Your New AI Red-Teamer Runs on Python
CAI is a lightweight Python framework for building AI agents that automate offensive and defensive security tasks, from vulnerability discovery to CTF competitions.

What it does
CAI is a Python framework that turns large language models into modular security agents. It packages prefab tools for reconnaissance, exploitation, and privilege escalation so researchers can automate vulnerability discovery and mitigation. The maintainers bill it as the de facto framework for AI security, citing thousands of users and real-world case studies in industrial robots, web platforms, and operational technology.
The interesting bit
Rather than treating LLMs as chatbots, CAI deploys them as autonomous participants in CTFs and bug bounties—complete with guardrails to dampen prompt injection and reckless command execution. The project’s disclosed case studies include uncovering exposed credentials in European heat pumps and inspiring HackerOne’s production vulnerability deduplication agent.
Key highlights
- Supports 300+ models, including OpenAI, Anthropic, DeepSeek, and Ollama.
- Modular agent architecture for specialized offensive and defensive tasks.
- Built-in guardrails against prompt injection and dangerous command execution.
- Battle-tested claims include a top-ten finish in the Dragos OT CTF 2025 and disclosed findings in humanoid robots and industrial control systems.
- Research-backed, with multiple technical reports on arXiv.
Verdict
Red-teamers and security researchers experimenting with autonomous LLM agents will find a focused toolkit here; generalist developers looking for broad AI orchestration should look elsewhere.
