# v0

> Connect the UseAgents MCP server to v0 by Vercel using the web interface.

Connect UseAgents to v0 so the AI assistant can discover verified developer tools from the registry while generating UI and code.

<Note>
  UseAgents is **currently free** during our public beta. No API key is required. Requests are subject to [rate limits](/api-reference/rate-limit).
</Note>

## Connect via the v0 web UI

v0 supports MCP connections directly from its web interface.

1. Go to [v0.dev](https://v0.dev) and sign in.
2. In the prompt form, click the **Add MCP** button, or navigate to **MCP Connections** in settings.
3. Paste the server URL:

```text theme={null}
https://mcp.useagents.site/mcp
```

4. Set the authentication method to **No Auth**.
5. Save the connection.

## Verify the connection

1. Start a new v0 conversation.
2. Ask v0 to search for a tool — for example: *"Use UseAgents to find a TypeScript SDK for Stripe."*
3. Confirm you receive structured tool results from the UseAgents registry.

## Troubleshooting

* **MCP option not visible**: MCP support on v0 may require a specific plan. Check the latest v0 documentation.
* **Connection failed**: Verify that the URL is exactly `https://mcp.useagents.site/mcp` and the auth method is set to **No Auth**.
