Greywall

Prefix any AI coding agent with `greywall --` for a live feed of every read, write, and connection. Allow by default; ask mode and deny rules opt-in via config. Linux and macOS.

What it does

AI agents run on your machine, with your credentials, making network requests you never see. Greywall puts a deny-by-default layer in front of any CLI agent. Run greywall -- claude and it restricts file access, blocks outbound connections, and shows you a live dashboard of what the agent is trying to reach. You decide what to allow. Nothing is containerized. Your workflow stays the same but safer. It runs on Linux and macOS and costs nothing.

See every read, write, and connection your AI agent attempts on Linux and macOS. Allow by default, deny whatever you want in config. $ curl -fsSL https://raw.githubusercontent.com/GreyhavenHQ/greywall/main/install.sh | sh One install, then prefix any local agent. Works on Linux and macOS. Running Greywall across multiple teams? We're building a managed governance layer. The agent read a production key from .env and called the live API to test its changes. The action was plausible. The boundary was missing. The default lets the agent run while Greywall logs every read, write, and connection in the activity feed. Switch to ask or deny mode mid-session when you want stricter behavior. Greywall…from greywall.io

    The only way to go fast is full YOLO mode in your coding agent. I've got the local sandbox figured out (pro tip: Incus VMs work great) but I wanted to keep my agents from doing things like inadvertently blowing up my cloud services or chasing a prompt to POST to some random website. I struggle most with this on my side projects where my permission model isn't quite as robust as it is at the office. I started with a firewall on the Incus container but every time the agent needed access to something new, I was poking more holes in it - and it didn't differentiate between HTTP verbs. I've been…

    Launched Blocks.ai today - the control plane and network layer for agents. One outbound connect, zero-trust security, and A2A protocols built in. Connect your agent to any frontend you build or any specialist agents you need regardless of runtime without tons of messy middleware. I work to solve agentic problems with Blocks.ai AMA :)

    Hi HN, I’m the creator of Cordum. I’ve been working in DevOps and infrastructure for years (currently in the fintech/security space), and as I started playing with AI agents, I noticed a scary pattern. Most "safety" mechanisms rely on system prompts ("Please don't do X") or flimsy Python logic inside the agent itself. If we treat agents as autonomous employees, giving them root access and hoping they listen to instructions felt insane to me. I wanted a way to enforce hard constraints that the LLM cannot override, no matter how "jailbroken" it gets. So I built Cordum. It’s an open-source…

    Clink – Bring your own CLI Agents, Ship instantly2025 · clink.new · ▲22

    Clink lets you use the coding agents you already pay for (Claude Code, Codex CLI, Gemini CLI, Z.ai GLM) to build → live-preview → ship apps in an isolated container. No token purchases, no extra cost for coding. Just link your existing Claude/OpenAI/Gemini account and start building and deploying instantly. Why we built this: Claude Code is our go-to for coding, but it lacked preview + deploy capabilities. We didn't want to pay Lovable again just for that. Different agents excel at different tasks - Claude Code for versatility, Codex for complex work, GLM for speed. We needed one…
