Cloudflare Radar Researcher Is Here! Just Ask AI to Explore Internet Trends, Plus WebMCP Support

Hi everyone, it's Shii! There's a fresh update from Cloudflare Radar today, you can now chat with AI to explore internet trends. Let's dive in!

Cloudflare Changelog developers.cloudflare.com

What was announced?

According to Cloudflare's Changelog, Cloudflare Radar has added a beta AI assistant called "Radar Researcher." You can open Researcher from the header on any Radar page and ask questions by voice or text to get plain-language explanations of internet trends and traffic data.

Answers come back as interactive charts built from Radar API data, and if you select "Explain with AI" on an existing chart, you can start a conversation about that chart's underlying data and context. You can also get suggested follow-up questions, search through earlier conversations, and share conversations via shareable links.

Alongside this, Radar now supports WebMCP, which lets browser-based AI agents navigate Radar, search data, and use tools like URL scanning and domain lookup.

Why it matters

Radar has always been a free service for visualizing internet-wide traffic, attack activity, DNS trends, and more, but with so many kinds of data available, finding what you wanted usually meant knowing which chart type and filters to use.

Radar Researcher seems aimed at putting an "ask and it tells you" AI in between, so you can just ask in plain language without needing that prior knowledge. And WebMCP support is about letting AI agents themselves, not just humans, operate Radar directly to pull data, a sign that Cloudflare's own tools are catching up with a web increasingly used by AI agents.

What changes

Previously, using Radar meant hunting down the right chart and building your own filter conditions. Now you can just ask Researcher and get the trend you want explained directly.

• Open Researcher from the header and ask questions by voice or text
• Use "Explain with AI" on any chart to dig into its underlying data
• Search your conversation history, and share conversations via links
• With WebMCP support, AI agents can use Radar's data and tools like URL scanning and domain lookup directly

This looks like a welcome update both for people who just want a quick read on internet trends and for developers building AI agents.

Dive Deep

WebMCP is part of Cloudflare's broader push around MCP (Model Context Protocol), a mechanism that lets a website expose a structured set of "usable tools" for AI agents. Instead of an agent taking screenshots, analyzing them, and clicking around, a fairly unreliable approach, it can call the exposed tools directly, making its behavior more reliable.

For Radar, it looks like this mechanism is being used to let AI agents call existing features like URL scanning and domain lookup directly. The changelog itself didn't spell out detailed technical specs, but based on the phrase "browser-based AI agents can navigate Radar," it's reasonable to think AI agents can now operate the same Radar interface that people use in a browser.

Wrap-up

• Cloudflare Radar added a beta AI assistant called "Radar Researcher" that you can ask about internet trends and traffic data
• You can dig into individual charts with "Explain with AI," and search or share your conversation history
• Radar now supports WebMCP, letting browser-based AI agents navigate Radar and use tools like URL scanning and domain lookup
• A nice update both for anyone checking internet trends and for developers building AI agents that use Radar's data
