How the Popover API, Navigation API, Invoker Commands, View Transitions, and other new browser APIs change the game for AI agent interaction — and how to use them to make your site agent-friendly.
Agentic browsers are here. ChatGPT Atlas, Perplexity Comet, Chrome’s Auto Browse, Vercel’s agent-browser — the list grows every month. But while plenty of ink has been spilled on the agent side of the equation, there’s been surprisingly little attention paid to a question that matters just as much: how do modern web platform APIs affect what agents can and can’t do on your site?
At least 60 SEO-related MCP servers now exist as of March 2026, spanning the full spectrum from keyword research to local SEO to AI visibility tracking. The ecosystem has matured rapidly since mid-2025: seven major SEO platforms have shipped official MCP servers (Ahrefs, Semrush, SE Ranking, DataForSEO, Serpstat, SimilarWeb, and Google Analytics), while Google Search Console alone has attracted 20+ community implementations. The most important finding for practitioners: official MCP servers from Ahrefs and Semrush are now remote-hosted with OAuth, meaning zero local setup — a significant usability leap. However, several third-party servers scrape data without authorization and should be avoided. Below is every SEO MCP server found, organized by category, with honest assessments of each.
In the early days of the web, “cloaking” was a dirty word. It conjured images of black-hat SEOs serving keyword-stuffed gibberish to search engine spiders while presenting a pristine, albeit often irrelevant, page to human users. It was a deception, a slight of hand designed to game the system. Today, as we stand on the precipice of the Agentic Web, the concept of cloaking is being reimagined, rehabilitated, and repurposed. We are moving away from deception and towards Agent Experience Optimization (AXO).
In our previous analysis, Effect of Nofollow on LLM Training, we established a grim reality for the privacy-conscious webmaster: AI training bots do not respect the rel="nofollow" attribute.
For two decades, nofollow was the gentlemen’s agreement of the web. It was a digital “Do Not Enter” sign that search engines like Google and Bing respected to manage authority flow (PageRank) and combat spam. It was a protocol built for an era of retrieval, where the primary value of a link was the endorsement it carried. If you didn’t want to endorse a site, you added the tag, and the “juice” stopped flowing.
