What is Browser MCP?

Browser MCP gives AI agents (Claude Code, Cursor, VS Code agent mode) control of your real, logged-in Chrome browser — with your cookies, sessions, and 2FA — so it works on CAPTCHA, 2FA, and anti-bot sites where headless tools get blocked. It is built for developers who need to automate web tasks that require an authenticated human browser.

How to use Browser MCP?

Install the MCP server by running npx @agent360/browser-mcp install, then load the Chrome extension from ~/.browser-mcp/extension/ via chrome://extensions with Developer mode enabled. Alternatively, install from the Chrome Web Store and run npx @agent360/browser-mcp install --skip-extension to configure Claude Code.

FAQ from Browser MCP

How does Browser MCP differ from Playwright MCP?

Browser MCP uses your real Chrome with existing logins and cookies, supports multi-session with tab groups, includes human-in-the-loop tools, and has built-in provider integrations. Playwright MCP uses a headless browser that must log in every time and has no human fallback.

How does Browser MCP handle CAPTCHAs?

It auto-detects reCAPTCHA v2/v3, hCaptcha, Turnstile, and FunCaptcha. It can auto-click the checkbox (~80% success with Google login), use AI vision for grid selection, or fall back to asking the human via an overlay dialog.

Is Browser MCP free and does it send data anywhere?

Yes, it is MIT licensed and free. All processing is local — nothing leaves your machine. The extension connects to the MCP server via WebSocket on localhost.

How do I update Browser MCP?

The MCP server updates automatically via npx @agent360/browser-mcp@latest. The extension updates automatically if installed from the Chrome Web Store; if loaded unpacked, re-run npx @agent360/browser-mcp install and reload the extension in Chrome.

What are the runtime requirements?

You need Chrome (or a Chromium-based browser) and Node.js to run the npx command. No additional authentication is required — it uses your existing Chrome session.
