 The platform is implemented as a resource-first MCP system with an integrated static documentation surface. The same methodology content powers both MCP resources and the published docs site.
 
+An MCP server is a runtime that exposes machine-readable resources and tools through stable interfaces so AI clients can discover and consume context consistently. Here, the server's role is intentionally narrow: publish canonical methodology documents as resources, keep discovery predictable through a catalog layer, and serve the same source material as pre-built static documentation.

 The system is complete in three layers:
 
 1. Canonical methodology is maintained in Markdown skill documents.

 # Get started
 
+## What this MCP server is
+
+An MCP server is a service that gives AI clients a stable way to discover and read capabilities through defined contracts. In practice, it exposes named resources and optional tools so clients can request context reliably instead of depending on ad-hoc prompts.
+
+This server is designed to publish software methodology as canonical Markdown resources, with a small catalog for discovery, and to serve the same content as a static docs site. The intent is one source of truth for both humans and agents.
