Memory · Vault

Secrets your agent can use, but not leak.

The Knowledge Vault is per-namespace AES-256-GCM storage for credentials, API tokens, signing keys, and any data classified as sensitive. Zeroize on drop. Key rotation built-in. No plaintext in logs.

Capabilities

What it does.

Every capability is production-grade. No flags, no betas — these ship the day you adopt Minds.

AES-256-GCM
Authenticated encryption with per-namespace keys via HKDF-SHA256.
Four sensitivity tiers
Public · internal · confidential · critical. RBAC enforced per tier.
Key rotation
Rotate root keys without re-encrypting every blob. Per-blob KEK.
Zeroize on drop
Decrypted material is wiped from memory on the `Drop` path.
No plaintext logs
Tracing redacts vault material. Never appears in stdout or audit logs.
Capability tokens
Vault reads require an explicit capability — no ambient access.
API

A few lines is all it takes.

The SDK reflects the conceptual model directly. No glue code, no orchestrator, no learning curve beyond the data shape.

exampletypescript
// Write a credential. Tier it.
await minds.memory.vault.put({
  key: "stripe.api_key",
  value: process.env.STRIPE_KEY,
  sensitivity: "critical",
  ttl: "90d",
});

// Read it from within a capability-scoped procedure.
const key = await minds.memory.vault.get("stripe.api_key", { capability: token });
