Assessment: A local MCP server for a person's own Outlook or Gmail mailbox with careful defaults, a read-only scope profile, send allowlists, gated deletes and annotated tools, released weekly under Apache-2.0. It is pre-1.0 from one maintainer, Gmail lacks label and move support, and Gmail sign-in relies on UseJunior's hosted broker.

## Before you call it

1. Start with `get_mailbox_status`, then `list_emails` or `search_emails` before reading whole threads
2. Ask the person to set the send allowlist before planning any `send_email` or `reply_to_email`
3. Prefer `create_draft` and let the person send, unless they asked for sending
4. Expect NOT_SUPPORTED for label, flag, mark-read and move on Gmail, and don't request `gmail.modify` to work around it
5. Don't plan deletes; they need an operator environment variable and a caller flag

## Connect

```bash
npx -y email-agent-mcp
```

```bash
claude mcp add email-agent-mcp -- npx -y email-agent-mcp
