## Description

DataFetch is a secure web content fetching server that provides sandboxed access to web pages without JavaScript execution, featuring comprehensive security protections including URL validation, path traversal prevention, prompt injection detection, and automatic cookie banner removal. The implementation uses aiohttp for HTTP operations with proper cookie handling, BeautifulSoup for HTML parsing and sanitization, and operates within a configurable sandboxed working directory to prevent file system access outside designated areas. It exposes five core tools for fetching webpages in multiple formats (markdown, text, HTML), extracting and categorizing links, safely downloading files with size limits, retrieving structured metadata including Open Graph and Twitter Cards, and checking URL status.
