Understanding AI Agents & Protocols
A non-technical guide to AI agents and the emerging protocol standards for product leaders and executives. Learn what agents are, why they matter for your product, and how the industry is standardizing agent communication through protocols like MCP, A2A, and AG-UI.
By the end of this path, you’ll understand the difference between chatbots and agents, how agents connect to external tools and data, and what enterprise agent deployment looks like. You’ll be equipped to evaluate whether your product needs agent capabilities and what infrastructure choices your team should be making.
This path draws from McKinsey, three AI providers (Anthropic, Mistral, AG-UI), and an enterprise agent platform (CrewAI), covering both the strategic context and the practical implementation landscape.
Steps
- What Is an AI Agent?

beginner
McKinsey's explainer on AI agents — what they are, how they differ from chatbots, and how they will impact business operations and the workforce.
Start with McKinsey's explainer — the clearest non-technical introduction to AI agents. The key distinction is between chatbots (which respond to prompts) and agents (which can plan, use tools, and take actions autonomously). This reframes what 'adding AI to your product' can mean: not just a smarter search box, but an autonomous workflow that handles multi-step tasks. Establish this conceptual foundation before reading provider-specific docs.

Now see what agents look like in practice from a major AI provider. Anthropic's agent skills framework shows how agents are built from composable capabilities — think of skills as job descriptions for AI workers. The key concept for product leaders is that agents are assembled from reusable building blocks, not built monolithically, which affects how you scope and phase AI features.
- What is the Model Context Protocol (MCP)?

beginner
MCP (Model Context Protocol) is to AI what USB-C is to hardware — a universal connector that lets AI agents access tools and data sources through a standard interface. Understanding MCP matters for product leaders because it determines how easily your AI features can integrate with existing systems (databases, APIs, SaaS tools). If your engineering team mentions MCP, this is what they're talking about.
- Agents Introduction

Introduction to Mistral's agent system — autonomous task execution with tools, state persistence, connectors (code interpreter, web search), and multi-agent collaboration.
Mistral's agent system provides a second provider perspective. Notice the built-in connectors for code execution, web search, and document retrieval — these represent the kind of 'batteries included' capabilities that differentiate agent platforms. Seeing the same concept from multiple providers helps you understand what's universal about agents versus what's provider-specific.
- MCP, A2A, and AG-UI

Understanding how AG-UI complements and works with MCP and A2A
The emerging agentic protocol stack has three layers: MCP for tool access, A2A for agent-to-agent communication, and AG-UI for streaming agent actions to user interfaces. For product leaders, this architecture signals that the industry is converging on standards — similar to how HTTP standardized the web. Understanding these layers helps you evaluate whether your engineering team's architecture choices will be future-proof.
- CrewAI AMP

Deploy, monitor, and scale your AI agent workflows
CrewAI AMP shows what enterprise agent deployment looks like in practice — a managed platform with SSO, role-based access, and audit trails. For product leaders, this represents the 'buy' option for agent infrastructure: instead of building agent management from scratch, platforms like this handle deployment, monitoring, and compliance. Compare this with building directly on provider APIs to understand the build-vs-platform tradeoff.
