总览

今天的主线其实很清晰：AI agent 正在把“工具”的形态彻底改写。

一边是 Cloudflare 这种把 2500+ API 端点压缩成两个 MCP 工具（search()/execute()）的“Code Mode”；另一边是 GitHub/开源基金在强调“AI 软件供应链”得先补安全短板；再加上“Google API key 以前不算秘密、现在却能当 Gemini 凭证”的事故级变更，基本把 2026 年的开发现实讲明白了：你可以更快，但你必须更谨慎。

市场这边（用 Stooq 的最新快照）更像是背景噪声：指数在高位波动，油、金、汇率都给出一点“风险偏好并不稳”的信号。对做技术的人来说，直接可操作的点反而是：密钥治理、供应链安全、以及 agent 工具链的工程化（可控、可审计、可收敛上下文）。

重点条目

我今天最想你盯住的 5 条：

  • #8（Gemini API key 变“万能钥匙”）
  • #2（SASE 全链路后量子）
  • #1（Cloudflare API 的 MCP 两工具化）
  • #7（67 个关键项目的供应链加固结果）
  • #11（OpenSandbox：给 AI 应用准备的通用沙箱）

它们分别对应“凭证/边界/工具/依赖/执行环境”五个环节，拼起来刚好是一条完整的 agent 安全链路。

按分数分档

下面每条都给：标题 + 分数 + 关键标签 + 结论/要点（1-3 句；重要的会多写一点）。

S 档（9.0+）

条目 #8｜Public Google API keys can be used to expose Gemini AI data｜9.4 关键标签：#Security #Secrets #Gemini #Cloud #KeyManagement 结论/要点：过去“可以公开”的 Google API key，在启用 Gemini（Generative Language API）后，很多情况下等价于真实 AI 凭证。我的结论很直接：把 API key 当成密码对待，做一次全量清点、限制可用服务/来源、强制轮转，并把“是否启用 Gemini”纳入变更评审。

条目 #2｜Cloudflare One：全平台现代化后量子加密（PQ / hybrid ML‑KEM）｜9.1 关键标签：#Security #PostQuantum #SASE #ZeroTrust #Networking 结论/要点：这不是“某个点位支持 PQ”，而是把 PQ key agreement 延伸到更多 on-ramp/off-ramp（包括 IPsec/WAN）。对企业网来说，这是把“未来迁移”提前到今天做，尤其适合有“数据寿命很长”的组织。

A 档（8.0-8.9）

条目 #1｜Code Mode：用约 1000 tokens 让 agent 访问整个 Cloudflare API｜8.7 关键标签：#AI #MCP #DevTools #API #Sandbox 结论/要点：把“成千上万工具描述”压成 search()/execute() 两个工具，本质是在服务器侧跑受控代码，把上下文成本固定住。对 agent 工具链来说，这是一个可复用的范式：工具表越大越应该“代码化”，同时把执行沙箱隔离做好。

条目 #11｜alibaba/OpenSandbox（GitHub Trending）｜8.6 关键标签：#OpenSource #Sandbox #AI #Kubernetes #Runtime 结论/要点：面向 AI 应用的通用沙箱平台，统一 API + 多语言 SDK + Docker/K8s 运行时，方向很对。我的判断：未来做 agent 的“执行层”会越来越像这个——把环境隔离、资源配额、网络/文件权限变成一等公民。

条目 #7｜GitHub：67 个关键开源项目的 AI 供应链安全结果｜8.3 关键标签：#OpenSource #SupplyChain #Security #CodeQL #CVE 结论/要点：这类项目（语言运行时、网络库、CI/CD、数据科学栈）一旦出事，影响是跨行业的。结论：你自己的项目里，至少要把“关键依赖清单 + SBOM + 自动化扫描 + secrets 防泄露”做成默认配置。

条目 #10｜microsoft/markitdown（GitHub Trending）｜8.1 关键标签：#OpenSource #Docs #MCP #Python #Productivity 结论/要点：把 Office/文件等转换成 Markdown，并提供 MCP server，典型“给 agent 喂干净输入”的基础设施。做 RAG/agent 的团队，越早把文档入口标准化越省事。

B 档（7.0-7.9）

条目 #3｜vinext：一周用 AI 重建 Next.js（Vite 版 drop-in 替代）｜7.9 关键标签：#AI #Frontend #Vite #Nextjs #Performance 结论/要点：这篇更像一份“AI 时代工程方式”的实验报告：明确的规格（Next.js API）+ 强测试护栏 + 迭代节奏，AI 才能变成可持续生产力。对团队的启发：把测试/基准做扎实，你才敢让模型写更多代码。

条目 #4｜AWS Weekly Roundup：OpenAI×Amazon 战略合作等｜7.6 关键标签：#Cloud #AI #Partnership #Bedrock #Enterprise 结论/要点：AWS 叙事正在把“agent runtime / stateful context / 工具和数据源协作”推成平台能力。我的结论：云厂商的差异会从“模型谁多”变成“能不能把状态、权限、审计、成本做成可运营的默认件”。

条目 #5｜Microsoft & OpenAI 联合声明：合作条款不变｜7.2 关键标签：#AI #Cloud #Partnership #IP #Commercial 结论/要点：核心信息是“Azure 仍是 stateless OpenAI APIs 的独家云”+ IP/分成条款不变。对企业采购来说，这意味着短期内架构选择的“合规解释”不需要大改，但多云合作会越来越常态化。

条目 #6｜Visual Studio February Update（Copilot 测试生成/调试分析等）｜7.1 关键标签：#DevTools #Copilot #Testing #Debugging #DotNet 结论/要点：工具在把“写测试、看调用栈、性能剖析”变成对话式入口。团队层面别只看“写代码变快”，要同步改代码评审/测试策略，否则速度只会把缺陷放大。

条目 #9｜ClickHouse 官方 Kubernetes Operator（Apache-2.0）｜7.0 关键标签：#Kubernetes #Database #OpenSource #Operator #Reliability 结论/要点：把 ClickHouse 集群编排（Keeper、扩缩容、升级、TLS）收敛到 CRD/Operator。想把 OLAP 正式放进 K8s 的团队，这是“少走弯路”的路径，但要配合存储、备份与升级演练一起做。

C 档（6.0-6.9）

条目 #18｜AWS Tools for PowerShell v4 进入 maintenance mode｜6.8 关键标签：#AWS #PowerShell #SDK #Maintenance #Migration 结论/要点：v4 从 2026-03-01 起进入维护模式、2026-06-01 EoS，后续只有关键 bug/security 修复。结论：有历史脚本/自动化跑在 v4 的，别拖，按迁移指南尽快切到 v5，否则“突然踩到服务/区域变化”时会被动。

条目 #12｜anthropics/prompt-eng-interactive-tutorial（GitHub Trending）｜6.8 关键标签：#Prompting #LLM #Tutorial #Education 结论/要点：交互式提示词教程，适合团队内部做统一训练材料。如果你在推动“全员会用 agent”，这种可练习的教材比 PPT 更管用。

条目 #13｜servo/servo（GitHub Trending）｜6.6 关键标签：#Rust #BrowserEngine #OpenSource #Performance 结论/要点：Servo 继续作为 Rust 浏览器引擎的高性能实验田存在。对想做“嵌入式 Web 技术/自定义渲染管线”的团队，Servo 依然是值得长期跟踪的方向。

条目 #15｜WTI 原油期货（CL.F, Stooq）｜6.2 关键标签：#Markets #Commodity #Oil 结论/要点：最新快照收盘 72.33。对技术团队更现实的动作是把成本可观测性打通（尤其是云账单），用数据把“成本上涨”翻译成可运营指标。

条目 #16｜黄金（XAUUSD, Stooq）｜6.1 关键标签：#Markets #Commodity #Gold 结论/要点：最新快照收盘 5365.325。金价高位通常意味着避险需求还在；宏观不确定性下，安全/合规投入更容易被“事后追责”倒逼，不如提前做。

条目 #17｜美元兑人民币（USDCNY, Stooq）｜6.0 关键标签：#Markets #FX #CNY 结论/要点：最新快照收盘 6.88244。如果你有跨境计费或美元成本（云/模型 API），建议把汇率波动做进预算区间，而不是用一个固定点位拍脑袋。

条目 #14｜S&P 500 指数（^SPX, Stooq）｜6.5 关键标签：#Markets #Index #RiskOnOff 结论/要点：最新一日收盘在 6881.62（Stooq 快照）。高位运行意味着“坏消息的敏感度”会更高，做增长/出海业务的技术团队要更关注成本与回款。

小结（我自己的判断）

现在做 agent / AI 工具链，最容易踩的坑不是“模型不够聪明”，而是把边界当成小事：key、权限、执行沙箱、供应链、审计。今天的几条新闻几乎都在提醒同一件事：把这些做成默认项，你才敢放心把更多生产动作交给 agent。

Code Mode: give agents an entire API in 1,000 tokens

This post is also available in 日本語 and 한국어.

Model Context Protocol (MCP) has become the standard way for AI agents to use external tools. But there is a tension at its core: agents need many tools to do useful work, yet every tool added fills the model’s context window, leaving less room for the actual task.

Code Mode is a technique we first introduced for reducing context window usage during agent tool use. Instead of describing every operation as a separate tool, let the model write code against a typed SDK and execute the code safely in a Dynamic Worker Loader. The code acts as a compact plan. The model can explore tool operations, compose multiple calls, and return just the data it needs. Anthropic independently explored the same pattern in their Code Execution with MCP post.

Today we are introducing a new MCP server for the entire Cloudflare API — from DNS and Zero Trust to Workers and R2 — that uses Code Mode. With just two tools, search() and execute(), the server is able to provide access to the entire Cloudflare API over MCP, while consuming only around 1,000 tokens. The footprint stays fixed, no matter how many API endpoints exist.

For a large API like the Cloudflare API, Code Mode reduces the number of input tokens used by 99.9%. An equivalent MCP server without Code Mode would consume 1.17 million tokens — more than the entire context window of the most advanced foundation models.

Code mode savings vs native MCP, measured with tiktoken

You can start using this new Cloudflare MCP server today. And we are also open-sourcing a new Code Mode SDK in the Cloudflare Agents SDK, so you can use the same approach in your own MCP servers and AI Agents.

Server‑side Code Mode

This new MCP server applies Code Mode server-side. Instead of thousands of tools, the server exports just two: search() and execute(). Both are powered by Code Mode. Here is the full tool surface area that gets loaded into the model context:

`[ { “name”: “search”, “description”: “Search the Cloudflare OpenAPI spec. All $refs are pre-resolved inline.”, “inputSchema”: { “type”: “object”, “properties”: { “code”: { “type”: “string”, “description”: “JavaScript async arrow function to search the OpenAPI spec” } }, “require

d”: [“code”] } }, { “name”: “execute”, “description”: “Execute JavaScript code against the Cloudflare API.”, “inputSchema”: { “type”: “object”, “properties”: { “code”: { “type”: “string”, “description”: “JavaScript async arrow function to execute” } }, “required”: [“code”] } } ]`

To discover what it can do, the agent calls search(). It writes JavaScript against a typed representation of the OpenAPI spec. The agent can filter endpoints by product, path, tags, or any other metadata and narrow thousands of endpoints to the handful it needs. The full OpenAP

I spec never enters the model context. The agent only interacts with it through code.

When the agent is ready to act, it calls execute(). The agent writes code that can make Cloudflare API requests, handle pagination, check responses, and chain operations together in a single execution.

