OWASP Agent Memory Guard – Protect OpenAI Agent Memory from Poisoning Attacks

[vgudur-dev]

What is it?

OWASP Agent Memory Guard (AMG) is an open-source Python library that protects AI agent memory from poisoning attacks. If you're building agents with OpenAI's API that use persistent memory (conversation history, RAG, vector stores), AMG scans every memory write for:

• Prompt injection attempts
• PII leakage (API keys, passwords, SSNs)
• Memory tampering & instruction override

Quick Start

pip install agent-memory-guard

from agent_memory_guard import MemoryGuard

# Wraps any memory store transparently
guard = MemoryGuard(your_memory_store)
guard.add_message(msg)  # Scanned before storage

Results

• 92.5% detection rate on AgentThreatBench
• <5ms latency per scan
• Zero config needed
