Personal AI agents are ushering in a new era of consumer AI that goes well beyond simply answering questions. Tools like Meta's Muse, Instinct, ChatGPT's Dots, and similar offerings can now take real action on a user's behalf — booking flights, reserving dinner tables, ordering groceries — all without requiring any technical know-how to configure OpenClaw or another agent on a personal computer.

Yet as consumers embrace these agents, they're frequently hitting a wall: the website on the receiving end of a request blocks the AI from finishing the task. Most recently, Amazon started blocking Meta's Muse AI agent from its retail site, cutting the agent off from browsing or purchasing anything in its product catalog. The problem extends well beyond Amazon or Muse, though. Complaints surfacing across social media show that users' agents are regularly running into similar roadblocks. Some blocks are deliberate, as with Amazon, while others stem from conventional anti-bot defenses that websites use to guard against spam and malicious traffic. For the end user, there's no way to tell whether a block is accidental on the site owner's part — leaving them frustrated with both the retailer or service provider and the agent attempting to complete the transaction. (NBC also reported that Walmart encountered this issue during its own AI agent testing.)

However, a Walmart spokesperson told us these blocks weren't intentional. In fact, Walmart is partnered with Muse, a partnership announced at Meta's Connect developer conference in September. The company said it wants to be wherever its customers are, and that now includes being reachable through AI agent experiences. The problem Walmart customers keep encountering (see below) is that the site displays a button that must be clicked to verify a visitor is human. If that process gets interrupted, the verification can fail, and the agent gets ejected. This points to a broader issue: the technology we currently rely on to verify humans and shield websites from spam and bots may not suit the agent-first era of the web we're entering. To tackle this, industry players — including Meta, Walmart, Stripe, Sierra, Genesys, Rocket, NiCE, and Decagon — have started collaborating on an open standard that would define how AI agents communicate with businesses, making it easier to distinguish good bots acting on a user's behalf from bad ones. According to a Meta blog post, this protocol will focus specifically on agent-to-agent communication for online commerce purposes.

In the meantime, consumers are left confused. While Walmart is at least making an effort to be accessible through AI agents, other companies are less enthusiastic or haven't fully adopted the technology. Flight booking, for instance, is one of the primary use cases being promoted for agents, yet many users have reported airlines rejecting their agents' requests. Delta told us it is taking measures to shield customers from unauthorized automated activity, and that any opening to AI agents would need to be done with "security and the customer experience in mind."

"While Delta does not currently have a partnership or integration that enables a third-party AI agent to shop for or book Delta flights on a customer's behalf on our digital platforms, we're continuing to evaluate how new technology, including external AI agents, could enhance the way customers engage with Delta," said Delta's General Manager of Global Communications, Heena Chavda, responding to our questions about whether it was blocking agents, as some users complained. United wasn't as forthcoming as Delta, but a spokesperson directed us to a section of its Terms of Use policy stating that users agree "not to use any robot, spider, other automatic device, or manual process to monitor or copy this website or the content contained therein or for any other unauthorized purpose without United's prior written permission." (United did not answer a follow-up question about whether it was blocking specific personal AI agents like Muse.)

Complaints from early adopters on social media have named a range of brands reportedly blocking AI agents, including Yelp, eBay, Zillow, Pizza Hut, Adidas, and various airlines. Some believe the blocking activity has ramped up recently. A few people even reported that eBay suspended their accounts over their use of agentic AI. Another person complained that Google kicked out Instinct while it was cleaning up their Gmail inbox.

Despite the momentum behind getting agents to book restaurant tables and handle other tedious chores, Yelp told us it doesn't allow non-human traffic on its platform unless the agent has paid for access to Yelp's content and data through its data licensing program. That means agents attempting to use the site to get a quote, add a user to a waitlist, or book a table will likely fail without a formal partnership with Yelp. Its policies instead restrict unauthorized agents and actions, such as automated scraping and model training. Adidas, Zillow, and Pizza Hut either didn't respond or declined to comment by the time of publication. One major player in this space is Cloudflare, which provides sites with protection against AI agents that might be training on their data or conducting other automated activity. Some suspect Cloudflare and similar content delivery networks (CDNs) are currently disrupting Muse traffic. This is tied to a change to crawler defaults on September 15, which lets site owners block AI training while permitting other types of bots. Existing sites previously configured to block AI bots for security reasons were then shifted to block AI agents on any pages containing ads. When we asked Cloudflare whether it had any insight into the blocking of personal AI agents like Muse and others, the company said it had no specific data to share at this time, pointing us instead to its free public data hub, Cloudflare Radar. The site shows the rise in bot activity (which Cloudflare has also addressed before), but it doesn't distinguish between good bots and bad ones. Cloudflare also has a vested interest in reducing AI traffic to websites, since it now operates a marketplace where AI bots must pay for the data they access. It recently began testing a new web browser built specifically for AI agents. Given how quickly the space is evolving, Meta's decision to form specific brand partnerships for Muse access appears to be the right approach, as does its focus on new standards. This way, it assures customers that its agent, at least, is welcome at these partners' sites — so any access issues would be reportable bugs. Meta also maintains a list of "connectors" (i.e., partners) within the Muse app, which keeps growing. Many of Meta's newly announced partners haven't appeared on this list yet. But with Muse's rapid expansion, which now includes partnered tools for small businesses, a larger reorganization of Muse's connector list is likely coming soon.

"Turning away a personal agent means turning away the customer behind it. We'd rather work with businesses to address the underlying concerns than see them lose that customer," Meta said in its announcement about the newly revealed plans to develop a standard. "There is a path that is good for users and good for businesses. It starts with clear norms, gives businesses more predictable control, and evolves toward a more efficient way for agents to work together."
