Tapsite
If you need an AI agent to understand a website's internals rather than just click through it, this is the server to reach for. It exposes 55 tools across design system extraction, accessibility auditing, tech stack detection, and custom data scraping with CSS selectors, XPath, or regex. You can pull structured design tokens (colors, fonts, spacing, shadows), run WCAG contrast checks, diff two sites side by side, detect GraphQL endpoints, or crawl behind login walls with persistent sessions and anti-bot handling. Everything returns as structured JSON that agents can reason about, and it works with Playwright under the hood for reliable rendering.

tapsite
The MCP server for web intelligence extraction. 55 tools that give AI agents the ability to understand websites — not just drive a browser, but extract structured intelligence about design systems, accessibility, performance, content, and more.
Other MCP browser tools let agents click buttons. tapsite lets agents extract a complete color palette, audit WCAG contrast ratios, diff two sites' design tokens, detect tech stacks, or pull structured data with custom CSS/XPath/regex selectors — all as structured JSON that agents can reason about.
