# Update Summary - Playwright MCP Server
## Changes Made Based on Updated Build Guide
This document summarizes the updates made to align with the new build guide requirements.
### ✅ What Was Updated
#### 1. User-Friendly Startup Messages (server.py)
**Before:**
```
Starting Playwright MCP Server v1.0.0
Debug mode: True
Server will run on http://0.0.0.0:8000
Inspector UI: http://0.0.0.0:8000/inspector
```
**After:**
```
============================================================
🚀 Playwright Automation Server v1.0.0
============================================================
📊 Inspector UI: http://localhost:8000/inspector
📄 API Docs: http://localhost:8000/docs
📋 OpenMCP: http://localhost:8000/openmcp.json
🔌 MCP Endpoint: http://localhost:8000/mcp
💡 Open http://localhost:8000/inspector in your browser
to test all 6 browser automation tools interactively
Press CTRL+C to stop the server
============================================================
```
**Why:** The new guide emphasizes user-friendliness by:
- Using `localhost` instead of `0.0.0.0` (more intuitive for non-technical users)
- Adding emojis for visual clarity
- Including clear instructions
- Showing all available endpoints at startup
#### 2. Enhanced README Documentation
**Updates:**
- Added step-by-step instructions for accessing Inspector UI
- Included visual output example showing the new startup message
- Added "How to use the Inspector" section with numbered steps
- Clarified that `0.0.0.0` should be replaced with `localhost` in browser
**Why:** Makes it easier for non-technical users to get started
#### 3. Configuration Header Updates (.env.example)
**Before:**
```env
# Server Configuration
```
**After:**
```env
# MCP Server Configuration
```
**Why:** Aligns with the terminology used in the updated build guide
### ✅ What Remains the Same (Already Correct)

- navigate(url, wait_until)
- click_element(selector)
- fill_input(selector, text)
- extract_text(selector)
- screenshot(path, full_page)
- get_page_info()
3. **Error Handling** ✅
- Already following debug-guardian patterns
- Standardized error response format
- Clear error types and suggestions
- No generic try/except blocks
4. **Browser Manager** ✅
- Singleton pattern implemented
- Lazy initialization
- Async lock for thread safety
- Graceful cleanup
- Crash recovery
5. **Code Quality** ✅
- Type hints on all functions
- Comprehensive docstrings
- Async/await throughout
- No hardcoded values
- Proper signal handlers
6. **Testing** ✅
- Unit tests (test_server.py)
- Integration tests (manual_test.py)
- Comprehensive test coverage
7. **Project Structure** ✅
