|
## Overview
|
|
|
|
Phase 4 of the cremote MCP enhancement plan has been successfully implemented, adding comprehensive page state and metadata capabilities to provide rich context for better debugging and monitoring.
|
|
|
|
## ✅ Implemented Features
|
|
|
|
### 1. Daemon Commands (daemon/daemon.go)
|
|
- ✅ `get-page-info` - Retrieves comprehensive page metadata and state information
|
|
- ✅ `get-viewport-info` - Gets viewport and scroll information
|
|
- ✅ `get-performance` - Retrieves page performance metrics
|
|
- ✅ `check-content` - Verifies specific content types and loading states
|
|
|
|
### 2. Data Structures
|
|
- ✅ `PageInfo` - Page metadata including title, URL, loading state, domain, protocol, charset, etc.
|
|
- ✅ `ViewportInfo` - Viewport dimensions, scroll position, device pixel ratio, orientation
|
|
- ✅ `PerformanceMetrics` - Load times, resource counts, memory usage, performance data
|
|
- ✅ `ContentCheck` - Content verification for images, scripts, styles, forms, links, iframes, errors
|
|
|
|
### 3. Client Methods (client/client.go)
|
|
- ✅ `GetPageInfo()` - Client method for page information retrieval
|
|
- ✅ `GetViewportInfo()` - Client method for viewport information
|
|
- ✅ `GetPerformance()` - Client method for performance metrics
|
|
- ✅ `CheckContent()` - Client method for content verification
|
|
|
|
### 4. MCP Tools (mcp/main.go)
|
|
- ✅ `web_page_info_cremotemcp` - MCP tool for page metadata
|
|
- ✅ `web_viewport_info_cremotemcp` - MCP tool for viewport information
|
|
- ✅ `web_performance_metrics_cremotemcp` - MCP tool for performance metrics
|
|
- ✅ `web_content_check_cremotemcp` - MCP tool for content verification
|
|
|
|

|
|
- **Loading States**: Complete detection of page loading and ready states
|
|
|
|
### Viewport Intelligence

|
|
- **Responsive Context**: Full viewport and scroll state information
|
|
|
|
### Performance Analysis
|
|
- **Load Metrics**: Navigation start, load event end, DOM content loaded
|
|
- **Paint Metrics**: First paint, first contentful paint timing
|
|
- **Resource Tracking**: Resource count, load times, DOM load times
|
|
- **Memory Usage**: JavaScript heap size information
|
|