Both tools run the generated code inside a Dynamic Worker isolate — a lightweight V8 sandbox with no file system, no environment variables to leak through prompt injection and external fetches disabled by default. Outbound requests can be explicitly controlled with outbound fetch handlers when needed.

Example: Protecting an origin from DDoS attacks

Suppose a user tells their agent: “protect my origin from DDoS attacks.” The agent’s first step is to consult documentation. It might call the Cloudflare Docs MCP Server, use a Cloudflare Skill, or search the web directly. From the docs it learns: put Cloudflare WAF and DDoS protection rules in front of the origin.

Step 1: Search for the right endpointsThe search tool gives the model a spec object: the full Cloudflare OpenAPI spec with all $refs pre-resolved. The model writes JavaScript against it. Here the agent looks for WAF and ruleset endpoints on a zone:

async () => { const results = []; for (const [path, methods] of Object.entries(spec.paths)) { if (path.includes('/zones/') && (path.includes('firewall/waf') || path.includes('rulesets'))) { for (const [method, op] of Object.entries(methods)) { results.push({ method: method.toUpperCase(), path, summary: op.summary }); } return results; }

The server runs this code in a Workers isolate and returns:

`[ { “method”: “GET”, “path”: “/zones/{zone_id}/firewall/waf/packages”, “summary”: “List WAF packages” }, { “method”: “PATCH”, “path”: “/zones/{zone_id}/firewall/waf/packages/{package_id}”, “summary”: “Update a WAF package” }, { “method”: “GET”, “path”: “/zones/{zone_id}/firewall

/waf/packages/{package_id}/rules”, “summary”: “List WAF rules” }, { “method”: “PATCH”, “path”: “/zones/{zone_id}/firewall/waf/packages/{package_id}/rules/{rule_id}”, “summary”: “Update a WAF rule” }, { “method”: “GET”, “path”: “/zones/{zone_id}/rulesets”, “summary”: “List zone ru

lesets” }, { “method”: “POST”, “path”: “/zones/{zone_id}/rulesets”, “summary”: “Create a zone ruleset” }, { “method”: “GET”, “path”: “/zones/{zone_id}/rulesets/phases/{ruleset_phase}/entrypoint”, “summary”: “Get a zone entry point ruleset” }, { “method”: “PUT”, “path”: “/zones/{z

one_id}/rulesets/phases/{ruleset_phase}/entrypoint”, “summary”: “Update a zone entry point ruleset” }, { “method”: “POST”, “path”: “/zones/{zone_id}/rulesets/{ruleset_id}/rules”, “summary”: “Create a zone ruleset rule” }, { “method”: “PATCH”, “path”: “/zones/{zone_id}/rulesets/{r

uleset_id}/rules/{rule_id}”, “summary”: “Update a zone ruleset rule” } ]`

The full Cloudflare API spec has over 2,500 endpoints. The model narrowed that to the WAF and ruleset endpoints it needs, without any of the spec entering the context window.

The model can also drill into a specific endpoint’s schema before calling it. Here it inspects what phases are available on zone rulesets:

`async () => { const op = spec.paths[‘/zones/{zone_id}/rulesets’]?.get; const items = op?.responses?.[‘200’]?.content?.[‘application/json’]?.schema; // Walk the schema to find the phase enum const props = items?.allOf?.[1]?.properties?.result?.items?.allOf?.[1]?.properties; return { phases: props?.phase?.enum }; }

{ “phases”: [ “ddos_l4”, “ddos_l7”, “http_request_firewall_custom”, “http_request_firewall_managed”, “http_response_firewall_managed”, “http_ratelimit”, “http_request_redirect”, “http_request_transform”, “magic_transit”, “magic_transit_managed” ] } `

The agent now knows the exact phases it needs: ddos_l7 for DDoS protection and http_request_firewall_managed for WAF.

Step 2: Act on the API The agent switches to using execute. The sandbox gets a cloudflare.request() client that can make authenticated calls to the Cloudflare API. First the agent checks what rulesets already exist on the zone:

`` async () => { const response = await cloudflare.request({ method: “GET”, path: /zones/${zoneId}/rulesets }); return response.result.map(rs => ({ name: rs.name, phase: rs.phase, kind: rs.kind }));

} [ { “name”: “DDoS L7”, “phase”: “ddos_l7”, “kind”: “managed” }, { “name”: “Cloudflare Managed”,”phase”: “http_request_firewall_managed”, “kind”: “managed” }, { “name”: “Custom rules”, “phase”: “http_request_firewall_custom”, “kind”: “zone” } ] ``

The agent sees that managed DDoS and WAF rulesets already exist. It can now chain calls to inspect their rules and update sensitivity levels in a single execution:

`` async () => { // Get the current DDoS L7 entrypoint ruleset const ddos = await cloudflare.request({ method: “GET”, path: /zones/${zoneId}/rulesets/phases/ddos_l7/entrypoint });

// Get the WAF managed ruleset const waf = await cloudflare.request({ method: “GET”, path: /zones/${zoneId}/rulesets/phases/http_request_firewall_managed/entrypoint }); } ``

This entire operation, from searching the spec and inspecting a schema to listing rulesets and fetching DDoS and WAF configurations, took four tool calls.

The Cloudflare MCP server

We started with MCP servers for individual products. Want an agent that manages DNS? Add the DNS MCP server. Want Workers logs? Add the Workers Observability MCP server. Each server exported a fixed set of tools that mapped to API operations. This worked when the tool set was small, but the Cloudflare API has over 2,500 endpoints. No collection of hand-maintained servers could keep up.

The Cloudflare MCP server simplifies this. Two tools, roughly 1,000 tokens, and coverage of every endpoint in the API. When we add new products, the same search() and execute() code paths discover and call them — no new tool definitions, no new MCP servers. It even has support for the GraphQL Analytics API.

