scrape_url - Web Crawling with Search

Core Concept

mcp__plugin_kg_kodegen__scrape_url crawls websites, saves content as Markdown, and builds a Tantivy full-text search index. Uses an action-based interface with connection isolation and background execution support.

Actions

Key Parameters

Usage Examples

One-Step Search (Recommended)

Auto-crawls if index doesn't exist:

Copy{
  "action": "SEARCH",
  "url": "https://ratatui.rs",
  "crawl_id": 0,
  "query": "layout widgets"
}

Explicit Crawl

Copy{
  "action": "CRAWL",
  "crawl_id": 0,
  "url": "https://docs.rs/tokio"
}

Crawl with Limits

Copy{
  "action": "CRAWL",
  "url": "https://example.com/docs",
  "max_depth": 2,
  "limit": 50,
  "crawl_rate_rps": 1
}

Check Progress

Copy{
  "action": "READ",
  "crawl_id": 0
}

List Active Crawls

Copy{ "action": "LIST" }

Cancel Crawl

Copy{
  "action": "KILL",
  "crawl_id": 0
}

Workflows

Research Documentation

1. SEARCH with url and query (auto-crawls if needed)
2. Review results
3. Follow up with more specific queries

Full Site Crawl

1. CRAWL with url, max_depth, limit
2. Monitor with READ
3. Search with SEARCH action

Remember

• SEARCH with url auto-crawls if index missing - simplest approach
• Crawls are isolated by crawl_id - use different numbers for parallel crawls
• Rate limiting default is 2 req/sec - be respectful of servers
• Content saved as Markdown for easy reading
• Search index enables fast full-text queries
• Use READ to check on background crawls
• Timeout returns partial results - crawl continues in background
