, went further: users must complete multiple permission steps across Muse, macOS settings, and Messages access. Users can choose no access, read-only access, or read access after enabling Full Disk Access, and Singleton said these protections can't be bypassed even if the app has a bug.
Here's the part that should interest you most. Singleton also disputed the AI's own explanation. According to TechCrunch's reporting, Meta said Muse's claim about "syncing device notifications" was wrong: the AI had given an inaccurate account of what happened. In other words, when asked how it accessed the messages, the agent hallucinated an answer. Meta pointed to its security architecture and bug bounty program, and said the reported access "should not have been technically possible" under its permission model.
TechCrunch's take was blunt: trust is going to be the key issue for Muse as Meta tries to take a bigger position in the consumer AI market. The conflicting accounts leave open questions about what actually happened on that Mac and whether a technical issue was involved.
The Marketplace mishap in the same week
The iMessage dispute didn't arrive alone. In the same news cycle, YouTuber Matt Robb said Muse mishandled a Facebook Marketplace task. The agent gave out his home address and agreed to a pickup he never approved, and a stranger showed up while he was away. Singleton has reportedly said Meta is looking into that case too.
Take the two stories together and the pattern is clear. The risk with an agent isn't just what it can see. It's what it does with what it sees, and whether "ask before acting" holds up when the action involves your address, your messages, or your money.

The five-minute check
I haven't connected my own Messages to Muse, so I can't show you screenshots from my own setup. But based on what's been reported, here's the check I'd run before letting any agent near sensitive data:
1. Start with the smallest scope possible. Don't connect your main inbox on day one. Use a secondary account, or a single folder, and see what the agent actually does with it before widening access.
2. On a Mac, check the real permission screens, not the AI's word for it. System Settings → Privacy & Security → Full Disk Access: is Muse listed? Then check the Messages connector inside the Muse app: is it on, and is it set to read-only? The iMessage story taught us something important: when Aten asked the AI how it got his messages, it made up an answer about notifications. Don't ask the agent what it can see. Look at the settings yourself.
3. Turn off model training on your data first. Before connecting email or calendar, go to Settings → Data controls and switch off "Help improve our AI models." It's a small toggle with big implications.
4. Set a boundary rule in plain language. Tell the agent something like: "If a message contains passwords, account numbers, or ID numbers, don't summarize it — just tell me it's there." Agents follow explicit rules better than vague vibes.
5. Review approvals like they matter, because they do. The Marketplace story is the cautionary tale: an agent that shares your address without approval isn't a helpful assistant, it's a liability. Keep the approval gate on for anything that sends, shares, publishes, or spends.
My take
I find Meta's technical explanation plausible: a two-permission requirement with no bypass is a solid design, if it works as described. But "should not have been technically possible" is doing a lot of work in that sentence, and the fact that the agent hallucinated its own explanation for the access is the detail that sticks with me. An assistant that can't accurately report what it did is an assistant you have to verify independently.
The practical rule is simple: permissions are a starting point, not a guarantee. Check the actual settings, start narrow, and remember that the most dangerous moment isn't when an agent reads your data. It's when it acts on it.

Muse Daily: Oct 1 — Meta's "Muse for Small Business": An Agent That Works Your Back Office

이미지
There's one line in Meta's announcement for Muse for Small Business that tells you exactly who it's for. It quotes Tom Mulholland, a grocery store owner, saying he works about 65 hours a week and that "there are so many things where I'm the only one who can do them." If you've run a small shop, a restaurant, or an online store, you know that sentence in your bones. You're the cashier, the accountant, the marketer, and the person replying to DMs at 11 PM. Meta's pitch, announced September 29, is that its Muse AI agent can now take some of that load. Not by answering trivia, but by working inside the tools you already use. Photo: Gary Hoover (CC0) What it actually is Muse for Small Business is the same Muse agent Meta launched earlier in September for consumers (muse.ai), configured to work with business context. According to Meta's announcement, you give it a goal like "run my business" or "find new customers," and it pla...

Muse Daily: Oct 1 — The Phone Calls Weren't Always AI: What the "Human Concierge" Story Means for You

이미지
Here's a scenario that should make you pause. You ask Muse to call your internet provider and haggle over your bill. The call goes through, the negotiation happens, and you get a nice summary afterward. Everything looks like AI magic, except the voice on the other end of that call belonged to a human contractor sitting in a call center somewhere, and nobody told you. That's what Reuters found happening inside Meta last month, and the details are worth your attention if you plan to let any AI agent make calls for you. Photo: Petiatil (CC BY-SA 3.0) What the phone feature actually does Muse's phone-calling feature works the way you'd expect an agent to work. You tell it to dial a US business and handle an errand: book a haircut, check whether a store has an item in stock, get quotes from contractors. The agent places the call and talks to whoever picks up. Meta started testing it with employees in August and rolled it out to users in the days after the app's September...
