cntx-ui

Minimal file bundling and tagging tool for AI development with web interface.

Features

• File bundling and organization for AI development workflows
• Web-based UI for managing bundles and configurations
• Model Context Protocol (MCP) server for AI integration
• Hidden files management
• Cursor rules integration
• WebSocket-based real-time updates
• CLI tools for automation

Installation

Global Installation (Recommended)

npm install -g cntx-ui

Local Development Installation

git clone https://github.com/nothingdao/cntx-ui.git
cd cntx-ui
npm install

Usage

Initialize a Project

# Initialize cntx-ui in your project
cntx-ui init

# Start the web interface
cntx-ui watch

# Visit http://localhost:3333 to access the web UI

CLI Commands

# Generate bundles
cntx-ui bundle <name>

# Check project status
cntx-ui status

# Start web server on custom port
cntx-ui watch [port]

# Start web server with MCP status tracking
cntx-ui watch --with-mcp

# Start MCP server for AI integration
cntx-ui mcp

# Add project to Claude Desktop MCP configuration
cntx-ui setup-mcp

MCP Integration

cntx-ui can function as an MCP (Model Context Protocol) server, providing AI tools with direct access to your project bundles:

# Start MCP server
cntx-ui mcp

Available MCP Resources:

• cntx://bundle/<name> - Access any bundle as XML content
• cntx://file/<path> - Access individual project files

Available MCP Tools:

• list_bundles - List all available bundles
• get_bundle - Retrieve specific bundle content
• generate_bundle - Regenerate a bundle
• get_file_tree - Get project file structure
• get_project_status - Get current project status

Development

Prerequisites

• Node.js >= 18.0.0
• npm

Setup Development Environment

1. Clone and install dependencies:

   git clone https://github.com/nothingdao/cntx-ui.git
   cd cntx-ui
   npm install
   

2. Install web dependencies:

   cd web
   npm install
   cd ..
   

Development Workflow

Running in Development Mode

1. Start the backend server:

   npm run dev
   

2. Start the frontend development server:

   npm run dev:web
   

   The web interface will be available at http://localhost:5173 (Vite dev server)

Building the Project

1. Build web interface only:

   npm run build:web
   

2. Build entire project:

   npm run build
   

3. Automated build with validation:

   ./build.sh

MCP Server Setup

Quick Setup with setup-mcp Command

The easiest way to configure cntx-ui for Claude Desktop:

# Navigate to your project directory
cd /path/to/your/project

# Initialize cntx-ui if not already done
cntx-ui init

# Add this project to Claude Desktop MCP configuration
cntx-ui setup-mcp

This automatically adds your project to Claude Desktop's configuration file and allows you to work with multiple projects simultaneously.

Claude Desktop Integration

Multi-Project Setup (Recommended)

You can use cntx-ui across multiple projects by running setup-mcp in each project directory:

# Project 1
cd /Users/you/project1
cntx-ui setup-mcp

# Project 2  
cd /Users/you/project2
cntx-ui setup-mcp

This creates entries in your Claude Desktop config (~/Library/Application Support/Claude/claude_desktop_config.json):

{
  "mcpServers": {
    "cntx-ui-project1": {
      "command": "sh",
      "args": ["-c", "cd /Users/you/project1 && node /path/to/cntx-ui/bin/cntx-ui.js mcp"],
      "cwd": "/Users/you/project1"
    },
    "cntx-ui-project2": {
      "command": "sh", 
      "args": ["-c", "cd /Users/you/project2 && node /path/to/cntx-ui/bin/cntx-ui.js mcp"],
      "cwd": "/Users/you/project2"
    }
  }
}

Manual Configuration

For manual setup, add to your Claude Desktop configuration:

{
  "mcpServers": {
    "cntx-ui-projectname": {
      "command": "sh",
      "args": ["-c", "cd /path/to/your/project && cntx-ui mcp"],
      "cwd": "/path/to/your/project"
    }
  }
}

Other MCP Clients

For other MCP-compatible clients, use:

• Command: cntx-ui mcp
• Transport: stdio
• Working Directory: Your project root

MCP Workflow

1. Setup: Run cntx-ui setup-mcp in each project you want to use with Claude Desktop
2. Visual Configuration: Use cntx-ui watch to configure bundles via web UI
3. AI Integration: AI clients connect via MCP to access bundles across all configured projects
4. Real-time Updates: Changes in web UI immediately available to AI tools
5. Multi-Project: Claude Desktop can access bundles from all configured projects simultaneously

Testing

Local Testing

1. Run automated test suite:

   ./test-local.sh
   

2. Manual testing:

   # Build and pack
   npm run build
   npm pack
   
   # Install globally for testing
   npm install -g ./cntx-ui-*.tgz
   
   # Test in a new project
   mkdir test-project && cd test-project
   cntx-ui init
   cntx-ui watch
   

Test Coverage

The test suite covers:

• Project initialization
• Bundle generation
• Web server functionality
• API endpoints
• File management operations

Publishing

Prerequisites for Publishing

• npm account with publish permissions
• Clean git working directory
• All tests passing

Publishing Steps

1. Update version:

   npm version patch  # or minor/major
   

2. Build and validate:

   ./build.sh
   

3. Test locally:

   ./test-local.sh
   

4. Publish to npm:

   # Stable release
   npm publish
   
   # Beta release

Automated Publishing Workflow

Use the build script for a complete workflow:

./build.sh
# Follow prompts for local testing
# If tests pass, run: npm publish
