MemoryGuard
A LOCAL SECURITY GATEWAY FOR AI AGENT MEMORY

Keep your agent's memory
honest & uncompromised.

MemoryGuard sits between your AI agent and its long-term memory — stopping prompt injection, credential leakage and memory poisoning before they can do harm.

🛡️ Blocks credential leakage

Private keys, API tokens and JWTs are rejected before they ever reach persistent memory. Only a content hash is audited — never the secret.

🧠 Catches prompt injection

Obfuscated, encoded and split attacks are quarantined — and the combined recall bundle is re-scored right before an action executes.

🔐 Authority bound to origin

Derived content can never outrank its source. High-risk actions require a sealed, action-scoped human authorization.
