WHAT IT DOES

What create_email_forwarder does on 20i MCP Server

AI agents use create_email_forwarder to create or update resources in 20i MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your 20i MCP Server environment.

RISK

Why create_email_forwarder is rated Medium

This tool creates a new email forwarder, which is a reversible modification to hosting package settings. It does not execute arbitrary code, delete data, or move money. The blast radius is medium because misconfigured email forwarders could disrupt mail delivery or create security issues (e.g., forwarding to unintended recipients), but the action itself is not destructive and can be undone by deleting the forwarder.

From the tool's definition Tool name 'create_email_forwarder' and description 'Create an email forwarder for a hosting package' indicate a creation operation that modifies email configuration.
