Websites are closing their doors to AI agents

In recent weeks, users of services like Meta's Muse, xAI's Grok, OpenAI's Dots, and Instinct have reported blocks preventing their AI agents from performing tasks across top websites. Yelp told TechCrunch that it only allows AI agents that pay for its data licensing program, while Delta Air Lines is preventing them from booking tickets. JPMorgan Chase and Charles Schwab have also confirmed that they're blocking AI agents from accessing accounts due to security concerns. Amazon said that "continued access" by Muse violates its site policies. Cloudflare now blocks AI shopping agents by default on any page that shows an ad. There is no opt-out directive for agents yet, only a block. AI training has grown to 52% of crawler traffic on Cloudflare's network, up from 22% last year. Meta has taken a different route, partnering with retailers like Walmart, Gap, Sephora, Best Buy, and others, allowing Muse to shop on their sites. For a founder, distribution now depends on bilateral deals and data licenses more than on agents loading pages freely. Blocked tasks often fail without a visible cause, so reliability dashboards should count refused sessions, not only completed ones. Budget for licensing fees and partner integrations before assuming an agent can reach a site on its own.
