Best for
  • Developers experimenting with browser automation.
  • Users who want AI browser capabilities in Chrome, Edge, or Electron.
  • Users who need access to Composio integrations.
  • Developers who need browser automation from Claude Desktop, VS Code, and similar clients
  • Users doing web testing and scraping
Not for
  • Users seeking a documented MCP server transport or standard client configuration.
  • Users unwilling to provide a Google API key.
  • Production environments requiring confirmed official maintenance or a known license.
  • Environments requiring strict sandboxing that disallow AI-controlled browsers
  • Claude Desktop users needing HTTP/SSE mode (Claude Desktop currently requires stdio mode)
Required permissions
  • Requires browser-extension access to perform screenshots, clicks, typing, scrolling, and navigation on web pages.
  • Requires a Google API key; Tool Router mode additionally requires an optional Composio API key.
  • May access user-controlled web content and data from configured integrations.
  • Runs real browsers (Chromium, Firefox, WebKit) locally
  • Automatically downloads and installs browser binaries on first use
  • Writes log files to ~/playwright-mcp-server.log
  • Binds a local port in HTTP mode (default 8931)
Risks and side effects
  • Browser automation may perform sensitive actions; the project provides confirmation dialogs for actions such as checkout and payment.
  • The handling risk for API keys, web content, and integration data depends on configuration and usage.
  • The license is listed as unknown, so specific commercial or redistribution rights should not be assumed.
  • AI can execute JavaScript in a real browser, potentially accessing and manipulating sensitive web content
  • Automatic browser downloads consume disk space and bandwidth
  • HTTP mode binds to localhost only; exposing it via SSH tunnels still requires caution
Supported clientsClaude Desktop, Claude Code, Cline, Cursor, VS Code
