sphakanin/dwb-serena-tunnel-starter ? reverse-engineered prompt

Build me a small Windows starter kit that makes it easy to connect ChatGPT to a local Serena MCP server through an OpenAI Secure MCP Tunnel.

I want simple double click scripts for first time setup, configuration, and starting the tunnel. The setup should check that Serena is installed, download the latest stable Windows tunnel client from the official source, verify it when possible, ask for the tunnel ID and runtime API key, and store the key securely for the current Windows user instead of plain text. The start script should run a preflight check first, then launch Serena in the ChatGPT context and keep the window open while the tunnel is active.

Please include clear README instructions for Windows users, basic troubleshooting, a sample prompt for testing the connection, and a safe default config that does not hard code a project path. If you need current tunnel client details, look up the latest docs online.
