This is a reference design for a MCP server that hosts a web page that connects back to the server via sse and allows Claude to execute javascript on the page.

Add this server to your MCP-compatible client using the configuration below.

{
  "mcpServers": {
    "mcp_py_sse_browser_control": {
      "command": "python",
      "args": [
        "web_server.py"
      ]
    }
  }
}
