Vault-0

What it does

Vault-0 is a local desktop app that encrypts your AI agent's API keys and injects them ephemerally at launch. Keys exist on disk for about 2 seconds instead of sitting in plaintextenv files forever. It also runs a policy engine that enforces domain allow/block lists, output redaction, and spend caps on outbound requests. Built for OpenClaw agents with MCP hardening, a SHA-256 chained evidence ledger, and native x402 payment support. Rust + Tauri, macOS, fully local.

Vault-0: Agent Security, Monitor & x402 Wallet for OpenClaw. Encrypted secret vault, real-time agent monitor, policy enforcement, and native x402 payments — built with Rust + Tauri. - 0-Vault/Vault-0

  Agent Vault – Open-source credential proxy and vault for agentsApr 2026 · github.com · ▲156

  Hey HN! Today we're launching Agent Vault - an open source HTTP credential proxy and vault for AI agents. Repo is at https://github.com/Infisical/agent-vault, and there's an in-depth description at https://infisical.com/blog/agent-vault-the-open-source-crede.... We built Agent Vault in response to a question that been plaguing the industry: How do we give agents secure access to services without them reading any secrets? Most teams building agents have run into this exact problem: They build an agent or agentic system and come to realize at some point…

  OneCLI – Vault for AI Agents in RustMar 2026 · github.com · ▲161

  We built OneCLI because AI agents are being given raw API keys. And it's going about as well as you'd expect. We figured the answer isn't "don't give agents access," it's "give them access without giving them secrets." OneCLI is an open-source gateway that sits between your AI agents and the services they call. You store your real credentials once in OneCLI's encrypted vault, and give your agents placeholder keys. When an agent makes an HTTP call through the proxy, OneCLI matches the request by host/path, verifies the agent should have access, swaps the placeholder for the real…

  AI VaultJul 2026 · ps-aditya.github.io · ▲5

  I built Vault-AI to solve a problem I kept running into when building AI apps: API keys and secrets end up scattered in .env files, hardcoded, or shared insecurely. Vault-AI is a lightweight, self-hosted secrets manager — kind of like HashiCorp Vault, but simplified and aimed at AI workloads. It runs in Docker, comes with a simple CLI, and manages tenants, token-based auth, secret rotation, rollback, version history, and audit logs. Quickstart: git clone → ./start.sh → vault-ai store/get Repo: https://gitlab.com/vaultaiproject/vault-ai.git Would love feedback…

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  I spent 3 years reverse-engineering a 40 yo stock market sim from 1986▲721

  Hello my name is Ben Ward for the past 3 years I have been remastering the financial game Wall Street Raider created by Michael Jenkins originally on DOS in 1986. It has been a rough journey but I finally see the light at the end of the tunnel. I just recently redid the website and thought maybe the full story of how this project came to be would interest you all. Thank you for reading.
