OneTech MCP Server

Extract and document Mendix Studio Pro modules via Model Context Protocol (MCP)

OneTech MCP Server enables AI assistants like GitHub Copilot to interrogate local Mendix .mpr files and extract comprehensive module documentation including domain models, pages, microflows, and enumerations.

🚀 Quick Start

Install Globally (Recommended)

npm install -g @jordnlvr/onetech-mcp-server

Or Use with NPX (No Install)

npx @jordnlvr/onetech-mcp-server

Configure in VS Code

Add to your VS Code settings.json:

{
	"github.copilot.chat.mcp.enabled": true,
	"github.copilot.chat.mcp.servers": {
		"onetech": {
			"command": "npx",
			"args": ["@jordnlvr/onetech-mcp-server"]
		}
	}
}

Or use global install:

{
	"github.copilot.chat.mcp.enabled": true,
	"github.copilot.chat.mcp.servers": {
		"onetech": {
			"command": "onetech-mcp-server"
		}
	}
}

📚 Usage

Once configured, use GitHub Copilot to extract module documentation:

You: "Extract the RequestHub module from D:\Projects\OneTech.mpr"

Copilot: [Uses onetech_extract_module tool]
✅ Successfully extracted 4 files from module 'RequestHub':
  - DomainModel.json (57KB)
  - Pages.json (42KB)
  - Microflows.json (0KB)
  - Enumerations.json (4KB)
