As I listened to your warm voice and the background music I found myself waiting for you to say Take a deep breath in and exhale.😅

New course: MCP: Build Rich-Context AI Apps with Anthropic. Learn to build AI apps that access tools, data, and prompts using the Model Context Protocol in this short course, created in partnership with Anthropic Anthropic and taught by Elie Schoppik Elie Schoppik, its Head of Technical Education. Connecting AI applications to external systems that bring rich context to LLM-based applications has often meant writing custom integrations for each use case. MCP is an open protocol that standardizes how LLMs access tools, data, and prompts from external sources, and simplifies how you provide context to your LLM-based applications. For example, you can provide context via third-party tools that let your LLM make API calls to search the web, access data from local docs, retrieve code from a GitHub repo, and so on. MCP, developed by Anthropic, is based on a client-server architecture that defines the communication details between an MCP client, hosted inside the AI application, and an MCP server that exposes tools, resources, and prompt templates. The server can be a subprocess launched by the client that runs locally or an independent process running remotely. In this hands-on course, you'll learn the core architecture behind MCP. You’ll create an MCP-compatible chatbot, build and deploy an MCP server, and connect the chatbot to your MCP server and other open-source servers. Here’s what you’ll do: - Understand why MCP makes AI development less fragmented and standardizes connections between AI applications and external data sources - Learn the core components of the client-server architecture of MCP and the underlying communication mechanism - Build a chatbot with custom tools for searching academic papers, and transform it into an MCP-compatible application - Build a local MCP server that exposes tools, resources, and prompt templates using FastMCP, and test it using MCP Inspector - Create an MCP client inside your chatbot to dynamically connect to your server - Connect your chatbot to reference servers built by Anthropic’s MCP team, such as filesystem, which implements filesystem operations, and fetch, which extracts contents from the web as markdown - Configure Claude Desktop to connect to your server and others, and explore how it abstracts away the low-level logic of MCP clients - Deploy your MCP server remotely and test it with the Inspector or other MCP-compatible applications - Learn about the roadmap for future MCP development, such as multi-agent architecture, MCP registry API, server discovery, authorization, and authentication MCP is an exciting and important technology that lets you build rich-context AI applications that connect to a growing ecosystem of MCP servers, with minimal integration work.

🚨 POC for CVE-2025-55182 that works on Next.js 16.0.6 Here are the exact, battle-tested queries you need — Censys, Shodan, FOFA, ZoomEye, Quake, BinaryEdge, and Nuclei matchers — all tuned specifically to find Next.js RSC / React Server Components instances vulnerable to CVE-2025-55182 (React2Shell). ⸻ ✅ 1. SHODAN QUERY (380K+ ASSETS) Find all servers leaking RSC Server Actions: Basic Query "Vary: RSC, Next-Router-State-Tree" More Aggressive Variant http.headers.vary:"RSC" AND http.headers.vary:"Next-Router-State-Tree" Superwide Coverage "Next-Router-State-Tree" OR "x-nextjs-cache" OR "server-actions" OR "__RSC__" Focused on Vulnerable Cache Indicators "x-nextjs-cache: HIT" "Next-Router-State-Tree" ⸻ ✅ 2. CENSYS QUERY (270K+ ASSETS) (match the screenshot you posted) Exact Censys Search services.http.response.headers.vary: "RSC, Next-Router-State-Tree" Safer Multi-Matcher services.http.response.headers.vary: "RSC" AND services.http.response.headers.vary: "Next-Router-State-Tree" Detect RSC Payload Exposure (critical) services.http.response.body: "__RSC__" Detect Flight Data Leaks services.http.response.body: "server-reference-manifest" ⸻ ✅ 3. FOFA QUERY (CHINA’S OSINT GIANT) (VERY POWERFUL for RSC/Next.js) Exact Header Based header="Next-Router-State-Tree" && header="RSC" Alternative (match screenshot patterns) "Next-Router-State-Tree" && "x-nextjs-cache" For massive result count body="__RSC__" || header="server-actions" ⸻ ✅ 4. ZOOMEYE QUERY ZoomEye scans often catch Node.js apps Shodan misses. Exact Unicode-Ready Query "Next-Router-State-Tree" && "RSC" Advanced app:"Next.js" && header:"RSC" ⸻ ✅ 5. QUAKE SEARCH (360K+ MATCHES) header:"Next-Router-State-Tree" AND header:"RSC" ⸻ ✅ 6. BINARYEDGE QUERY http.response.headers.vary:"Next-Router-State-Tree" ⸻ ✅ 7. QUERY headers:"Next-Router-State-Tree" && headers:"RSC" ⸻ 🎯 8. NUCLEI MATCHER (to detect RSC without scanning payloads) If you want a nuclei detector you can plug into your scanner: matchers: - type: word part: header words: - "RSC" - "Next-Router-State-Tree" - "server-actions" - "__RSC__" ⸻ 🚩 BONUS — THE MOST ADVANCED CROSS-ENGINE QUERY Use this when you want maximum global coverage: "Next-Router-State-Tree" OR "RSC" OR "__RSC__" OR "server-actions" OR "x-nextjs-cache" OR "Next-Server-Action" This identifies: •Next.js App Router •RSC endpoints •Server Actions •Flight data APIs •Pages exposing cache HITs (required for exploitation) •Systems likely vulnerable to CVE-2025-55182 (React2Shell)
