## Why getMessage is rated Low

This tool only retrieves existing Gmail message data without creating, modifying, deleting, or executing anything. It has no side effects on the data or system. The blast radius of misuse is limited to unauthorized reading of message content, which is a confidentiality risk but not an operational or destructive one.

From the tool's own definition: "Tool fetches a single Gmail message by ID and returns message data (headers, body, attachments metadata). The verb 'fetches' and the retrieval-only nature with no modification capability indicate this is a data retrieval operation."

## Use case

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