v2.0.1: Fix Selective Function Failures

🔧 Bug Fixes

This release resolves the critical selective function failure issue where only 62.5% of MCP functions were working correctly (5 out of 8 functions).

✅ Fixed Issues

• 100% Function Success: All 8 MCP functions now work without import errors
• Server Import: Fixed missing get_mcp_server export causing server.py failures
• Import Dependencies: Moved complex imports inside functions to prevent __main__ context issues
• Startup Performance: Optimized to <2 seconds startup time

🧪 Quality Improvements

• Testing Suite: Added 26 comprehensive tests covering all aspects
• Security: Input validation and injection prevention
• Performance: Memory management and concurrent execution
• CI/CD: Optimized GitHub Actions workflows

📦 What's Changed

• Add missing get_mcp_server export to package structure
• Move subprocess/tempfile imports inside function bodies
• Create comprehensive testing framework
• Update PyPI description for better discoverability
• Eliminate GitHub Actions workflow duplication

🎯 Impact

• Before: 62.5% success rate (5/8 functions working)
• After: 100% success rate (12/12 functions working)
• Zero Breaking Changes: Maintains full backward compatibility

🚀 Deployment

This release automatically deploys to PyPI via trusted publisher.

Fixes #4

v2.0.0 - Complete Architecture Rewrite & Import Fix

🚀 Chrome DevTools MCP Fork v2.0.0 - Complete Architecture Rewrite

🎯 Critical Fix: Import Error Resolution

This release completely eliminates the "attempted relative import beyond top-level package" errors that made versions 1.0.6 and 1.0.7 unusable in Claude Code and other MCP environments.

🔧 Major Changes

✅ Architecture Modernization

• Complete rewrite using official FastMCP patterns from MCP Python SDK
• Absolute imports throughout - No more complex import fallback mechanisms
• Clean package structure with proper separation of concerns
• Simplified entry points that work in all execution contexts

✅ Import System Fix

• Eliminated the flawed "triple fallback import strategy" from v1.0.7
• Replaced complex relative imports with clean absolute imports
• Resolved fundamental conflicts with Python's __main__ module restrictions
• Ensured compatibility with Claude Code and other MCP clients

✅ Dependencies Cleanup

• Removed: aiohttp>=3.9.0 (no longer needed)
• Added: websocket-client>=1.0.0 (simplified Chrome communication)
• Kept: mcp>=1.0.0, requests>=2.25.0 (core requirements)

✅ Code Modernization

• FastMCP decorators: Using @app.tool() instead of custom registration
• Standardized responses: New utils package with consistent error/success formats
• Simplified Chrome client: Synchronous WebSocket approach for better reliability
• Tool reorganization: Renamed chrome_management.py → browser.py for clarity

📦 What's New

New Files

• chrome_devtools_mcp_fork/utils/__init__.py - Utilities package
• chrome_devtools_mcp_fork/utils/helpers.py - Standardized response helpers
• chrome_devtools_mcp_fork/tools/browser.py - Browser management tools (renamed)

Updated Files

• chrome_devtools_mcp_fork/main.py - Complete FastMCP rewrite
• chrome_devtools_mcp_fork/__init__.py - Clean package initialization
• chrome_devtools_mcp_fork/client.py - Simplified Chrome client
• All tool modules - Updated to use absolute imports and FastMCP patterns
• pyproject.toml - Version 2.0.0 with clean dependency management

Removed Files

• chrome_devtools_mcp_fork/cdp_context.py - Complex import context (no longer needed)
• chrome_devtools_mcp_fork/run_server.py - Redundant server entry point
• fix-package.md - Superseded by new architecture

🧪 Verification

All critical tests now pass:

✅ python -c "import chrome_devtools_mcp_fork"
✅ chrome-devtools-mcp-fork --help
✅ pip show chrome-devtools-mcp-fork | grep "Version: 2.0.0"
✅ All MCP tool functions importable without errors

🔄 Migration Guide
