WHAT IT DOES

What batch_scrape does on Web Scraper MCP Server

AI agents invoke batch_scrape to trigger actions in Web Scraper MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.
