Add powerful browser UI customization options to browser_configure tool:
- slowMo: Visual delays for demo recordings and training videos
- devtools: Auto-open Chrome DevTools for debugging sessions
- args: Custom browser launch arguments for themes and behavior
- chromiumSandbox: Sandbox control for container deployments
Key features:
• Dark mode interface support with --force-dark-mode
• Demo recording optimization with configurable action delays
• DevTools integration for development workflows
• Container deployment flexibility with sandbox control
• Comprehensive argument merging without duplicates
Includes complete documentation, testing suite, and production-ready
validation. Addresses user request for browser UI differentiation
and visual customization capabilities.
Technical changes:
- Enhanced Context.updateBrowserConfig() with UI parameter handling
- Extended configure tool schema with new Zod validations
- Fixed TypeScript compilation with skipLibCheck for upstream deps
- Added comprehensive test suite and documentation guide
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 dynamic snapshot configuration that MCP clients can control during
sessions without requiring server restarts or CLI changes.
New tool: browser_configure_snapshots
- Configure includeSnapshots, maxSnapshotTokens, differentialSnapshots at runtime
- Changes take effect immediately for subsequent tool calls
- Shows current settings when called with no parameters
- Provides helpful tips and usage guidance
Key improvements:
1. **Runtime Configuration**: Update snapshot behavior during active sessions
2. **Client Control**: MCP clients can adapt to different workflows dynamically
3. **Immediate Effect**: No server restart required - changes apply instantly
4. **State Tracking**: Context maintains current session configuration
5. **User Friendly**: Clear feedback on current settings and changes
Updated tool descriptions:
- All interactive tools now mention "configurable via browser_configure_snapshots"
- Removed references to CLI-only configuration
- Enhanced browser_snapshot description for explicit snapshots
Benefits for users:
🔄 Dynamic configuration without restarts
🎛️ Client-controlled snapshot behavior
📊 View current settings anytime
⚡ Instant configuration changes
🎯 Adapt settings per workflow/task
Example usage:
```json
{
"includeSnapshots": false,
"maxSnapshotTokens": 25000,
"differentialSnapshots": true
}
```
This transforms snapshot configuration from static CLI options into a flexible
session management system that adapts to client needs in real-time.
