Free MCP for security AI: live BGP, DNS, threat graph

Hi HN! We just launched Codacy Guardrails, an IDE extension with a CLI for code analysis and MCP server that enforces security & quality rules on AI-generated code in real-time. It hooks into AI coding assistants (like VS Code Agent Mode, Cursor, Windsurf), silently scanning and fixing AI-suggested code that has vulnerabilities or violates your coding standards, while the code it’s being generated. We built this because coding agents can be a double-edged sword. They do boost productivity, but can easily introduce insecure or non-compliant code. One recent research team at NYU found that 40%…

I built an open-source AI agent for security testing to find and fix vulnerabilities in your code. I’ve noticed how bad security vulnerabilities have gotten with everyone shipping AI code slop, so I wanted to build something that allows for vibe-coding at full speed without compromising security. Traditional security tools aren’t effective, and manual pen-testing can’t keep up with the rapidly growing AI code This tool runs your code dynamically, finds vulnerabilities, and validates them through actual exploitation. You can either run it against your codebase or enter your (or someone…

I’m the developer behind the Web MCP at Bright Data. We just launched a free tier so any AI Engineer/ Vibe coder can give their LLM real web access — 5,000 requests/month at no cost. Unlike most MCP servers that wrap a single SaaS API (e.g. Gmail, GitHub), the Web MCP wraps the entire internet. It handles JS-heavy sites, auto-solves CAPTCHAs, and returns clean Markdown your model can use. Free tier includes: search_engine → search results from Google/Bing/Yandex scrape_as_markdown → fetch any URL as clean, LLM-friendly Markdown (with CAPTCHA handling) Quick start:…

Hi HN, I built CountermarkAI, a lightweight anti-scraping & bot-detection tool for content creators and website owners. It’s designed to help protect your work from unauthorized scraping and AI training, that repurposed your work without permission. How It Works: Use Hashtag – Creators add a unique hashtag to their content as a declaration of ownership. Protect Website – For those running your own sites, simply add a small snippet to your . The protect.js script works asynchronously by sending metadata from every page load back to our servers, logging requests, and flagging known AI-training…

AI agents now have impressive reasoning capabilities. This raises an important question: how dangerous are these AI agents at identifying & exploiting web vulnerabilities? We created CVE-bench to find out (I'm one contributor of 16). To our knowledge CVE-bench is the first benchmark using real-world web vulnerabilities to evaluate AI agents' cyberattack capabilities. We included 40 CVEs from NIST's database, focusing on critical-severity vulnerability (CVSS > 9.0). To properly evaluate agents’ attacks, we built isolated environments with containerization and identified 8 common attack…

Hey Hackernews! In the last few days I've dug up some work I was working on last year but never was able to ship due to perfectionism. But with my new attitude, here it is: I also immediately got it in MCP-form so you can use it in Claude and Cursor as well. Enable Claude / Cursor to know ANY API!! Video and links here: https://x.com/janwilmake/status/1903497808134496583 P.S. Expect bugs. Building in public. I've tested it with a few apis so far, and so far it worked really well as MCP every time. P.P.S. It's all Open source!…

ArgusAI ▲7AI firewall for LLM calls, MCP tools, and agentic workflows

We’re building an open-source tool that makes it easy to expose secure, LLM-optimized APIs on top of your structured data—without manually designing endpoints or worrying about compliance. AI agents and LLM-powered applications need structured access to data, but traditional APIs and databases weren’t built with AI workloads in mind. Our tool automatically generates APIs that: - Filter out PII & sensitive data to comply with GDPR, CPRA, SOC 2, and other regulations. - Provide traceability & auditing, so AI apps aren’t black boxes, and security teams stay in control. - Optimize for AI…
