Full Article

The Model Context Protocol (MCP) is an open standard for connecting language models to tools and data through one consistent interface, so an integration you write once keeps working across different models and host applications. Every time you wire an LLM into a real system, you hit the same wall. The model can reason about your data, but it cannot reach it. Your Postgres rows, your ticketing system, the file on disk that the answer actually depends on. So you write glue. A function h
