Vault-0
Encrypted secret vault and policy engine for AI agents
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.

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…

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…

OneCLI – OSS credential gateway that keeps secrets out of AI agentsJul 2026 · github.com · ▲110hey HN, Jonathan and Guy here, creators of OneCLI (https://onecli.sh/). OneCLI is an open source vault for AI Agents. Traditional vaults are used to store your secrets and, on demand, provide them to you all in a secure way, trusting the person to keep them safe. We figured that in the agent's world, this is not the case, as you don't know what happens with the secret after it's delivered to the agent, or where it was saved. Or maybe someone even manipulated them to hand them over... From that understanding, we decided to build a network gateway that sits between your AI…
