Can fetch pages, click elements, fill forms, and extract content. Opens real browser for user authentication, then automates interactions and extraction. DO NOT use for simple HTML pages that work with regular HTTP GET requests."

概览

What is MCP Browser?

MCP Browser is an MCP (Model Context Protocol) server that gives AI assistants (Claude, Copilot) the ability to browse web pages using your real Chrome or Edge browser session. It handles authentication, CAPTCHAs, anti-bot protection, and JavaScript-heavy sites by leveraging your existing logged-in session rather than using headless automation.

How to use MCP Browser?

Install via the VS Code Marketplace extension (one‑click), a single Claude Code command (claude mcp add mcpbrowser), manual configuration in Claude Desktop’s claude_desktop_config.json, or the npx -y mcpbrowser@latest command. After setup, the AI can invoke tools like fetch_webpage, click_element, type_text, get_current_html, and close_tab to interact with web pages.

Key features of MCP Browser

Uses your own Chrome/Edge browser (not headless).
Authenticates once – AI inherits your session.
Handles SSO, CAPTCHAs, Cloudflare, and SPAs.
Provides tools for navigation, clicking, typing, and content extraction.
Reduces page size by ~90% when removeUnnecessaryHTML is enabled.
Works with Claude Desktop, Claude Code, GitHub Copilot, and any MCP host.

Use cases of MCP Browser

Automating login flows on sites with corporate SSO or multi‑factor authentication.
Extracting data from authenticated dashboards (e.g., Azure Portal, admin panels).
Interacting with JavaScript‑heavy single‑page applications.
Resetting session state by closing a tab for a fresh login.
Performing multi‑step workflows that require button clicks and form fills.

常见问题

What are the requirements to use MCP Browser?

You need Node.js 18+ and either Chrome or Edge browser installed on your machine.

How does MCP Browser connect to my browser?

It launches your local Chrome or Edge in a managed mode and reuses your existing user data directory, so cookies and authentication persist across sessions.

Which AI assistants can use MCP Browser?

Any MCP‑compatible host, including Claude Desktop, Claude Code (CLI), and GitHub Copilot. The VS Code extension auto‑configures it for Copilot.

Can MCP Browser interact with pages after logging in?

Yes. Load the login page with `fetch_webpage`, then use `type_text` and `click_element` to log in. The session stays open, and you can call `get_current_html` or further tools on the same domain without re‑authenticating.

How do I clear an authenticated session?

Use `close_tab` with the page’s URL. This closes the associated browser tab and forces a fresh session the next time that domain is visited.
