Emerging Standard: WebMCP
WebMCP (924 stars) proposes websites themselves as MCP servers — a W3C draft standard with early preview in Chrome 146. Instead of scraping, websites voluntarily expose structured data and actions through MCP.
Firefox Support
- firefox-devtools-mcp (56 stars) — WebDriver BiDi, DOM inspection, network monitoring

What's Missing
No Safari/WebKit MCP server. No cross-browser unified server. Limited mobile browser support. No browser extension development/testing MCP.
Bottom Line
Rating: 4.5/5 — Exceptional ecosystem with official Google backing, multiple high-adoption Chrome extensions, and a W3C standardization effort. The combination of Chrome DevTools (debugging/auditing), mcp-chrome (real browser sessions), and browser-tools-mcp (IDE integration) covers most browser automation needs.
