OneCLI (YC S26, 88 HN points) launched an open-source sandboxed agent harness for teams. This workflow builds the same architecture: Docker-isolated agent sandboxes, a shared tool registry for team-wide reuse, and per-developer agent budgets for fair resource allocation.
A developer built a 1.3M-line agent-native OS in Rust while homeless — the HN story captured the imagination of the agent community. This workflow breaks down the architecture and shows how to build your own agent-native operating system: scheduling, memory isolation, and tool access control for autonomous AI.
Ghidra MCP (356 HN points) brought 110 reverse engineering tools to Claude Desktop. This workflow builds a production-grade binary analysis pipeline: connect Ghidra's decompiler, disassembler, and data flow analyzer to any MCP client for AI-assisted vulnerability discovery.
HexStrike AI's MCP server gives LLM agents autonomous access to 150+ cybersecurity tools including Nmap, Metasploit, Burp Suite, and custom exploit scanners. Build a production-ready MCP security server with sandbox isolation and audit logging.
MCP-Scanner (168 HN points) automated the process of finding vulnerabilities in MCP servers. This build creates a FastMCP server that scans any MCP server for prompt injection, data exfiltration, unsafe tool calls, and resource abuse — then reports findings to Claude Desktop or Cursor.
WhatsApp MCP (229 HN points) brought messaging to AI agents. This build creates a FastMCP server for Twilio WhatsApp API integration, letting Claude and Cursor send messages, manage groups, and handle media from agent workflows.
Safari MCP (272 HN points) connects Safari's Web Inspector to Claude Desktop, giving AI agents live DOM inspection, network logging, console debugging, and performance profiling. Here's how to build and deploy it.

OpenAI confirmed it cannot rule out that Astra has critical-level cyber capabilities, triggering an unprecedented safety gate. The 10T-parameter model's release is now indefinite.
Your multi-agent system has a cache coherence problem. When three agents read and write shared state simultaneously, 34% of deployments experience silent data corruption.
When your agent crashes at step 8 of a 12-step workflow, you lose everything. This Temporal MCP Server gives agents durable execution that survives crashes, deployments, and network failures.
Easel (380+ GitHub stars from ZJU-REAL) is an open-source AI agent for social media that discovers trends, creates platform-native content, publishes across channels, and learns from engagement metrics. A full architecture deep dive for automated social media workflows in 2026.
