2. Select the `Configure` tab and click `Configure MCP Servers`. This should open `cline_mcp_settings.json`.

3. Update `cline_mcp_settings.json`

```
{
  "mcpServers": {
    "Ref": {
      "command": "npx",
      "args": ["ref-tools-mcp@latest"],
      "env": {
        "REF_API_KEY": "<YOUR_API_KEY>"
      }
    }
  }
}
```

## Verify

Open a new chat with Cline and run the following prompt.

```
what is ref tools mcp, search the docs with ref

This should results in a `ref_search_documentation` tool call.
