Launch HN: OneCLI (YC S26) – OSS sandboxed agent harness for teams

Hi HN, Jonathan & Guy here from OneCLI, an agent harness built for teams, giving every employee a secured, sandboxed personal agent.Here’s what you can do with it: 1. get a sandboxed agent, with all the OneCLI capabilities in place like connect your GitHub account, Gmail, Notion, or Dropbox simply from the chat. 2. deterministic human in the loop approval in the chat itself for things that you need 100% control like sending an email or deleting the Linear ticket. 3. manage team policy in one place, enforced across every agent in the workspace 4. enjoy global connections at the team level, like shared LLM keys or service accounts Here’s a demo: https://www.youtube.com/watch?

v=dlW-44ntpbE We started working on this by accident, even though our careers were in the security space.We were working on a devtool called ChartDB, an open-source DB tool.When OpenClaw took off back in January, we started using it to orchestrate agents on top of ChartDB.We quickly understood there is a big issue around auth.Agents need credentials to do real work, but to give them those secrets would not be the best idea.They keep them in their memory and also write them down to local files and their sessions as plain text.And we knew that agents can easily be fooled into giving up those API keys/secrets.

So we needed some way to control the agent and stop prompt injections from tricking it into using its services for an attacker's benefit.We created OneCLI that started as a vault for AI Agents built in Rust.We found out that most of our demand for OneCLI came from autonomous agents like Hermes, OpenClaw and NanoClaw for individuals and teams.Users looked for useful agents that do things for the person who runs them with two missing parts: 1) managing secrets and permissions. 2) and for teams - multiplayer management.We decided to pivot and provide the agent itself as a harness for teams, to give each employee an agent.

We saw that teams had to deal with setting up their own harness again and again, and basically as we already had the vault as a gateway.We got the idea to provide the missing piece of the agent management out of the box and open source it (Apache-2.0, with a small enterprise exception).We're open source first - the entire platform, not just a small portion of it like other agents, so companies can actually see the code, evaluate it, and trust it instead of taking our word for it.They run it isolated, in their own environment, fully under their control, at production quality, not a locked black box hosted somewhere else.

That means the safety isn't just a promise, it's something they can verify themselves.Combined with real autonomy and least-privilege access, that's what makes it something a company can fully own and trust, not just adopt.We also approach this from a company perspective rather than an individual one.Our solution manages agents on behalf of each employee, wrapped in deterministic guardrails that company admins configure through
