Show HN: Personal Vault – Own your personal context, let AI agents query it

Mon, 02/23/2026 - 12:52pm

Every AI agent I use asks for the same context — my name, preferences, addresses — and I keep pasting it into different apps that each store their own copy.

Personal Vault is an encrypted local store for personal data with an MCP server so AI agents can query it with scoped access. You own the keys, the data never leaves your machine unless you allow it.

This isn't about agents talking to agents. It's about making the agent that works for you actually know who you are — with your permission, on your terms.

Use cases that click immediately: - Travel booking: agent pulls passport, loyalty numbers, seat pref, TSA PreCheck, dietary requirements - Form filling: government forms, insurance, visa docs — agent fills 90% of the fields from your vault

Technical details: - AES-256-GCM per field, Argon2id KDF, HKDF subkeys per category - Sensitivity tiers control what agents can see (public → standard → sensitive → critical) - Every access is audit-logged, tokens are scoped and revocable - Written in Go, no CGO, single binary, ~2500 lines

Install: curl -fsSL https://www.personalvault.dev/install.sh | sh GitHub: https://github.com/lovincyrus/personal-vault

Cripix Technology?

Mon, 02/23/2026 - 12:01pm

CRIPIX seems to be a new and unusual concept. I came across it recently and noticed it’s available on Amazon. The description mentions something called the Information Sovereign Anomaly and frames the work more like a technological and cognitive investigation than a traditional book. What caught my attention is that it appears to question current AI and computational assumptions rather than promote them. Has anyone here heard about it or looked into it ?
