New - Vaulty MCP: the vault built for AI agents

Encrypt everything.
Expose nothing.

Vaulty is the secure data vault API developers love and attackers hate. Encrypt, store, and compute on sensitive data - PII, secrets, credentials - with HSM-backed keys and secure enclaves. No cryptography degree required.

Encryption on every record: AES-256
Data sealed at rest, in transit & in use: 100%
Plaintext visible to Vaulty - or attackers: 0 bytes
From signup to first vaulted record: <10 min

How it works

Two calls. Zero exposure.

Replace risky database writes with vault.store() andvault.compute(). Your app handles references - never raw data.

01
Store - sealed on arrival
Data is encrypted with AES-256 the moment it reaches Vaulty. Keys are born inside FIPS 140-2 HSMs and never leave the hardware.
02
Compute - answers without exposure
Search, validate, mask, and analyze inside secure enclaves. Your app gets results; the plaintext never leaves encrypted memory.
03
Unlock - only with the user
Bind keys to passkeys, biometrics, or MFA. Not you, not your admins, not even Vaulty can decrypt without the user's say-so.

app.js - @vaulty/sdk

import { Vaulty } from '@vaulty/sdk';

const vault = new Vaulty(process.env.VAULTY_API_KEY);

// Encrypt + store in one call - keys never leave the HSM
const ref = await vault.store({
  user: 'usr_8f3a2c',
  data: { card: '4242 4242 4242 4242', ssn: '514-22-9048' },
  policy: { unlock: 'user-auth' },
});

// Ciphertext in, answers out - plaintext never touches your app
const last4 = await vault.compute(ref, 'mask:last4', { field: 'card' });
// => '•••• 4242'

Why Vaulty

Security that would take you years to build

The full stack of modern data protection - behind one API that feels like any other SDK.

Zero-trust by default

Everything is encrypted before it's stored. If Vaulty is ever breached, attackers walk away with ciphertext and nothing else.

HSM-backed keys

Keys live in FIPS 140-2 hardware security modules - the same tamper-resistant vaults banks and governments rely on. Never exported, never in plaintext.

Compute on encrypted data

Secure enclaves let you search, validate, and transform data while it stays encrypted in memory. The host OS - and Vaulty itself - can't peek.

User-bound encryption

Tie decryption to passkeys, biometrics, or MFA. Ship the feature your users actually want: "not even we can read your data."

Compliance guardrails

GDPR, CCPA, HIPAA, and PCI-DSS friendly out of the box - per-user keys, consent controls, access expiry, and audit-ready reporting.

Audit everything

Every access, every operation, every consent - logged and queryable. Hand your auditors a timeline instead of a shrug.

Vaulty MCP

The easiest vault your AI agents will ever use

Agents shouldn't carry secrets in their context windows. With the Vaulty MCP server, any agent - Claude, GPT, or your own - stores and uses sensitive data through the vault, and plaintext never enters the conversation.

One command to connect. npx -y @vaulty/mcp - your agent gets all five vault tools instantly, fromvault_store to vault_audit.
Secrets stay out of context. Agents pass vault references, not raw values - prompt leaks stop mattering.
Policy-scoped autonomy. Give agents exactly the operations they need, audit every call they make.

Built for

Wherever data is radioactive

Fintech

Vault cards, accounts, and KYC data. Shrink PCI scope to a single API call and ship zero-knowledge account features your competitors can't.

Healthcare

Store and compute on PHI without ever exposing it. HIPAA-friendly architecture with per-patient keys and complete audit trails.

SaaS & Identity

Per-user encryption for PII at any scale. Already securing unified identity data for Universal Name Space (UNS).
