Chatgpt Web MCP Tunnel · cnproduct bundle Safely set up, diagnose, and verify OpenAI Secure MCP Tunnel connections from ChatGPT or another supported OpenAI surface to a private or local MCP server.

Do not use for ordinary public MCP endpoints, subscription-quota workarounds, or unsupported claims about model access or billing.
