AL-MUNAA: Open-source security layer shields AI agents from prompt injection

By Meridian48 News Desk · Summarised from DEV Community ·

AL-MUNAA is a local security layer for AI agents that detects and blocks indirect prompt injections before they reach the model or tools. It uses four gates—input scanning, tool/action control, output verification, and a signed Threat Antibody Protocol for cross-agent immunity. The project, built during OpenAI Build Week, passes 74 tests and demonstrates blocking a simulated data exfiltration attack.

Meridian48 take
A promising proof-of-concept for agent security, but its real-world effectiveness depends on adoption and robustness against evolving attacks.
