Usage

  1. Add MCP Browser Kit to your MCP Client:

    {
    "mcpServers": {
        "browser-kit": {
            "command": "npx",
            "args": ["@mcp-browser-kit/server@latest"]
        }
    }
}

    By default the server use stdio transport, alternatively you can use http transport:

    npx @mcp-browser-kit/server@latest --transport http
# optional flags (defaults shown):
#   --http-host 127.0.0.1
#   --http-port 21082

    Then point your MCP client at the URL instead of a command:

    {
    "mcpServers": {
        "browser-kit": {
            "url": "http://127.0.0.1:21082/mcp"
        }
    }
}

    Security: there's no auth yet, so --http-host defaults to 127.0.0.1 (loopback only). Only pass --http-host 0.0.0.0 (or a LAN address) if you understand that anyone who can reach that host/port can control your browser.

  2. Choose the right extension build for your browser:

    • Check the Compatibility table below to see which build (M2 or M3) is compatible with your browser
    • Note that M2 builds offer more functionality than M3 builds, so prefer M2 if your browser supports both

  3. Download the latest compatible build from The Latest Release.

  4. Load the extension into a compatible browser and enable it.

  5. Refresh open tabs to ensure extension scripts are loaded.

  6. Start messaging on your MCP Client:

    Use browser-kit, star the last open GitHub repo on my browser

  7. Optional, check User Notes for more information.
