## Why mail_read is rated Low

This tool retrieves email message content by identifier. It performs a read-only operation on existing data with no creation, modification, deletion, or execution of code. The blast radius is minimal as it only exposes message content that the user likely already has access to through the Mail application.

From the tool's own definition: "Tool name is 'mail_read' and description states 'Read a Mail message by id.' The verb 'read' and the action of retrieving a specific message indicate a query operation with no side effects."

## Use case

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

## Recommended policy (PolicyLayer)

```json

  "version": "1",
