Restart Claude Code to have the MCP server and skills load (check with `/skills`).

To connect the plugin to a Chrome instance that is already running with remote debugging, set the plugin's `browserUrl` option in your Claude Code settings:

```json
{
"pluginConfigs": {
"chrome-devtools-mcp@claude-plugins-official": {
"options": {
"browserUrl": "http://127.0.0.1:9222"
}
}
}
}
```

Leave `browserUrl` blank to use the default behavior where Chrome DevTools MCP launches Chrome automatically.

> [!TIP]
> If the plugin installation fails with a `Failed to clone repository` error (e.g., HTTPS connectivity issues behind a corporate firewall), see the [troubleshooting guide](./docs/troubleshooting.md#claude-code-plugin-installation-fails-with-failed-to-clone-repository) for workarounds, or use the CLI installation method above instead.
