Customer-run client for Secure MCP Tunnel: connect private or localhost MCP servers to ChatGPT, Codex, the Responses API, and AgentKit without exposing them to the public internet.
openai/tunnel-client is a customer-run program that connects a private or local MCP server to ChatGPT, Codex, the Responses API, or AgentKit through an OpenAI-hosted tunnel. It is for operators who need these OpenAI products to reach an MCP server without exposing that server to the public internet.
