📘 Introduction

In the rapidly evolving world of artificial intelligence, interoperability is emerging as a critical challenge. With multiple agents, tools, memory systems, and models working in tandem, the need for a universal “plug-and-play” protocol is greater than ever. Enter the Model Context Protocol (MCP) — a new standard designed to unify how AI agents understand and manage context.

Just like USB-C revolutionized hardware connectivity by replacing a mess of ports with a single, universal interface, MCP aims to do the same for AI systems. In this post, we'll explore what MCP is, why it matters, and how it may become the foundational layer for a modular, interoperable AI ecosystem.

🔌 The Problem: Context Is Fragmented

AI agents are becoming more capable, but with increased capabilities comes complexity. Agents now need to:

  • Pull data from various sources (documents, APIs, memory).
  • Maintain long conversations or task states.
  • Collaborate with tools and other agents.
  • Switch between models (LLMs, vision models, planners).

However, each system has its own way of representing "context", making it difficult for tools and agents to work together seamlessly. This lack of standardization results in duplicated effort, vendor lock-in, and brittle integrations.

💡
Just like you once needed separate ports for video, charging, and data — we now have separate formats for prompts, memory, and tools.

📦 What Is MCP?

Model Context Protocol (MCP) is an emerging open protocol that defines a standardized way to structure and exchange contextual data between models, agents, tools, and memory systems.

At its core, MCP provides a portable container for context, which can include:

  • A system prompt
  • A message history
  • Embedded tools/functions
  • Agent goals or tasks
  • External knowledge (e.g., retrieved documents)
  • Model-specific configuration
💡
By creating a universal context interface, MCP allows agents to be modular, composable, and interoperable across different environments and model providers.

🔁 Why "The USB-C Port for AI"?
