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.
- Accessibility Audits: WCAG-compliant checks using Lighthouse.
- Performance Audits: Analyze page load and runtime efficiency.
- SEO Audits: Assess on-page SEO factors and suggest improvements.
- Puppeteer Integration: Enables reliable, headless browser audits.
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."
- Follow the Browser Tools installation guide
- To try the new tools, make sure to stand in the current tab (that you want to scan) with the Browser tools extension active
