## Why gmail_search_messages is rated Low

This tool retrieves/queries email messages without creating, modifying, or deleting data. It has no side effects beyond data retrieval. However, severity is elevated to 'high' because email messages often contain sensitive personal information (passwords, tokens, private communications, financial details, PII), and an AI agent with uncontrolled search access could exfiltrate large volumes of such data.

From the tool's own definition: "Tool name 'gmail_search_messages' and description 'Search messages using Gmail search syntax' indicate retrieval of message data with no modification or deletion. The word 'Search' is a typical Read operation."

## Use case

AI agents call gmail_search_messages to retrieve information from Sage 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)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Sage MCP:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "gmail_search_messages": {}
  }
}
```
