## AI overview

A practical tutorial on building a custom Model Context Protocol server from scratch with Node.js. It explains how MCP connects AI assistants such as Claude to external data sources and tools, then uses a bin collection reminder system backed by JSON data as the example.

## Source excerpt

Ever wished your AI assistant actually knew your stuff? Your files, your schedule, or even a custom data source? That's exactly what the Model Context Protocol (MCP) makes possible. MCP is an open standard for connecting AI assistants like Claude to external data sources and tools. Think of
