The ngrok AI Gateway as a Hermes model provider (`--provider ngrok`, or ngrok AI Gateway in `hermes model`): one access key for all your model providers, with failover. The model list comes live from your gateway, and gateway errors (unrouted model, access-policy and upstream-key failures, out of credit) map onto Hermes' fallback instead of a generic error.

## Good to know before installing

Registers one model provider at import and nothing else (no tools, hooks, commands or threads); chat requests and the model list go to https://gateway.ngrok.ai/v1 (or NGROK_AI_GATEWAY_BASE_URL) through Hermes' own client with NGROK_AI_GATEWAY_KEY, which Hermes reads; the plugin itself opens no connections, reads and writes no files and starts no processes.

From the plugin's catalog listing.

## How to install

1. Install it. Hermes asks for any API keys it needs (this one needs `NGROK_AI_GATEWAY_KEY`), then asks whether to turn it on.

```bash
hermes plugins install ngrok-ai-gateway
```

2. Said no? Turn it on later:

```bash
hermes plugins enable ngrok-ai-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
