Agent Vault – Open-source credential proxy and vault for agents
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…

In plain words
Agent Vault is an open-source HTTP credential proxy and vault designed for AI agents. It enables agents to access services securely without directly handling or reading secrets, addressing the risk of credential leakage through prompt injection or non-deterministic agent behavior. The tool acts as an intermediary that manages authentication, allowing teams to build agentic systems that require service access while maintaining credential isolation and security.

From the sources
AI agents need API keys, database passwords, and tokens to do their jobs, but today those credentials get scattered acrossenv files, hardcoded configs, and shared secrets with no access control. agent-vault gives every agent its own encrypted identity. Secrets are encrypted locally using age encryption and stored in a Git repo as ciphertext. No server. No SaaS. No trust in the Git provider required. The repo is just an encrypted blob store with built-in versioning and collaboration.

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

With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
