Enables on-the-fly proxy switching without restarting MCP server, allowing
users to dynamically set or clear proxy settings during browser sessions.
Changes:
- Add proxyServer and proxyBypass parameters to updateBrowserConfig method
- Implement proxy set/clear logic with proper validation for empty strings
- Expose proxy configuration through browser_configure tool interface
- Update auto-generated documentation with proxy parameter descriptions
Tested with SOCKS5 proxy, verified IP changes when proxy is enabled/disabled.
Add key feature highlighting the new multi-client identification system with debug toolbar and code injection capabilities for managing parallel MCP clients.
Video Recording Fixes:
- Fix session persistence issues where recording state was lost between tool calls
- Improve page video object handling by triggering navigation when needed
- Add browser_reveal_artifact_paths tool to show exact file locations
- Enhance browser_recording_status with detailed debugging info and file listings
- Add clearVideoRecordingState() method for proper state management
- Keep recording config available for debugging until new session starts
Request Monitoring System:
- Add comprehensive RequestInterceptor class for HTTP traffic capture
- Implement 5 new MCP tools for request monitoring and analysis
- Support multiple export formats: JSON, HAR, CSV, and summary reports
- Add filtering by domain, method, status codes, and response timing
- Integrate with artifact storage for organized session-based file management
- Enhance browser_network_requests with rich intercepted data
Additional Improvements:
- Add getBaseDirectory/getSessionDirectory methods to ArtifactManager
- Fix floating promise in tab.ts extension console message polling
- Add debug script for comprehensive video recording workflow testing
- Update README with new tool documentation
Resolves video recording workflow issues and adds powerful HTTP traffic
analysis capabilities for web application debugging and security testing.
- Add browser_set_offline tool documentation
- Document offline parameter in browser_configure tool
- Auto-generated tool documentation now includes all new features
Major enhancements to browser automation and debugging capabilities:
**Console Capture Features:**
- Add console output file option (CLI, env var, session config)
- Enhanced CDP console capture for service worker messages
- Browser-level security warnings and mixed content errors
- Network failure and loading error capture
- All console contexts written to structured log files
- Chrome extension for comprehensive console message interception
**Offline Mode Support:**
- Add browser_set_offline tool for DevTools-equivalent offline mode
- Integrate offline mode into browser_configure tool
- Support for testing network failure scenarios and service worker behavior
**Extension Management:**
- Improved extension installation messaging about session persistence
- Console capture extension with debugger API access
- Clear communication about extension lifecycle to MCP clients
**Technical Implementation:**
- CDP session management across multiple domains (Runtime, Network, Security, Log)
- Service worker context console message interception
- Browser context factory integration for offline mode
- Pure Chromium configuration for optimal extension support
All features provide MCP clients with powerful debugging capabilities
equivalent to Chrome DevTools console and offline functionality.
Implements comprehensive solution for browser_click and other interactive tools
returning massive responses (37K+ tokens) due to full page snapshots.
Features implemented:
1. **Snapshot size limits** (--max-snapshot-tokens, default 10k)
- Automatically truncates large snapshots with helpful messages
- Preserves essential info (URL, title, errors) when truncating
- Shows exact token counts and configuration suggestions
2. **Optional snapshots** (--no-snapshots)
- Disables automatic snapshots after interactive operations
- browser_snapshot tool always works for explicit snapshots
- Maintains backward compatibility (snapshots enabled by default)
3. **Differential snapshots** (--differential-snapshots)
- Shows only changes since last snapshot instead of full page
- Tracks URL, title, DOM structure, and console activity
- Significantly reduces token usage for incremental operations
4. **Enhanced tool descriptions**
- All interactive tools now document snapshot behavior
- Clear guidance on when snapshots are included/excluded
- Helpful suggestions for users experiencing token limits
Configuration options:
- CLI: --no-snapshots, --max-snapshot-tokens N, --differential-snapshots
- ENV: PLAYWRIGHT_MCP_INCLUDE_SNAPSHOTS, PLAYWRIGHT_MCP_MAX_SNAPSHOT_TOKENS, etc.
- Config file: includeSnapshots, maxSnapshotTokens, differentialSnapshots
Fixes token overflow errors while providing users full control over
snapshot behavior and response sizes.
