This fork of BrowserTools MCP extends the original browser monitoring toolset with Lighthouse-powered accessibility, performance, and SEO audits, leveraging Puppeteer for headless browser control.

Key Additions

Accessibility Audits: WCAG-compliant checks using Lighthouse.

The MCP server provides tools to run audits on the current page. Here are example queries you can use to trigger them:

Accessibility Audit (runAccessibilityAudit):
- "Are there any accessibility issues on this page?"
- "Run an accessibility audit."
- "Check if this page meets WCAG standards."
Performance Audit (runPerformanceAudit):
- "Why is this page loading so slowly?"
- "Check the performance of this page."
- "Run a performance audit."
SEO Audit (runSEOAudit):
- "How can I improve SEO for this page?"
- "Run an SEO audit."
- "Check SEO on this page."
