Pentest-AI: It Doesn't Flag, It Proves
Pentest-AI is an open-source AI penetration-testing CLI and MCP server. It runs locally and keeps findings as candidates until a machine oracle re-runs the exploit and reproduces it three for three, only then turning them green.
About this tool
Pentest-AI is an open-source AI penetration-testing CLI and MCP server designed for local self-hosted security testing. It integrates with AI clients such as Codex and Claude Code through MCP, allowing these clients to call its testing tools. Its core workflow revolves around evidence: findings start as candidates and are only confirmed as verified after a machine oracle re-runs the exploit and reproduces it three consecutive times. This ensures that reported findings are proven, not just flagged. Installation is via pipx or pip, and it supports Linux, macOS, Windows, and Web platforms. It is MIT-licensed and free to use, with free, freemium, subscription, one-time, and credit-based models available.
