# Connect v0

> Give v0 your Prefer data while it builds your site, with an MCP key.

Connected to Prefer, v0 can read the prompts you track, what the engines say about your brand, and your Action Center while it writes pages, so the pages answer what buyers actually ask.

**1. Create an MCP key**

In Prefer, open **Integrations → MCP** in the left navigation and create a key on the **Keys** tab, named for example "v0 for the main site". See [MCP keys](https://tryprefer.com/docs/ai-assistants/mcp-keys.md).

**2. Open MCPs in v0**

In v0, open the **+** menu in the prompt box and choose **MCPs**.

**3. Add Prefer as a custom server**

Add a custom server named **Prefer** with this URL:

```
https://mcp.tryprefer.com/mcp
```

**4. Add your key**

Choose **Bearer Token** as the authentication and paste your MCP key.

**5. Ask**

In a chat, ask v0 to use your Prefer data, for example "Use Prefer to find the questions buyers ask that our site doesn't answer, then draft a page for the first one."

> [!NOTE]
>
> v0 runs MCP tools according to its tool mode, so it may ask before it uses a Prefer tool. Prefer's tools only read data, so they never change anything in your workspace.
