# What is GoogleAgent-Mariner?

A community-reported token for a Google browsing agent, listed alongside GoogleAgent-URLContext and GoogleAgent-Shopping. It also appears in amazon.com's robots.txt.

- **robots.txt token**: `GoogleAgent-Mariner`
- **Operator**: Google
- **Purpose**: Agents
- **Obeys robots.txt**: The operator does not say.
- **Documented by operator**: No. The token is known only from community lists such as ai.robots.txt.

Google's official crawler pages do not list it, so its robots.txt behaviour is unknown.

## Block GoogleAgent-Mariner from your whole site

`robots.txt`

```
User-agent: GoogleAgent-Mariner
Disallow: /
```

## Allow it, but keep private paths out

`robots.txt`

```
User-agent: GoogleAgent-Mariner
Allow: /
Disallow: /admin/
```

This bot fetches pages for a person, or for an agent acting on one's behalf. Several operators say robots.txt may not apply to such requests, so check the line above and enforce at your firewall if it matters.
