CloudBrowser MCP Server

Give ChatGPT, Claude and your AI agents a real browser. CloudBrowser runs Chrome in the cloud. Your assistant opens a browser, navigates, reads pages, clicks, types and takes screenshots, and you can watch live or take over at any time.

  • Endpoint: https://mcp.cloudbrowser.ai (Streamable HTTP)
  • Auth: OAuth, sign in with your CloudBrowser account
  • Website: https://cloudbrowser.ai/mcp
  • Official MCP Registry: ai.cloudbrowser/mcp

What you can do

  • Open cloud Chrome browsers in your CloudBrowser account and connect to them.
  • Navigate, read page content, find elements, click, type, run scripts and take screenshots.
  • Save browser sessions and resume them later.
  • Start a remote desktop to watch the browser live or take over.
  • Detect CAPTCHAs. Login and verification walls stay with you.

Connect

The server uses OAuth. Your client opens a browser window, you sign in with your CloudBrowser account and approve access. You do not copy an API key.

Claude (claude.ai and Claude Desktop)

Open Settings → Connectors → Add custom connector, enter https://mcp.cloudbrowser.ai and select Connect.

Claude Code

Terminal
claude mcp add --transport http cloudbrowser https://mcp.cloudbrowser.ai

Then run /mcp in Claude Code and authenticate cloudbrowser.

Codex CLI

bash
codex mcp add cloudbrowser --url https://mcp.cloudbrowser.ai
codex mcp login cloudbrowser

Cursor

Add this to ~/.cursor/mcp.json:

config.json
{
  "mcpServers": {
    "cloudbrowser": { "url": "https://mcp.cloudbrowser.ai" }
  }
}

VS Code

bash
code --add-mcp '{"name":"cloudbrowser","type":"http","url":"https://mcp.cloudbrowser.ai"}'

Gemini CLI

bash
gemini mcp add --transport http cloudbrowser https://mcp.cloudbrowser.ai

ChatGPT and other clients

Add a custom connector (in ChatGPT, developer mode) with the URL https://mcp.cloudbrowser.ai. Any client that supports Streamable HTTP and MCP OAuth works.

Tools

The server advertises 20 tools. Your client gets the current schemas from tools/list.

  • Workspace: browser_workspace, resume_saved_session
  • Browser lifecycle: open_browser, close_browser, get_browsers, start_remote_desktop, stop_remote_desktop
  • Saved sessions: get_saved_sessions, remove_saved_session
  • Connections: connect_to_browser, disconnect_browser, get_connected_browsers
  • Page work: navigate_to_url, get_page_content, click_element, type_text, get_elements, take_screenshot, evaluate_script, detect_captcha

Authentication and account

OAuth 2.1 with PKCE and dynamic client registration. Sign in with your CloudBrowser account. Scope: browser:control (openid email optional). Developers can send their own account token instead: Authorization: Bearer <your CloudBrowser API token>. Keep the token in your client's secret settings, never in a prompt.

You need a CloudBrowser account. Browser usage follows your CloudBrowser plan.
