Can I see the browser window while Claude is using it?

No, the servers are configured with the --headless flag, which means the browser runs in the background without a visible GUI for maximum efficiency.

What should I do if I see a 'Browser already running' error?

This usually indicates a stale lock. You can resolve it by running 'rm -f ~/.cache/chrome-devtools-mcp/chrome-profile/Singleton*' in your terminal.

Why does this skill use five different servers?

It allows multiple parallel agents to work simultaneously without conflicting on the same 'selected page,' effectively preventing race conditions during complex tasks.

Does it support parallel agents automatically?

The skill provides the infrastructure for parallel agents; the user or agent should check server availability in order (1 through 5) to ensure each agent uses a free instance.

How do I prevent the browser from consuming too much memory?

You should follow the cleanup protocol by using the close_page command for all indices except index 0 (about:blank) once your task is complete.

Automatización de Navegadores

Enables high-performance browser automation and web interaction using multiple parallel Chrome instances for complex multi-agent workflows.

This skill integrates the Chrome DevTools Protocol into Claude Code, allowing the AI to navigate websites, capture screenshots, and manipulate web pages with precision. It is uniquely architected with five parallel MCP servers to prevent race conditions during multi-agent tasks, ensuring each agent operates within its own isolated browser environment. It includes sophisticated logic for server availability checks, headless operation for speed, and manual cleanup procedures to optimize system resources while performing web scraping, testing, or automated research.
