MCP Demo Day: How 10 leading AI companies built MCP servers on Cloudflare
Today, we're excited to collaborate with Anthropic, Asana, Atlassian, Block, Intercom, Linear, PayPal, Sentry, Stripe, and Webflow to bring a whole new set of remote MCP servers, all built on Cloudflare, to enable Claude users to manage projects, generate invoices, query databases, and even deploy full stack applications — without ever leaving the chat interface.
Since Anthropic’s introduction of the Model Context Protocol (MCP) in November, there’s been more and more excitement about it, and it seems like a new MCP server is being released nearly every day. And for good reason! MCP has been the missing piece to make AI agents a reality, and helped define how AI agents interact with tools to take actions and get additional context.
But to date, end-users have had to install MCP servers on their local machine to use them. Today, with Anthropic’s announcement of Integrations, you can access an MCP server the same way you would a website: type a URL and go.
At Cloudflare, we’ve been focused on building out the tooling that simplifies the development of remote MCP servers, so that our customers’ engineering teams can focus their time on building out the MCP tools for their Continue reading
With Its Llama API Service, Meta Platforms Finally Becomes A Cloud
A lot of companies talk about open source, but it can be fairly argued that Meta Platforms, the company that built the largest social network in the world and that has open sourced a ton of infrastructure software as well as datacenter, server, storage, and switch designs, walks the talk the best. …

D2DO271: Public Vs. Private Cloud In 2025
The shine has been coming off public cloud for awhile. Cloud costs remain high, complexity is growing, and public cloud interoperability is difficult. And while there’s talk about moving back to private cloud, that migration presents its own costs and complexities. To help us navigate the challenge that is cloud in 2025, we welcome Mark...

Bringing streamable HTTP transport and Python language support to MCP servers
We’re continuing to make it easier for developers to bring their services into the AI ecosystem with the Model Context Protocol (MCP). Today, we’re announcing two new capabilities:
Streamable HTTP Transport: The Agents SDK now supports the new Streamable HTTP transport, allowing you to future-proof your MCP server. Our implementation allows your MCP server to simultaneously handle both the new Streamable HTTP transport and the existing SSE transport, maintaining backward compatibility with all remote MCP clients.
Deploy MCP servers written in Python: In 2024, we introduced first-class Python language support in Cloudflare Workers, and now you can build MCP servers on Cloudflare that are entirely written in Python.
Click “Deploy to Cloudflare” to get started with a remote MCP server that supports the new Streamable HTTP transport method, with backwards compatibility with the SSE transport.
The MCP spec was updated on March 26 to introduce a new transport mechanism for remote MCP, called Streamable HTTP. The new transport simplifies how AI agents can interact with services by using a single HTTP endpoint for sending and receiving responses between the client and the Continue reading
OSPF Summary LSA Loop Prevention
A networking-focused entity known only as humblegrumble sent me the following question after reading my When OSPF Becomes a Distance Vector Protocol article:
How do A1 and A2 know not to advertise a Type-3 summary LSA generated from area 1 prefixes back into area 1?
He’s right. There is no “originating area” information in the type-3 LSA, so how does an ABR know not to reinsert the type-3 LSA generated by another ABR back into the area?
TL&DR: The OSPF route selection process takes care of that.

William Stanley Jevons was one of the founders of neoclassical economics in the mid-nineteenth century. In the aftermath of the great railway mania of the mid 19th century he observed that the total consumption of coal had actually increased when technological progress improved the efficiency of steam engines. Jevons Paradox observes that that improvements in efficiency of resource utilisation can act as a positive incentive to increased resource consumption, exceeding the reductions that would be anticipated due to this greater efficiency. How does this relate to the Internet and the current issues relating to Internet Centrality?Breaking APIs or Data Models Is a Cardinal Sin
Imagine you decide to believe the marketing story of your preferred networking vendor and start using the REST API to configure their devices. That probably involves some investment in automation or orchestration tools, as nobody in their right mind wants to use curl or Postman to configure network devices.
A few months later, after your toolchain has been thoroughly tested, you decide to upgrade the operating system on the network devices, and everything breaks. The root cause: the vendor changed their API or the data model between software releases.

I wanted to test a loop prevention when propagating summary LSA across areas scenario (more about that in another blog post) using the lab topology I developed for the When OSPF Becomes a Distance Vector Protocol article.
I started the lab with the FRRouting routers and configured OSPF area ranges. Astonishingly, I discovered that the more-specific prefixes from an area appear as summary routes in the backbone area even when the area range is configured. When I tried to reproduce the scenario a few days later, it turned out to be a timing quirk (I didn’t wait long enough), but my squirrelly mind was already investigating.
Boat Monitoring System
As I travel further north on the canals the mobile signal coverage is gradually getting worse so I decided to build a monitoring solutions to help with deciding where to moor. My initial idea was to use an Intel NUC or RaspberryPi with a 12v PSU, but then a friend told me about how he was monitoring his home lab using kubernetes on an old android phone, it sounded like the perfect solution.
Targeted by 20.5 million DDoS attacks, up 358% year-over-year: Cloudflare’s 2025 Q1 DDoS Threat Report
Welcome to the 21st edition of the Cloudflare DDoS Threat Report. Published quarterly, this report offers a comprehensive analysis of the evolving threat landscape of Distributed Denial of Service (DDoS) attacks based on data from the Cloudflare network. In this edition, we focus on the first quarter of 2025. To view previous reports, visit www.ddosreport.com.
While this report primarily focuses on 2025 Q1, it also includes late-breaking data from a hyper-volumetric DDoS campaign observed in April 2025, featuring some of the largest attacks ever publicly disclosed. In a historic surge of activity, we blocked the most intense packet rate attack on record, peaking at 4.8 billion packets per second (Bpps), 52% higher than the previous benchmark, and separately defended against a massive 6.5 terabits-per-second (Tbps) flood, matching the highest bandwidth attacks ever reported.
In the first quarter of 2025, Cloudflare blocked 20.5 million DDoS attacks. That represents a 358% year-over-year (YoY) increase and a 198% quarter-over-quarter (QoQ) increase.
Around one third of those, 6.6 million, targeted the Cloudflare network infrastructure directly, as part of an 18-day multi-vector attack campaign.
Furthermore, in the first quarter of 2025, Cloudflare blocked approximately Continue reading
How the April 28, 2025, power outage in Portugal and Spain impacted Internet traffic and connectivity
A massive power outage struck significant portions of Portugal and Spain at 10:34 UTC on April 28, grinding transportation to a halt, shutting retail businesses, and otherwise disrupting everyday activities and services. Parts of France were also reportedly impacted by the power outage. Portugal’s electrical grid operator blamed the outage on a "fault in the Spanish electricity grid”, and later stated that "due to extreme temperature variations in the interior of Spain, there were anomalous oscillations in the very high voltage lines (400 kilovolts), a phenomenon known as 'induced atmospheric vibration'" and that "These oscillations caused synchronisation failures between the electrical systems, leading to successive disturbances across the interconnected European network." However, the operator later denied these claims.
The breadth of Cloudflare’s network and our customer base provides us with a unique perspective on Internet resilience, enabling us to observe the Internet impact of this power outage at both a local and national level, as well as at a network level, across traffic, network quality, and routing metrics.
In Portugal, Internet traffic dropped as the power grid failed, with traffic immediately dropping by half as compared to the Continue reading
