MCP vs API: The protocol every developer needs to know

In this video, Smitha Kolan breaks down how Model Context Protocol (MCP) works, how it's different from traditional APIs, and why it's becoming the new standard for connecting AI agents to tools, data, and systems. For decades, APIs have been the universal handshake between software systems: clean, predictable, and built for programs talking to programs. But Large Language Models (LLMs) don't just call a single endpoint. They need to chain tools together, interpret unstructured data, and reason about what to do next. APIs weren't designed for that. MCP is. Learn how MCP allows models to autonomously discover and use tools without manual hardcoding or constant prompt engineering, including a real world example of how an AI agent can connect to services like Gmail, Notion, and Jira through MCP without writing custom integration code for each one.
