• Bench Commands: Execute bench commands for development workflows
• App Management: Create, install, and manage Frappe apps
• API Endpoints: Generate custom API endpoints
• Database Operations: Run migrations and database management
• App Structure Analysis: Get detailed app directory structures

Installation

1. Clone or download this repository

2. Install dependencies:

   npm install
   

3. Build the server:

   npm run build
   

Configuration

Set the FRAPPE_PATH environment variable to point to your Frappe bench directory:
