Browser Extension MCP Servers — Chrome DevTools, Firefox, WebMCP, and 15+ Servers Reviewed

At a glance: 15+ browser extension MCP servers across 5 subcategories. Chrome DevTools official (28,700 stars), three Chrome extensions over 6,000 stars each, WebMCP emerging as W3C browser-native standard. Rating: 4.5/5.

The Big Players

Chrome DevTools MCP (Official Google) — 28,700 stars

The official MCP server from Google's Chrome DevTools team. Performance tracing, Lighthouse audits, memory profiling, Puppeteer automation, accessibility debugging. Works with Gemini, Claude, Cursor, Copilot.

mcp-chrome — 10,800 stars

Chrome extension that uses your actual daily browser — inherits login state, cookies, bookmarks. Tab management, semantic search, DOM interaction, screenshots. Avoids bot detection because it IS your real browser.

browser-tools-mcp — 7,100 stars

Development-focused bridge between IDE and browser. Real-time console capture, network monitoring, WCAG accessibility audits, Lighthouse performance analysis, SEO evaluation. Auto-paste findings to IDE.

BrowserMCP — 6,100 stars

Chrome extension for local automation with real browser fingerprint. No bot detection issues. Apache 2.0 license.

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
  • browser-control-mcp (250 stars) — security-focused with audit log and domain consent
  • firefox-mcp-server — 28 tools, multi-session management, WebSocket 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.
