danielsogl/lighthouse-mcp-server

Implements MCP's stdio transport protocol to integrate with LLM clients like VS Code, Cursor, and Claude Desktop, with support for persistent Chrome profiles that preserve authenticated sessions across audit runs. Exposes granular Lighthouse results as structured tools for accessing specific metrics (Core Web Vitals, accessibility scores, security checks) rather than raw audit data, enabling agents to parse and act on findings programmatically. Supports both headless and headed Chrome modes with optional remote debugging attachment, allowing audits against authenticated or dynamic content.
