It turns out we’ve all been using MCP wrong. Most agents today use MCP by directly exposing the “tools” to the LLM. We tried something different: Convert the MCP tools into a TypeScript API, and then ask an LLM to write code that calls that API. The results are striking: We found agents are able […]

RSS feed for this sectionIntroducing new regional Internet traffic and Certificate Transparency insights on Cloudflare Radar
Since launching during Birthday Week in 2020, Radar has announced significant new capabilities and data sets during subsequent Birthday Weeks. We continue that tradition this year with a two-part launch, adding more dimensions to Radar’s ability to slice and dice the Internet. First, we’re adding regional traffic insights. Regional traffic insights bring a more localized […]
Announcing Cloudflare Email Service’s private beta
If you are building an application, you rely on email to communicate with your users. You validate their signup, notify them about events, and send them invoices through email. The service continues to find new purpose with agentic workflows and other AI-powered tools that rely on a simple email as an input or output. And […]
Choice: the path to AI sovereignty
Every government is laser-focused on the potential for national transformation by AI. Many view AI as an unparalleled opportunity to solve complex national challenges, drive economic growth, and improve the lives of their citizens. Others are concerned about the risks AI can bring to its society and economy. Some sit somewhere between these two perspectives. […]

Safe in the sandbox: security hardening for Cloudflare Workers
As a serverless cloud provider, we run your code on our globally distributed infrastructure. Being able to run customer code on our network means that anyone can take advantage of our global presence and low latency. Workers isn’t just efficient though, we also make it simple for our users. In short: You write code. We […]
A year of improving Node.js compatibility in Cloudflare Workers
We’ve been busy. Compatibility with the broad JavaScript developer ecosystem has always been a key strategic investment for us. We believe in open standards and an open web. We want you to see Workers as a powerful extension of your development platform with the ability to just drop code in that Just Works. To deliver […]
Automatically Secure: how we upgraded 6,000,000 domains by default to get ready for the Quantum Future
The Internet is in constant motion. Sites scale, traffic shifts, and attackers adapt. Security that worked yesterday may not be enough tomorrow. That’s why the technologies that protect the web — such as Transport Layer Security (TLS) and emerging post-quantum cryptography (PQC) — must also continue to evolve. We want to make sure that everyone […]
Giving users choice with Cloudflare’s new Content Signals Policy
If we want to keep the web open and thriving, we need more tools to express how content creators want their data to be used while allowing open access. Today the tradeoff is too limited. Either website operators keep their content open to the web and risk people using it for unwanted purposes, or they […]
Securing today for the quantum future: WARP client now supports post-quantum cryptography (PQC)
The Internet is currently transitioning to post-quantum cryptography (PQC) in preparation for Q-Day, when quantum computers break the classical cryptography that underpins all modern computer systems. The US National Institute of Standards and Technology (NIST) recognized the urgency of this transition, announcing that classical cryptography (RSA, Elliptic Curve Cryptography (ECC)) must be deprecated by 2030 […]
