MCP ContentEngineering - Simplified

A simplified Model Context Protocol (MCP) server for raw Markdown content access. This server provides a single powerful tool for accessing raw Markdown files or combining multiple files from directories without any processing or parsing.

🚀 Quick Start

Prerequisites

• Node.js 18+ and npm
• Markdown files or directories containing .md files
• MCP-compatible client (like Claude Desktop, Cursor IDE, or any MCP client)

Installation & Configuration

Option 1: Using npx from GitHub (Recommended)

No installation needed! Just configure your MCP client:

For Claude Desktop (claude_desktop_config.json):

{
  "mcpServers": {
    "mcp-content-engineering": {
      "command": "npx",
      "args": ["-y", "hendrickcastro/MCPContentEngineering"],
      "env": {
        "CONTENT_SOURCE_TYPE": "file",
        "CONTENT_SOURCE_PATH": "/path/to/your/business-rules.md"
      }
    }
  }
}

For Cursor IDE:

{
  "mcpServers": {
    "mcp-content-engineering": {
      "command": "npx",
      "args": ["-y", "hendrickcastro/MCPContentEngineering"],
      "env": {
        "CONTENT_SOURCE_TYPE": "directory",
        "CONTENT_SOURCE_PATH": "/path/to/your/docs/"
      }
    }
  }
}

Option 2: Local Development Installation

1. Clone and setup:

git clone https://github.com/hendrickcastro/MCPContentEngineering.git
cd MCPContentEngineering
npm install
npm run build

2. Configure content source: Create a .env file with your content configuration:

# For single file
CONTENT_SOURCE_TYPE=file
CONTENT_SOURCE_PATH=/docs/architecture-guide.md

# For directory with multiple .md files
CONTENT_SOURCE_TYPE=directory
CONTENT_SOURCE_PATH=/docs/knowledge-base/

3. Configure MCP client with local path:

{
  "mcpServers": {
    "mcp-content-engineering": {
      "command": "node",
      "args": ["path/to/MCPContentEngineering/dist/server.js"]
    }
  }
}

• Check: Use absolute paths for clarity

No .md Files Found

• Issue: No .md files found in directory
• Solution: Ensure directory contains .md files
• Note: Searches recursively in subdirectories

Permission Errors

• Issue: Permission denied when accessing files
• Solution: Ensure read permissions on files/directories
• Check: File ownership and access rights

Configuration Issues

• Issue: CONTENT_SOURCE_PATH not configured
• Solution: Set both required environment variables
• Required: CONTENT_SOURCE_TYPE and CONTENT_SOURCE_PATH

🧪 Testing

Run the comprehensive test suite:

npm test
