Google Open-Sources Mantis: A Modular Skills Toolkit That Lets Coding Agents Find, Reproduce and Patch Vulnerabilities

AITopTools Editorial TeamSeptember 9, 2026

What changed

Google has released Mantis, an open-source toolkit that gives AI coding agents a structured process for reviewing software security. It can scan code, remove likely false alarms, recreate suspected bugs in an isolated test environment, suggest fixes, test those fixes again, and assess risk.

What this means for you

Developers can use the Apache 2.0 toolkit to automate more of the vulnerability-review process across different coding setups. It is currently documented as demonstration-only, so users should not treat it as a production-ready security solution.
