Email for your agents through a self-hosted Agent Mail Gateway: the agent-mail skill teaches reading, searching, replying and forwarding mail, attachments, sending and answering calendar invitations, how to react when the gateway's pre-send review or the operator's policies stop a message, and prompt-injection rules for email content. Portable Agent Plugins v1 package (skills/ only, no code, no mcp.json): you connect the gateway yourself as a remote MCP server in mcp_servers with your own key; the gateway enforces per-mailbox sender/recipient allow lists.

## How to install

1. Install it. Hermes asks for any API keys it needs, then asks whether to turn it on.

```bash
hermes plugins install agent-mail-gateway
```

2. Said no? Turn it on later:

```bash
hermes plugins enable agent-mail-gateway
```

3. Restart Hermes so it loads the plugin.

Some plugins also need a sign-in or settings: see the official page. Memory plugins ask whether to become your memory provider instead. Steps follow the official plugins guide: https://hermes-agent.nousresearch.com/docs/user-guide/features/plugins
