# list_email_accounts

Lists all Mail.app accounts by name. Call this first to discover account names, then use list_emails(account=name) to fetch messages from a specific account. Much faster than querying all accounts at once.

## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",

    "name": "list_email_accounts",
    "arguments": {}

## Why list_email_accounts is rated Low

This tool retrieves account metadata from Mail.app without side effects. It is purely informational, enabling enumeration of available accounts to support subsequent read operations. No data is created, modified, deleted, or executed; it is a simple query operation.

From the tool's own definition: "Tool description explicitly states 'Lists all Mail.app accounts by name' with no modification or deletion capability. The tool is a discovery/query operation used to 'fetch messages' in a read-only manner."

## Use case

AI agents call list_email_accounts to retrieve information from Local 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 Local:

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