WHAT IT DOES

What convert_url does on ContextForge MCP Gateway

AI agents call convert_url to retrieve information from ContextForge MCP Gateway without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why convert_url is rated Low

The tool retrieves content from a URL and converts it to markdown. This is fundamentally a read/fetch operation with no persistent side effects on the server. However, it does make outbound network requests to arbitrary URLs, which could be abused for SSRF attacks or to exfiltrate data via URL parameters, warranting a medium severity rating.
