⚡ TL;DR (This Week in AI Agents)

A2A is gaining significant traction. Many people believe Google is trying to replace MCPs with A2A, but I see it differently. MCP is like the TCP protocol. It enables agents to use tools. A2A, on the other hand, is more like HTTP, a standardized way for agents to communicate with each other

🔥 Top Stories

OpenAI has released o3 and o4-mini
o3 is OpenAI’s most advanced reasoning model yet. It excels at complex, multi-step tasks in coding, math, science, and visual perception, making 20% fewer major errors than its predecessor, o1. Read more

New TypeScript AI Agent Framework
VoltAgent is a new TypeScript framework for building AI agents. It supports dynamic prompts, built-in persistent memory, and a visual playground for testing agentic workflows. It feels similar to CrewAI, but with TypeScript. Read more

Google Standardizes Agent to Agent Communication
Google has introduced a new standard for Agent-to-Agent (A2A) communication. Until now, agents lacked interoperability, and this new protocol aims to solve that. Read more

📚 Resources You Can't Miss

🤖 A2A Protocol by Google - Google’s Agent2Agent Protocol. Collaborative way to help agents across different ecosystems communicate with each other.

🕵️ “Vibe Codes” will get hacked - new vulnerability involving how Cursor, Windsurf and GitHub Copilot interpret certain Unicode characters. You can copy/paste things you can’t see, that can lead to backdoors, RAT (Remote Access Tools) and more. Be careful what you copy and paste!

⚙️ Build Multi-Agent AI App with Google’s A2A Protocol - A great guide on building multi-agent systems using Google’s Agent Development Kit (ADK), the Agent-to-Agent (A2A) protocol, and MCP. 🐍 It’s Python-based, as ADK is built with Python.

💡 My Take

We’re seeing new frameworks and protocols drop every week. Especially from giants like Google, Amazon, and others. That’s a powerful signal. We’re still extremely early in this space, which means now is the time to learn fast, experiment daily, build and ship.

If you commit just a few weeks to testing ideas, shipping agentic flows, and iterating quickly, you’ll be ahead of 99.999% of the world.

Got an idea? Don’t wait. Build it, break it, and rebuild it. The leverage is insane, and growing by the day.

🔎 Sneak Peek: Friday’s Deep-Dive (Premium)

I’ll be sharing deep dives every Friday with my premium community members.

This week, we’re diving into Mastra.ai a TypeScript framework backed by Y Combinator. I’ve been using Mastra extensively to build agents, and it’s incredibly easy to work with. The built-in development playground makes it especially powerful and fun to experiment with.
