Lighthouse MCP v0.1.0

Turn Lighthouse audits into coding-agent tasks

Lighthouse MCP is an npm-distributed MCP server that runs repeatable mobile and desktop Lighthouse audits and returns an implementation-ready report for coding agents.

Install

npx -y mcp-server-lighthouse

Highlights

• Mobile and desktop Performance, Accessibility, Best Practices, and SEO audits
• Fast mode with one run per profile and reliable mode with three-run medians
• Structured JSON plus equivalent Markdown
• At most 10 prioritized coding tasks
• Resource, DOM, and console evidence when Lighthouse provides it
• Deterministic suggested actions and measurable acceptance criteria
• Public-network URL policy to reduce SSRF risk

Examples

• JSON report: https://github.com/fullstackdegen/lighthouse-mcp/blob/main/examples/commalabs-fast-report.json
• Markdown report: https://github.com/fullstackdegen/lighthouse-mcp/blob/main/examples/commalabs-fast-report.md

Lighthouse results vary with browser version, hardware, network conditions, and page changes. The included CommaLabs report demonstrates the output shape, not a permanent score claim.

Requirements

• Node.js 20 or later
• Google Chrome or Chromium
