METATRON is an open-source, fully offline AI penetration testing assistant for Linux (Parrot OS / Debian). It orchestrates real recon and vuln-scanning tools — nmap, nikto, whois, dig, and more — feeds their output into a locally-hosted fine-tuned Qwen model via Ollama, and runs an agentic analysis loop to surface actionable findings. No data ever leaves your machine. The project is designed for security professionals who want AI-assisted analysis without shipping sensitive network topology or target data to a cloud API. After each recon phase, the model synthesizes results, chooses follow-up scans, and iterates until it has a complete picture. Final output is exported as a PDF or HTML report. Picking up nearly 400 GitHub stars within 48 hours of its April 2 release, METATRON taps into a real gap: AI copilots for pentesters that actually respect operational security. With Ollama handling local inference and no subscription required, the barrier to entry is just a GPU and a weekend.

qsag-core is a fresh open-source Python toolkit from Neoxyber that addresses the OWASP Top 10 for Agentic Applications 2026 — specifically the two fastest-growing attack vectors: MCP tool poisoning and prompt injection in AI agents. The library uses pattern-based detection (not ML-based, to minimize false positives) to scan 26 MCP tool poisoning patterns across 7 categories and detect 28+ prompt injection patterns across 9 threat categories. It also catches ghost agent attempts, credential harvesting, and memory poisoning in real time. The toolkit is available on PyPI, ships with cryptographic attestations, and is licensed under Apache 2.0. It was created in early April 2026, making it genuinely new-to-the-scene. The timing is significant: a recent Dark Reading poll found 48% of cybersecurity professionals now identify agentic AI as the #1 attack vector, up from a niche concern in 2025. Microsoft released a similar (but much larger-scope) Agent Governance Toolkit in early April, which validates the problem space but leaves room for nimble open-source tooling. qsag-core is early-stage — zero stars on GitHub as of today, minimal community traction, and no documented production deployments. But it addresses a problem that's going to become critical as MCP adoption accelerates. First-mover advantage in a niche that's about to explode.
Reviewer scorecard
“Finally a pentest assistant that doesn't phone home. The agentic loop between recon tools and the local Qwen model is genuinely clever — it actually chooses follow-up scans based on initial findings rather than just dumping raw output at you. Setup takes maybe 30 minutes if you have Ollama running.”
“I've been looking for exactly this since MCP started proliferating. Pattern-based detection over ML is the right call for security tooling — I can audit what it's flagging and why. Dropping this into my agent pipeline CI was a 30-minute job. The MCP tool poisoning scanner alone is worth it.”
“A fine-tuned Qwen running locally against nmap output isn't going to out-analyze a seasoned pentester. The model will hallucinate CVEs, miss context-dependent vulnerabilities, and produce reports that look authoritative but need heavy review. Useful as a research assistant, not a replacement for real expertise.”
“Zero stars, no known production deployments, no security audit of the security tool itself — that's an uncomfortable situation. Pattern-based detection will generate false positives as MCP tool definitions grow more complex, and attackers who know about this scanner can trivially evade it. Treat as research, not production security.”
“The real story here is the architecture: a local agent that uses real tools as its hands, with zero cloud dependency. As LLMs get better at reasoning about network state, this pattern — fully air-gapped AI operators — will become standard kit for any org that handles sensitive infrastructure.”
“MCP security is going to matter enormously as AI agents gain real-world tool access. The OWASP Top 10 for Agentic Applications is brand new and most teams haven't even read it. Getting familiar with these attack patterns now, before an incident forces the conversation, is table-stakes security hygiene.”
“The PDF/HTML report export is the sleeper feature here. For freelance pentesters who spend half their time formatting findings into deliverables, automated report generation alone justifies the install. Would love to see customizable report templates.”
“Unless you're running AI agents in production that use MCP tools, this is highly specialized developer/security tooling. Relevant context for understanding AI agent risks, but not something most creatives will interact with directly.”
