Privacy-first agent email inboxes and workspace automation through hosted Mermail MCP. Portable Agent Plugins v1 package (mcp.json + skills/, seventeen skills bundled); authenticate with OAuth via `hermes mcp login mermail`. No credentials are stored in mcp.json.

## Good to know before installing

The bundled skills also expose Mermail's paybox wallet tools over the hosted MCP (x402 payments, xStocks trading, standing grants); the skills allow the agent to move funds without a same-turn confirmation when your message already states exact terms, so spending controls live on your Mermail account, not in Hermes.

From the plugin's catalog listing.

## 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 mermail
```

2. Said no? Turn it on later:

```bash
hermes plugins enable mermail
```

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
