4. phantom-secrets

   3 1 13 9.3 Rust

   Stop AI coding agents from leaking your API keys. Local proxy + MCP that swaps real secrets for phm_ tokens — works with Claude Code, Cursor, Windsurf, and Codex.

   

   Project mention: Show HN: Phantom – Let AI use your API keys without leaking them | news.ycombinator.com | 2026-03-28

5. execwall

   4 3 10 8.8 Rust

   OpenClaw Execution Firewall - Seccomp-locked AI agent sandbox with policy-enforced command governance, WhatsApp/Telegram integration, and Python isolation. Deploy on Oracle Cloud Free Tier.

   

   Project mention: Execwall – firewall to stop ModelScope CVE-2026-2256 (AI agent command injectn) | news.ycombinator.com | 2026-03-13

6. veto

   5 1 7 8.2 Rust

   🔑 Human-in-the-loop confirmation for AI Agents. Let your AI deploy, delete, push — with your fingerprint. (by runkids)

   

   Project mention: Show HN: Veto – Intercept dangerous commands before AI executes them | news.ycombinator.com | 2026-01-27

   - Full audit trail

   Currently supports Claude Code (via hooks). Looking into Moltbot integration but it doesn't expose hooks yet — if anyone has ideas, I'm all ears.

   Feedback welcome.

7. vellaveto

   6 1 6 9.9 Rust

   Agentic security control plane for MCP and AI agent tool calls. MCP-native policy gateway with topology discovery and audit. (by paolovella)

   

   Project mention: Show HN: VellaVeto – fail-closed gateway for MCP tool calls | news.ycombinator.com | 2026-03-28

8. shield

   7 2 2 - Rust

   Local guardrails for AI coding agents. Wraps any MCP server and blocks destructive tool calls — DROP TABLE, rm -rf, force-push, unscoped UPDATE/DELETE — before they execute. Free, open-source, runs entirely on your machine. (by AperionAI)

   

   Project mention: Aperion Shield v0.7 – guardrails for AI coding agents now run as Git hooks | news.ycombinator.com | 2026-05-26

9. project-guardian

   8 1 2 8.7 Rust

   AI Guardian Firewall — a local, user-space, agent-agnostic firewall that mediates an autonomous AI agent's actions (files, shell, network, services) with a deterministic policy boundary, a tamper-evident audit log, and a human-in-the-loop approval cockpit. No kernel modules. Apache-2.0.

   

   Project mention: A user-space firewall that gates an AI agent's actions | news.ycombinator.com | 2026-06-29

10. fishnet

    9 1 2 8.4 Rust

    Security proxy for AI agents (OpenClaw, LangChain, CrewAI). Protects API keys, enforces spend limits, blocks dangerous endpoints. Local-first Rust binary — your credentials never leave your machine. (by fishnetproxy)

    

    Project mention: How I Saved 20,000 Gas Per Transaction by Reordering One Line in Solidity | dev.to | 2026-03-01

    While building a smart wallet contract for Fishnet — an AI agent transaction security proxy — I ran a self-imposed code review and found a subtle optimization that every Solidity developer should know about.

11. actra

    10 2 2 8.9 Rust

    Actra - control what runs before it runs, controls what actions are allowed before they execute. Evaluate policies across APIs, workflows and AI agents in real time. (by getactra)

    

    Project mention: The Claude Code Leak Is a Warning: AI Infrastructure Is Outpacing Control | dev.to | 2026-04-05

12. aegis-shellguard

    11 1 2 9.8 Rust

    Aegis — the shell guard for AI coding agents. Destructive commands from Claude Code, Codex, or Cursor pause for your approval, with a snapshot taken first — so even a "yes" is recoverable.

    

    Project mention: I built Aegis — a firewall between AI coding agents and your shell | dev.to | 2026-07-09

    I want to be honest here, because security tools that oversell themselves are a plague: Aegis is a heuristic guardrail, not a sandbox. It is not a privilege boundary. A determined attacker — or a sufficiently creative agent — can construct commands that evade pattern-based classification. There's a full threat model (https://github.com/IliasAlmerekov/aegis/blob/main/docs/threat-model.md) in the repo that spells out exactly what's in and out of scope.

13. helmr-core

    12 1 0 5.8 Rust

    Constrained autonomy runtime for AI agents.

    

    Project mention: Show HN: HELmR – A runtime control layer for autonomous agents | news.ycombinator.com | 2026-03-09

14. Analemma-GVM

    13 1 0 - Rust

    A governance runtime for AI agents, built on Linux kernel security primitives.

    

    Project mention: GVM-light weight governance runtime for AI Agents:Rust proxy, Linux kernel features(seccomp-bpf, namespace, overlayfs) | dev.to | 2026-04-10
