WHAT IT DOES

What generate_webmail_url does on 20i MCP Server

AI agents call generate_webmail_url to retrieve information from 20i MCP Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why generate_webmail_url is rated Low

This tool generates a URL (read/fetch operation with no data modification), but the URL produced is a single sign-on link granting authenticated access to a webmail account. Misuse could allow an attacker to gain access to email, hence medium severity despite being a Read operation.
