What is MCP Server?
The Model Context Protocol (MCP) lets AI assistants like Claude or Cursor call into external data and tools through a well-defined protocol rather than ad hoc plug-ins. For architecture, an MCP server exposes systems, containers, ADRs, and conformance data so the assistant can ground its answers in your real model — not a hallucination of what similar projects look like.
