MCP (Model Context Protocol) helps to feed more data to an LLM. For example, it can make an LLM search through your Google Drive. It does not stop at reading data, you can even instruct an LLM to create a ticket in your project management system. But why stop there? You can also use MCP to connect to a Phillips Hue light and let an LLM control the colour of the light in your room while you’re talking to it. In this talk we’re going to wrap up the sleeves and build our very own MCP server with Node.js. So expect a lot of live coding!