Our MCP server is built on the latest MCP specifications. It is OAuth 2.1 compliant, using Workers OAuth Provider to downscope the token to selected permissions approved by the user when connecting. The agent only gets the capabilities the user explicitly granted.

Comparing approaches to context reduction

Several approaches have emerged to reduce how many tokens MCP tools consume:

Client-side Code Mode was our first experiment. The model writes TypeScript against typed SDKs and runs it in a Dynamic Worker Loader on the client. The tradeoff is that it requires the agent to ship with secure sandbox access. Code Mode is implemented in Goose and Anthropics

Claude SDK as Programmatic Tool Calling.

Command-line interfaces are another path. CLIs are self-documenting and reveal capabilities as the agent explores. Tools like OpenClaw and Moltworker convert MCP servers into CLIs using MCPorter to give agents progressive disclosure. The limitation is obvious: the agent needs

a shell, which not every environment provides and which introduces a much broader attack surface than a sandboxed isolate.

Dynamic tool search surfaces a smaller set of tools hopefully relevant to the current task. It shrinks context use but now requires a search function that must be maintained and evaluated, and each matched tool still uses tokens.

Each approach solves a real problem. But for MCP servers specifically, server-side Code Mode combines their strengths: fixed token cost regardless of API size, no modifications needed on the agent side, progressive discovery built in, and safe execution inside a sandboxed isolate

. The agent just calls two tools with code. Everything else happens on the server.

More information on different MCP setup configurations can be found at the Cloudflare MCP repository.

Looking forward

Code Mode solves context costs for a single API. But agents rarely talk to one service. A developer’s agent might need the Cloudflare API alongside GitHub, a database, and an internal docs server. Each additional MCP server brings the same context window pressure we started with.

Cloudflare MCP Server Portals let you compose multiple MCP servers behind a single gateway with unified auth and access control. Cloudflare is building a first-class Code Mode integration for MCP servers, exposing them to agents with built-in progressive discovery and the same fi

xed-token footprint.

Cloudflare One is the first SASE offering modern post-quantum encryption across the full platform

2026-02-23

This post is also available in Português and Español (Latinoamérica).

During Security Week 2025, we launched the industry’s first cloud-native post-quantum Secure Web Gateway (SWG) and Zero Trust solution, a major step towards securing enterprise network traffic sent from end user devices to public and private networks.

But this is only part of the equation. To truly secure the future of enterprise networking, you need a complete Secure Access Service Edge (SASE).

Today, we complete the equation: Cloudflare One is the first SASE platform to support modern standards-compliant post-quantum (PQ) encryption in our Secure Web Gateway, and across Zero Trust and Wide Area Network (WAN) use cases. More specifically, Cloudflare One now offers post-

quantum hybrid ML-KEM (Module-Lattice-based Key-Encapsulation Mechanism) across all major on-ramps and off-ramps.

To complete the equation, we added support for post-quantum encryption to our Cloudflare IPsec (our cloud-native WAN-as-a-Service) and Cloudflare One Appliance (our physical or virtual WAN appliance that establish Cloudflare IPsec connections). Cloudflare IPsec uses the IPsec protocol to establish encrypted tunnels from a customer’s network to Cloudflare’s global network, while IP Anycast is used to automatically route that tunnel to the nearest Cloudflare data center. Cloudflare IPsec simplifies configuration and provides high availability; if a specific data center becomes unavailable, traffic is automatically rerouted to the closest healthy data center. Cloudflare IPsec runs at the scale of our global network, and supports site-to-site across a WAN as well as outbound connections to the Internet.

The Cloudflare One Appliance upgrade is generally available as of appliance version 2026.2.0. The Cloudflare IPsec upgrade is in closed beta, and you can request access by adding your name to our closed beta list.

Post-quantum cryptography matters now

Quantum threats are not a “next decade” problem. Here is why our customers are prioritizing post-quantum cryptography (PQC) today:

The deadline is approaching. At the end of 2024, the National Institute of Standards and Technology (NIST) sent a clear signal (that has been echoed by other agencies): the era of classical public-key cryptography is coming to an end. NIST set a 2030 deadline for depreciating RSA and Elliptic Curve Cryptography (ECC) and transitioning to PQC that cannot be broken by powerful quantum computers. Organizations that haven’t begun their migration risk being out of compliance and vulnerable as the deadline nears.

Upgrades have historically been tricky. While 2030 might seem far away, upgrading cryptographic algorithms is notoriously difficult. History has shown us that depreciating cryptography can take decades: we found examples of MD5 causing problems 20 years after it was deprecated. This lack of crypto agility — the ability to easily swap out cryptographic algorithms — is a major bottleneck. By integrating PQ encryption directly into Cloudflare One, our SASE platform, we provide built-in crypto agility, simplifying how organizations offer remote access and site-to-site connectivity.

Data may already be at risk. Finally, “Harvest Now, Decrypt Later” is a present and persistent threat, where attackers harvest sensitive network traffic today and then store it until quantum computers become powerful enough to decrypt it. If your data has a shelf life of more

than a few years (e.g. financial information, health data, state secrets) it is already at risk unless it is protected by PQ encryption.

The two migrations on the road to quantum safety: key agreement and digital signatures

Transitioning network traffic to post-quantum cryptography (PQC) requires an overhaul of two cryptographic primitives: key agreement and digital signatures.

Migration 1: Key establishment. Key agreement allows two parties to establish a shared secret over an insecure channel; the shared secret is then used to encrypt network traffic, resulting in post-quantum encryption. The industry has largely converged on ML-KEM (Module-Lattic

e-based Key-Encapsulation Mechanism) as the standard PQ key agreement protocol.

