## Why search_emails is rated Low

This tool queries and retrieves email messages based on search criteria (KQL syntax). It has no side effects—no data is created, modified, deleted, or executed. The blast radius is minimal: an AI agent could exfiltrate email content, but cannot alter or destroy data. Categorized as Read per the definition: 'retrieves or queries data; no side effects.'

From the tool's own definition: "Tool name 'search_emails' and description stating it 'Search emails by keyword across all folders or within a specific folder' indicates retrieval of email data. No modification, deletion, or execution capabilities are mentioned."

Risk signals: Accepts freeform code/query input (query) · Accepts file system path (folder)

## Use case

AI agents call search_emails to retrieve information from Microsoft 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 Microsoft MCP:

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