Scrape a single URL for specific keywords
AI agents call scrape_url to retrieve information from MCP Web Research Agent without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves content from a specified URL and filters it by keywords. It has no side effects on the target system—it reads publicly accessible data. Scraping is a passive data retrieval operation, classified as Read. Severity is low because misuse causes no damage: at worst, it fetches unwanted web pages. The confidence is high given the clear, unambiguous language in the tool name and description.
From the tool's definition Tool name 'scrape_url' combined with description 'Scrape a single URL for specific keywords' indicates data retrieval from a web page.