ML-KEM has been widely adopted for use in TLS, usually deployed alongside classical Elliptic Curve Diffie Hellman (ECDHE), where the key used to encrypt network traffic is derived by mixing the outputs of the ML-KEM and ECDHE key agreements. (This is also known as “hybrid ML-KEM”). Well over 60% of human-generated TLS traffic to Cloudflare’s network is currently protected with hybrid ML-KEM. The transition to hybrid ML-KEM has been successful because it:

Because ML-KEM runs in parallel with classical ECDHE, there is no reduction in security and compliance as compared to the classical ECDHE approach.

Migration 2: Digital signatures. Meanwhile, digital signatures and certificates protect authenticity, stopping active adversaries from impersonating the server to the client. Unfortunately, PQ signatures are currently larger in size than classical ECC algorithms, which has sl

owed their adoption. Fortunately, the migration to PQ signatures is less urgent, because PQ signatures are designed to stop active adversaries armed with powerful quantum computers, which are not known to exist yet. Thus, while Cloudflare is actively contributing to the standardi

zation and rollout of PQ digital signatures, the current Cloudflare IPsec upgrade focuses on upgrading key establishment to hybrid ML-KEM.

The U.S. Cybersecurity & Infrastructure Security Agency (CISA) recognized the nature of these two migrations in its January 2026 publication, “Product Categories for Technologies That Use Post-Quantum Cryptography Standards.”

Breaking new ground with IPsec

To achieve a SASE fully protected with post-quantum encryption, we’ve upgraded our Cloudflare IPsec products to support hybrid ML-KEM in the IPsec protocol.

Post-quantum cryptography matters now

The deadline is approaching. At the end of 2024, the National Institute of Standards and Technology (NIST) sent a clear signal (that has been echoed by other agencies): the era of classical public-key cryptography is coming to an end. NIST set a 2030 deadline for depreciating RSA and Elliptic Curve Cryptography (ECC) and transitioning to PQC that cannot be broken by powerful quantum computers. Organizations that haven’t begun their migration risk being out of compliance and vulnerable as the deadline nears.

The two migrations on the road to quantum safety: key agreement and digital signatures

Breaking new ground with IPsec

The Internet Key Exchange (IKE) protocol for IPsec (IKEv2) is designed to be extensible to new cryptographic algorithms. Because of this, we were able to add support for hybrid ML-KEM by extending IKEv2, rather than by designing a new key exchange protocol. Our IKEv2 extension im

plements the ML-KEM (kyber768) algorithm in combination with the classical Elliptic Curve Diffie Hellman (ECDHE) protocol using curve P-384. IPsec will use the combined output of both key exchange algorithms to derive the shared secrets that protect network traffic. We based our

IKEv2 extension on the latest IETF drafts, RFC 9308 (which describes the hybrid method of combining a classical and a quantum-safe KEM) and draft-ietf-ipsecme-hybrid-auth-init-ikev2 (which details how hybrid key exchange can be applied to IKEv2).

The upgrade is implemented in Cloudflare’s Border Gateway Protocol (BGP) stack, and runs on a dedicated set of hardware and software. Both the Cloudflare One Appliance and Cloudflare IPsec (site-to-site) use this updated stack.

Cloudflare is a member of the Quantum-Safe Hybrid Internet (QuSHI) project (funded by the German Federal Ministry of Education and Research) and is actively contributing to the standardization of hybrid cryptography in IETF and other standards bodies. Our hybrid ML-KEM for IPsec

is the result of that active contribution.

Get started today

Cloudflare IPsec customers can add their names to our closed beta list to begin testing our hybrid ML-KEM IPsec offering. The Cloudflare One Appliance upgrade is generally available as of appliance version 2026.2.0.

Cloudflare’s connectivity cloud protects entire corporate networks, helps customers build Internet-scale applications efficiently, accelerates any website or Internet application, wards off DDoS attacks, keeps hackers at bay, and can help you on your journey to Zero Trust.

How we rebuilt Next.js with AI in one week

2026-02-24

6 min read

Editor’s note: This post is the second of a two-part series detailing how we used AI to build vinext, a drop-in replacement for Next.js based on Vite. You can find part one here.

Last week, my team at Cloudflare used AI to rebuild Next.js on Vite in a single week. The result is vinext, a drop-in replacement that builds up to 4x faster, produces 57% smaller bundles, and deploys to Cloudflare Workers with a single command. You can try it out today by running npm create vinext@latest.

This isn’t just a fun AI experiment. It’s a look at how AI will transform the way we build software.

From zero to production in one week

The entire process, from ideation to launch, took just one week. Here’s a breakdown:

  • Day 1-2: Research and architecture. We used AI to explore existing solutions, evaluate trade-offs, and design a high-level architecture. The goal was to create a Next.js-compatible API on top of Vite.
  • Day 3-5: Code generation and iteration. AI generated the initial codebase, which we then iteratively refined using a combination of AI-assisted refactoring and manual adjustments. The key was a strong test suite that allowed us to quickly validate changes.
  • Day 6-7: Testing and deployment. We leveraged AI to generate additional tests, identify performance bottlenecks, and optimize the deployment process. The result was a robust, performant application that could be deployed with a single command.

The speed and efficiency of this process were astounding. AI didn’t just write code; it helped us explore design spaces, identify potential issues, and optimize every step of the development lifecycle.

How we did it: AI-driven development

Our approach was built around three core principles:

  1. Clear specifications. We started with a clear, unambiguous specification of the Next.js API. This allowed AI to generate accurate and consistent code.
  2. Strong test suite. A comprehensive test suite was crucial for validating the generated code and catching regressions early. We used AI to generate a significant portion of our tests, which saved us a lot of time.
  3. Iterative refinement. We didn’t expect AI to get everything right on the first try. Instead, we treated the generated code as a starting point, iteratively refining it with AI-assisted refactoring and manual adjustments.

This approach allowed us to leverage AI’s strengths—speed and code generation—while mitigating its weaknesses—lack of common sense and potential for errors.

