## Why send_mail is rated Medium

This tool creates and sends emails, which is a write operation that modifies external state (recipient mailboxes, sent folder). While not destructive in the sense of deletion, it is irreversible once sent and could be misused to send unauthorized communications, impersonate the user, or spam contacts. The high severity reflects potential for social engineering, credential compromise, or harassment.

From the tool's own definition: "Tool name is 'send_mail' and description states 'Compose and send an email via Apple Mail.' The verb 'send' combined with email composition indicates irreversible creation of a message that will be transmitted to recipients."

## Use case

AI agents use send_mail to create or update resources in AirMCP, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your AirMCP environment.

## Recommended policy (PolicyLayer)

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

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "send_mail": {
      "limits": [
        {
          "counter": "send_mail_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
