FAQ from Lighthouse MCP Server

What are the runtime requirements?

Node.js 22.0.0 or newer and Chrome/Chromium (automatically managed by Lighthouse).

How do I use authenticated sessions with cookies and local storage?

Launch with a persistent Chrome profile using --profile-path <path> and --no-headless. Profile mode disables storage reset so sessions persist across audits.

Can I attach to an existing Chrome instance?

Yes, use --chrome-port <port> or --remote-debugging-port <port> to connect to a Chrome instance launched with remote debugging enabled. Pass --profile-path to preserve storage.

What tools are available for web analysis?

Tools include run_audit, get_performance_score, get_core_web_vitals, get_accessibility_score, get_seo_analysis, check_performance_budget, analyze_resources, find_unused_javascript, and get_security_audit.

Does the server support WSL2?

Yes, set the Chrome binary path explicitly via --chrome-path or the CHROME_PATH environment variable to select the correct Linux binary.