The results: faster builds, smaller bundles, easier deployments

Vinext delivers significant improvements over traditional Next.js:

  • Up to 4x faster builds. By leveraging Vite’s lightning-fast development server and optimized build process, vinext dramatically reduces build times.
  • 57% smaller bundles. Vinext’s optimized bundle size leads to faster load times and improved performance.
  • Single-command deployments to Cloudflare Workers. Vinext seamlessly integrates with Cloudflare Workers, allowing you to deploy your application to the edge with a single command.

These improvements translate to a better developer experience, faster iteration cycles, and a more performant application for your users.

Looking forward: the future of AI-driven development

Our experiment with vinext has convinced us that AI-driven development is the future of software engineering. It’s not about replacing developers with AI; it’s about empowering developers with AI to build better software, faster.

We’re excited to see how vinext evolves and how AI continues to transform the way we build software.

6) Microsoft and OpenAI joint statement on continuing partnership（Microsoft）

来源： https://blogs.microsoft.com/blog/2026/02/27/microsoft-and-openai-joint-statement-on-continuing-partnership/

原文

Since 2019, Microsoft and OpenAI have worked together to advance artificial intelligence responsibly and make its benefits broadly accessible. What began as a research partnership has grown into one of the most consequential collaborations in technology — grounded in mutual trust

, deep technical integration, and a long‑term commitment to innovation.

As conversations around AI investments and partnerships grow and as OAI announces new funding and new partners as they did today, we want to ensure these announcements are understood within the existing construct of our partnership. Nothing about today’s announcements in any way changes the terms of the Microsoft and OpenAI relationship that have been previously shared in our joint blog in October 2025.

The partnership remains strong and central. Microsoft and OpenAI continue to work closely across research, engineering, and product development, building on years of deep collaboration and shared success.

Our IP relationship continues unchanged. Microsoft maintains its exclusive license and access to intellectual property across OpenAI models and products. Collaborations like the partnership between OpenAI and Amazon were always contemplated under our agreements and Microsoft is e

xcited to see what they build together.

Our commercial and revenue share relationship remains unchanged. The ongoing revenue share arrangement remains unchanged and has always included sharing revenue from partnerships between OpenAI and other cloud providers.

Azure remains the exclusive cloud provider of stateless OpenAI APIs. Microsoft is the exclusive cloud provider for stateless APIs that provide access to OpenAI’s models and IP. These APIs can be purchased from Microsoft or directly from OpenAI. Customers and developers benefit fr

om Azure’s global infrastructure, security, and enterprise-grade capabilities at scale. Any stateless API calls to OpenAI models that result from a collaboration between OpenAI and any third party – including Amazon – would be hosted on Azure.

OpenAI’s first party products, including Frontier, will continue to be hosted on Azure.

AGI definition and processes are unchanged. The contractual definition of AGI and the process for determining if it has been achieved remains the same.\n\nThe partnership supports OpenAI’s growth. As OpenAI scales, it continues to have flexibility to commit to additional compute

elsewhere, including through large-scale infrastructure initiatives such as the Stargate project.

The partnership was designed to give Microsoft and OpenAI room to pursue new opportunities independently, while continuing to collaborate, which each company is doing, together and independently.

We remain committed to our partnership and to the shared mission that brought us together. We continue to work side‑by‑side to deliver powerful AI tools, advance responsible development, and ensure that AI benefits people and organizations everywhere.

Principal Product Manager

This month’s Visual Studio update continues our focus on helping you move faster and stay in flow, with practical improvements across AI assistance, debugging, testing, and modernization. Building on the momentum from January’s editor updates, the February release brings smarter

diagnostics and targeted support for real world development scenarios, from WinForms maintenance to C++ modernization.

All of the features highlighted are available in the Visual Studio 2026 Stable Channel as part of the February 2026 feature update (18.3). Please update to the latest version to try out these new features!

WinForms Expert Agent

The WinForms Expert agent provides a focused guide for handling key challenges in WinForms development. It covers several important areas: Designer vs. regular code: Understand which C# features apply to designer-generated code and business logic.

  • Modern .NET patterns: Updated for .NET 8-10, including MVVM with Community Toolkit, async/await with proper InvokeAsync overloads, Dark mode with high-DPI support, and nullable reference types.

  • Layout: Advice on using TableLayoutPanel and FlowLayoutPanel for responsive, cross-device design.

  • CodeDOM serialization: Rules for property serialization and avoiding common issues with [DefaultValue] and ShouldSerialize*() methods.

  • Exception handling: Patterns for async event handlers and robust application-level error handling.

The agent serves as an expert reviewer for your WinForms code, providing comprehensive guidance on everything from naming controls to ensuring accessibility. The WinForms Agent is automatically implemented and included in the system prompt when necessary.

Smarter Test Generation with GitHub Copilot

Visual Studio now includes intelligent test generation with GitHub Copilot, making it faster to create and refine unit tests for your C# code. This purpose-built workflow works seamlessly with xUnit, NUnit, and MSTest.

https://devblogs.microsoft.com/visualstudio/wp-content/uploads/sites/4/2026/02/prompt-image-intro.webp

Simply type @Test in GitHub Copilot Chat, describe what you want to test, and Copilot generates the test code for you. Whether you’re starting fresh or improving coverage on existing projects, this feature helps you write tests faster without leaving your workflow.

Slash Commands for Custom Prompts

Invoke your favorite custom prompts faster using slash commands in Copilot Chat. Type / and your custom prompts appear at the top of the list, marked with a bookmark icon for easy identification.

https://devblogs.microsoft.com/visualstudio/wp-content/uploads/sites/4/2026/02/slash-commands.webp

We’ve also added two additional commands:

– /generateInstructions: Automatically generate a copilot-instructions.md file for your repository using project context like coding style and preferences

– /savePrompt: Extract a reusable prompt from your current chat thread and save it for later use via / commands

These shortcuts make it easier to build and reuse your workflow patterns.

