I built Sixi AI to learn what it actually takes to red-team agentic AI in production. 46 autonomous attack agents execute 330+ techniques against any REST, MCP, A2A, or WebSocket endpoint — and every finding maps to EU AI Act articles, OWASP LLM Top 10, and MITRE ATLAS, shipping with the concrete patch that closes it.

What It Does
Penetration testing tools weren't designed for systems that understand natural language. Sixi AI was — from day one.
46 autonomous agents probe for prompt injection, MCP tool poisoning, AI router MITM, indirect content poisoning, data exfiltration, excessive agency, goal hijacking, and EU AI Act Article 5 prohibited manipulation. The same vectors real adversaries exploit — tested systematically.
Every finding includes the exact payload, the agent's response, severity scoring, and the concrete fix — system-prompt patch, guardrail rule, tool-scope diff. Auditors get evidence. Engineers get the patch.
Every finding maps to EU AI Act articles (Art. 9, 15, 73), OWASP LLM Top 10, MITRE ATLAS, and DORA. Produces Annex IV §2(g)-ready technical documentation. Built for the teams that answer to notified body auditors, not just engineering.
REST chatbots, MCP tool servers, A2A agent networks, WebSocket gateways. One consistent methodology, regardless of how your agent is deployed.
How It Works
Provide your endpoint URL and select the protocol — REST, MCP, A2A, or WebSocket. Configuration takes under a minute.
46 attack agents execute 330+ techniques in parallel. Adaptive rewriting generates novel variants on the fly. Go grab a coffee.
Severity-scored findings with reproduction steps. Article 15 robustness evidence, Article 9 risk management inputs, Annex IV §2(g) technical documentation. Export as HTML, PDF, JSON, or BFSI regulatory report.
Each finding ships with the remediation that closes it — system-prompt patches, guardrail rules, tool-scope tightening, MCP permission diffs. Prioritised by impact. Re-scan to verify.

Framework Coverage
Every finding references the frameworks your security and compliance teams already work with. No translation layer needed.

About the Author
I design and ship agentic AI systems in production — not PoCs. Primarily on Azure and Microsoft Foundry, with hands-on Python, .NET, Databricks, Copilot Studio, GCP, and AWS. I partner with Product, Engineering, and Data teams to ship AI with secure-by-default architecture spanning hybrid cloud and sovereign AI edge (NVIDIA), covering DevSecOps, AI security, and EU AI Act compliance.
Recently shipped: agentic AI systems with vision, speech, and video — guardrailed and running across Azure, GCP (Gemini), Kubernetes, Mistral, and NVIDIA edge.
Why this project: I built Sixi AI to pressure-test my own thinking about how to red-team production agents — and to have a hands-on reference for what EU AI Act Article 15 robustness evidence actually looks like, end to end.
