0sec Labs open-sources 0, an AI security harness for code review, pentesting and fixes

Another AI security tool just went open source. 0sec Labs has released 0, an AI security harness for code review, penetration testing, reverse engineering and fixes, according to MarkTechPost.

It runs locally in three ways: a browser console, a headless command-line tool for scripts and CI, and an MCP server so other agents can call it. You bring your own model provider.

Details are thin: the summary doesn't say which models it supports best, how it's licensed or how it performs. But the shape is notable. Local-first, provider-agnostic security harnesses are the defender's answer to free models that now hack nearly as well as gated ones: if attackers can point open tools at your code, you want the same capability running in your own pipeline first, without sending your source to a third party.

Scoreboard update: AI +1. Defenders get a free, local AI security harness to run on their own code.

Stay undead.
