MCP Example Repo

This repository is a small, portable example of how to structure markdown documents so they are useful to both humans and MCP-aware agents.

The goal is not to model one specific product. The goal is to show a clean, practical pattern for documentation that can be indexed, searched, and extended without dragging in company-specific assumptions. For real-world use, a comprehensive KB must be compiled in order to reduce endpoint hallucinations and provide a "source-of-truth" for autonomous coding agents. These files act as a starting point.

What is in this repo

• 00-index.md: the top-level map of the documentation set
• 01-architecture-and-routing.md: a generic architecture guide covering routing, middleware, controllers, services, and the data layer

Why this is useful

A good MCP example should do more than prove that markdown files can be read. It should show a structure that has real operational value.

This repo demonstrates:

• stable frontmatter that an MCP server can index
• topic-focused documents that are easy for agents to retrieve
• guidance that applies to real systems, not just toy examples
• a format that can grow into a larger knowledge base

Design principles

• Keep each document focused on one concern.
• Prefer generic architecture patterns over business-specific workflows.
• Use metadata that helps an agent decide which file to read.
• Write content that is concrete enough to act on, but portable across stacks.

How an MCP server could use these files

An MCP server or agent could:

• list available documents from 00-index.md
• route architecture questions to 01-architecture-and-routing.md
• use frontmatter fields such as feature_id, keywords, tasks, and invariants to improve retrieval
• answer code placement questions without scanning a full application codebase

Real-world implications

The architecture document is intentionally practical. It covers concerns that show up in production systems:

• keeping routers thin
• isolating business logic in services
• reusing the same service logic across APIs, workers, and automation
• separating persistence concerns from domain rules
• preserving observability with logs, metrics, and trace identifiers

That makes this repo useful as both:

• a proof of concept for MCP document retrieval
• a starting point for a real internal engineering knowledge base

Extending the example

Good next documents would include:

• authentication and authorization
• background jobs and task processing
• integrations and external APIs
• persistence and data modeling
• observability and operations

When adding new files:

• keep file names stable
• avoid overlapping topics
• keep examples framework-agnostic unless the framework is the topic
• update 00-index.md so the documentation set stays navigable

Who this repo is for

• developers building MCP demos
• teams experimenting with agent-friendly documentation
• anyone who wants a minimal example of structured technical docs with practical value

Repository status

This repository is intentionally small. It is meant to be easy to understand in one pass and easy to adapt for a larger proof of concept or GitHub example.
