WHAT IT DOES

What sf_send_email does on Salesforce Metadata Mcp

AI agents invoke sf_send_email to trigger actions in Salesforce Metadata Mcp. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

RISK

Why sf_send_email is rated High

This tool triggers an external operation (sending an email) that has real-world effects — recipients receive messages that cannot be unsent. While not financial or destructive to data, it executes an irreversible external action (email delivery) with significant blast radius if misused by an AI agent, e.g., sending spam, phishing, or sensitive data to unintended recipients.
