Search, extract, map, crawl, and research through Tavily hosted MCP, with Tavily skills. The default connection requires TAVILY_API_KEY; supports Hermes-managed OAuth through a native MCP override.

## Good to know before installing

Connects to Tavily's hosted MCP server at `mcp.tavily.com` and sends it the search queries, URLs and research prompts the agent issues, authenticated with `TAVILY_API_KEY` or a Hermes-managed Tavily OAuth sign-in.

From the plugin's catalog listing.

## How to install

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

```bash
hermes plugins install tavily-plugin
```

2. Said no? Turn it on later:

```bash
hermes plugins enable tavily-plugin
```

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