C++ App Modernization

GitHub Copilot app modernization for C++ is now available in Public Preview. GitHub Copilot app modernization for C++ helps you update your C++ projects to use the latest versions of MSVC and to resolve upgrade-related issues. You can find our user documentation on Microsoft Learn.

https://devblogs.microsoft.com/visualstudio/wp-content/uploads/sites/4/2026/02/assesment-markdown.webp

DataTips in IEnumerable Visualizer

You can now use DataTips in the IEnumerable Visualizer while debugging. Just hover over any cell in the grid to see the full object behind that value, the same DataTip experience you’re used to in the editor or Watch window.

When you hover over a cell, a DataTip shows all the object’s properties in one place. This makes it much easier to debug collections with complex or nested data. Whether it’s a List of objects or a dictionary with structured values, one hover lets you quickly inspect everythin

g inside.

https://devblogs.microsoft.com/visualstudio/wp-content/uploads/sites/4/2026/02/IEnumerableVisualizer.webp

Analyze Call Stack with Copilot

You can now Analyze Call Stack with Copilot to help you quickly understand what your app is doing when debugging stops. When you pause execution, you can select Analyze with Copilot in the Call Stack window. Copilot reviews the current stack and explains why the app isn’t progres

sing whether the thread is waiting on work, looping, or blocked by something.

This makes the call stack more than just a list of frames. It becomes a helpful guide that shows what’s happening in your app so you can move faster toward the real fix.

https://devblogs.microsoft.com/visualstudio/wp-content/uploads/sites/4/2026/02/callstackanalysis.mp4

Profiler agent with Unit Test support

The Profiler Agent (@profiler) now works with unit tests. You can use your existing tests to check performance improvements, making it easier to measure and optimize your code in more situations. The agent can discovers relevant unit tests/BenchmarkDotNet benchmarks that exercise

performance-critical code paths.

If no good tests or benchmarks are available, it automatically creates a small measurement setup so you can capture a baseline and compare results after changes. This unit-test-focused approach also makes the Profiler Agent useful for C++ projects, where benchmarks aren’t always

practical, but unit tests often already exist.

https://devblogs.microsoft.com/visualstudio/wp-content/uploads/sites/4/2026/02/copilot-profiler-chat-1.webp

Faster and More Reliable Razor Hot Reload

Hot Reload for Razor files are now faster and more reliable. By hosting the Razor compiler inside the Roslyn process, edits to .razor files apply more quickly and avoid delays that previously slowed Blazor workflows. We also reduced the number of blocked edits, with more changes

now applying without requiring a rebuild, including file renames and several previously unsupported code edits. When a rebuild is still required, Hot Reload can now automatically restart the app instead of ending the debug session, helping you stay in flow.

We are continuing to invest in features that help you understand, test, and improve existing code, not just write new code. Try these updates in the Visual Studio 2026 Stable Channel and let us know what is working well and where we can improve. Your feedback directly shapes what we build next.

8) Public Google API keys can be used to expose Gemini AI data（Malwarebytes / Truffle Security）

来源： https://www.malwarebytes.com/blog/news/2026/02/public-google-api-keys-can-be-used-to-expose-gemini-ai-data

原文

Google Maps/Cloud API (Application Programming Interface) keys that used to be safe to publish can now, in many cases, be used as real Gemini AI credentials. This means that any key sitting in public JavaScript or application code may now let attackers connect to Gemini through i

ts API, access data, or run up someone else’s bill.

Researchers found around 2,800 live Google API keys in public code that can authenticate to Gemini, including keys belonging to major financial, security, recruiting firms, and even Google itself.

Historically, Google Cloud API keys for services like Maps, YouTube embeds, Firebase, etc., were treated as non‑secret billing identifiers, and Google’s own guidance allowed embedding them in client‑side code.

If we compare this issue to reusing your password across different sites and platforms, we see that using a single identifier can become a skeleton key to more valuable assets than users or developers ever intended.

The key difference is where responsibility sits. With password reuse, end users are explicitly warned. Every service tells them to pick unique passwords, and the security community has hammered this message for years. If the same password is reused across three sites and one brea

ch compromises all of them, the risk comes from a user decision, even if convenience drove that decision.

With Google API keys, developers and security teams were following Google’s own historical guidance that these keys were just billing identifiers safe for client‑side exposure. When Gemini was turned on, those old API keys suddenly worked as real authentication credentials.

From an attacker’s perspective, password reuse means you can take one credential stolen from a weak site and replay it against email, banking, or cloud accounts using credential stuffing. The Gemini change means a key originally scoped in everyone’s mental model as “just for Maps

” now works against an AI endpoint that may be wired into documents, calendars, or other sensitive workflows. It can also be abused to burn through someone’s cloud budget at scale.

How to stay safe

The difference with this instance of what is effectively password reuse is that this time it’s been effectively baked in by design rather than chosen by users.

The core problem is that Google uses a single API key format for two fundamentally different purposes: public identification and sensitive authentication. The Gemini API inherited a key management architecture built for a different purpose.

The researchers say Google has recognized the problem they reported and took meaningful steps, but have yet to fix the root cause.

Advice for developers

Developers should check whether Gemini (Generative Language API) is enabled on their projects and audit all API keys in their environment to determine if any are publicly exposed and rotate them immediately.

  • Check every Google Cloud Platform (GC project for the Generative Language API. Go to the GCP console, navigate to APIs & Services > Enabled APIs & Services, and look for the Generative Language API. Do this for every project in your organization. If it’s not enabled, you’re not affected by this specific issue.

  • If the Generative Language API is enabled, audit your API keys. Navigate to APIs & Services > Credentials. Check each API key’s configuration. You’re looking for two types of keys:Keys showing a warning icon, meaning they are set to unrestricted

  • Keys that explicitly list the Generative Language API in their allowed services

Either configuration allows the key to access Gemini.

