}fetch_htmlFetches a website's content and returns it as raw HTML.
Fetching arbitrary URLs can expose the system to malicious HTML.
fetch_jsonFetches a JSON file from a given URL.
Fetching arbitrary URLs can expose the system to malicious JSON payloads.
fetch_txtFetches a website and returns its content as plain text, stripping HTML tags.
Fetching arbitrary URLs can expose the system to potentially harmful content, even after stripping HTML.
fetch_markdownFetches a website and converts its content to Markdown format.
Fetching arbitrary URLs can expose the system to malicious HTML that, when converted to Markdown, may still pose a risk.
The Fetch server is generally safe for read-only operations. However, the risk of SSRF and fetching malicious content exists if URLs are not carefully validated. Implementing URL validation and rate limiting would improve safety.
