## Why list_emails is rated Low

This tool queries and returns email messages from a folder, a read-only operation with no side effects on data. Severity is medium rather than low because email can contain sensitive personal or business information (PII, trade secrets, financial data), creating moderate risk if an AI agent misuses access to list emails from someone else's mailbox or exposes contents to unauthorized parties.

From the tool's own definition: "'List emails from a mailbox folder' — retrieves email data without modifying or deleting it. The verb 'list' is explicitly retrieval-based."

Risk signals: Accepts file system path (folder)

## Use case

AI agents call list_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": {
    "list_emails": {}
  }
}
```