  • Verify that none of those keys are public. This is the critical step. If you find a key with Gemini access embedded in client-side JavaScript, checked into a public repository, or otherwise exposed online, you have a problem. Start with your oldest keys first. Those are the most likely to have been deployed publicly under the old guidance that API keys are safe to share, and then retroactively gained Gemini privileges when someone on your team enabled the API. If you find an exposed key, rotate it.

Advice for individuals

For regular users, this is less about key management and more about keeping your Google account locked down and being cautious about third-party access.

  • Only link Gemini to accounts or data stores (Drive, Mail, Calendar, enterprise systems) you’re comfortable being reachable via API and regularly review which integrations and third‑party apps have access to your Google account.

  • When evaluating apps that integrate Gemini (browser extensions, SaaS tools, mobile apps), favour those that make Gemini calls from their backend rather than directly from your browser.

  • If you use Gemini via a Google Cloud project (e.g., you’re a power user or use it for work), monitor GCP billing reports and usage logs for unusual Gemini activity, especially spikes that do not match your own usage.

9) Introducing the Official ClickHouse Kubernetes Operator（ClickHouse）

来源： https://clickhouse.com/blog/clickhouse-kubernetes-operator

原文

At ClickHouse, our mission has always been to make real-time analytics accessible and lightning-fast. As more of our community moves toward cloud-native architectures, the need for a robust, automated way to manage Open Source ClickHouse distribution on Kubernetes has become clea

r.

Today, we are thrilled to announce the release of the Official ClickHouse Kubernetes Operator - available now, open-source (under Apache-2.0 licence), and free for everyone.

Running a stateful, high-performance database like ClickHouse on Kubernetes presents unique challenges: horizontal and vertical scaling, ensuring data persistence during pod restarts, and executing seamless upgrades.

The ClickHouse Operator simplifies these tasks by extending the Kubernetes API. It allows you to manage complex ClickHouse clusters using convenient Custom Resource Definitions (CRDs). Instead of manually configuring Pods and Services, you simply describe your desired state, and

the Operator handles the rest.

  • Automated Cluster Provisioning: Deploy a production-ready, multi-node cluster with sharding and replication in minutes.

  • ClickHouse Keeper Support: Deploy and manage ClickHouse Keeper.

  • Vertical & Horizontal Scaling: Easily adjust CPU / Memory resources or add new shards to your cluster with minimal downtime.

  • Configuration Management: Safely update your configuration and ClickHouse version in a single manifest change. The Operator manages the sequence, ensuring that new configuration parameters are rolled out only to updated pods, eliminating the risk of service disruptions caused by version-config mismatches.

  • Seamless Upgrades: Perform rolling updates to new ClickHouse versions without dropping queries.

When implementing the operator, we wanted to reuse the ClickHouse Cloud production experience and build on bulletproof, reliable features. That’s why we:

  • We rely on ClickHouse Keeper for coordination — it’s built in, so you don’t need to run ZooKeeper separately, and there’s no “Keeper-less” mode to worry about. This post covers the benefits.

  • Make the Replicated a default database engine. DatabaseReplicated has been powering ClickHouse Cloud since the beginning of our business and has proved its reliability and convenience. That’s why it was an obvious choice for us to use it in the Operator as well. It eliminates the need to write the ON CLUSTER clause in every DDL query you issue to the database.

  • Have a StatefulSet per replica. This key decision allows us to implement different upgrade strategies and have fine-grained control over each replica (e.g., the version they run, their configuration, etc.).

  • TLS/SSL encryption for ClickHouse Keeper and Client ClickHouse communication.

  • Configuration overrides for both ClickHouse and Keeper.

In general, our key principle is keeping things simple. If something can be implemented on the ClickHouse side in C++, it has to be there. That made the Operator a very thin layer on top of what ClickHouse already can do.

Getting up and running is as simple as applying a few YAML files.

  1. Install the cert-manager

The operator uses defaulting and validating webhooks to ensure the validity of Custom Resource (CR) objects. It requires cert-manager to issue a certificate.

1# Using kubectl 2kubectl apply -f https://github.com/cert-manager/cert-manager/releases/download/v1.19.2/cert-manager.yaml

1# Or using helmchart 2helm install cert-manager –create-namespace –namespace cert-manager oci://quay.io/jetstack/charts/cert-manager –set crds.enabled=true –version v1.19.2

  1. Install the Operator

1# Using kubectl 2kubectl apply -f https://github.com/ClickHouse/clickhouse-operator/releases/download/latest/clickhouse-operator.yaml

1# Or our helmchart 2helm install clickhouse-operator –create-namespace -n clickhouse-operator-system oci://ghcr.io/clickhouse/clickhouse-operator-helm

  1. Deploy a Simple Cluster Below is a basic example of a Custom Resource (CR) to deploy a two-node cluster:

YAML CR

1apiVersion: clickhouse.com/v1alpha1 2kind: KeeperCluster 3metadata: 4 name: sample 5spec: 6 replicas: 3 7 dataVolumeClaimSpec: 8 accessModes: 9 - ReadWriteOnce 10 resources: 11 requests: 12 storage: 10Gi 13— 14apiVersion: clickhouse.com/v1alpha1 15kind: ClickHouseCluster 16metadata: 17 name: sample 18spec: 19 replicas: 2 20 dataVolumeClaimSpec: 21 accessModes: 22 - ReadWriteOnce 23 resources: 24 requests: 25 storage: 10Gi 26 keeperClusterRef: 27 name: sample

We believe that the tools used to manage ClickHouse should be as open as the database itself. This Operator is free to use. We invite the community to contribute, report bugs, and help us shape the roadmap for cloud-native ClickHouse.

We’d love to hear your feedback!

Happy scaling!
