What an MCP Server Actually Does

An MCP server gives an LLM a standard way to reach your data and run tools against it. Every API is built differently, and the Model Context Protocol puts one interface over all of them, which is why Anthropic's standard gets compared to USB C.This episode covers what the standard defines, how tools and resources set the boundaries on what an AI can do with your systems, and what you get by writing a server yourself. We built one for our own AI-ready data model and hit a context problem along the way: the model would skip the business context files and bluff its way through an answer, then admit it never read them when asked directly. The fix was a token buried in those documents that the server checks before it will run any other tool.If you work in data, BI, or analytics engineering and you are weighing a vendor's MCP server against building your own, start here.Like and subscribe for straight talk on data, AI, and running a modern business on real numbers.Blue Margin builds and manages data platforms on Microsoft Fabric and Power BI for mid-market and private equity backed companies.
