  • web_extract_links_cremotemcp: Advanced link extraction and filtering
  • web_extract_table_cremotemcp: Structured table data extraction
  • web_extract_text_cremotemcp: Pattern-based text extraction

New Data Structures

  • MultipleExtractionResult: Structured results with error handling
  • LinksExtractionResult: Rich link information with metadata
  • TableExtractionResult: Table data with headers and structured format
  • TextExtractionResult: Text content with pattern matches

🚀 Key Benefits Achieved

For LLMs

  • Reduced Round Trips: Extract multiple data points in single API calls
  • Structured Data: Well-formatted JSON responses ready for processing
  • Rich Context: Comprehensive data extraction provides better understanding
  • Pattern Matching: Built-in regex support eliminates post-processing
  • Error Handling: Graceful handling of missing elements with detailed feedback

For Developers

  • Faster Automation: Bulk operations significantly speed up workflows
  • Better Data Quality: Structured responses with consistent formatting
  • Flexible Filtering: Advanced filtering options for precise data extraction
  • Comprehensive Coverage: Tools handle common extraction scenarios
  • Backward Compatibility: All existing tools continue to work unchanged

📊 Technical Implementation

Architecture Changes

All new functionality follows the established three-layer architecture:

  1. Daemon Layer (daemon/daemon.go):

    • Lines 620-703: Command handlers for new extraction commands
    • Lines 2542-2937: Implementation methods with timeout handling
  2. Client Layer (client/client.go):

    • Lines 824-857: New data structures for structured responses
    • Lines 989-1282: Client methods with parameter validation
  3. MCP Layer (mcp/main.go):

    • Lines 933-1199: MCP tool definitions with comprehensive schemas

Key Features Implemented

  • Batch Processing: Multiple selectors processed in single calls
  • Advanced Filtering: Regex patterns for href and text filtering
