Description

Webtools MCP Server is a toolkit-style MCP server that uses Puppeteer (bundled Chrome) to render pages and provide tools for content extraction, screenshots, debug logging, network and performance analysis, and Lighthouse audits. It supports device emulation, proxy and SSL options, advanced performance tracing (layout thrashing, memory, JS timelines), and configurable network conditions. The server is intended for development, research, and automated agents that need detailed, actionable web diagnostics and content extraction rather than production scraping at scale. It also includes token-usage presets to enable smaller MCP prompt payloads by loading only the tools you need.
