## Why send-email is rated Medium

The tool creates and sends emails, which modifies the user's email account and communication state. While not destructive (emails can be recalled or deleted), and not financial, it is a Write operation that could have significant consequences if misused by an AI agent (e.g., sending emails to unintended recipients, composing misleading messages, or spamming).

From the tool's own definition: "Tool name is 'send-email' and description states 'Send new email or reply' — this creates new messages and modifies email threads by adding replies."

## Use case

AI agents use send-email to create or update resources in MCP Google Workspace, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your MCP Google Workspace environment.
