## Why email_imap_unread is rated Low

This tool retrieves email data without side effects. It queries the mailbox state to return unread messages but does not create, modify, delete, or execute any operations. The blast radius of misuse is minimal—an agent could retrieve sensitive email content, but this is an information disclosure risk rather than a destructive or system-altering risk, making it a standard Read classification with low severity.

From the tool's own definition: "Tool name and description indicate it 'Fetch[es] unread emails' with no modification, deletion, or execution capability. The verb 'Fetch' and the constraint to 'directly from the configured Email channel mailbox' indicate read-only retrieval."

## Use case

AI agents call email_imap_unread to retrieve information from CoWork OS 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 CoWork OS:

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