tunnel-client

`tunnel-client` is an agent designed to establish a secure connection between private or localhost MCP (Model Context Protocol) servers and OpenAI's product offerings, such as ChatGPT and Codex, via an OpenAI-hosted MCP tunnel endpoint, ensuring the MCP server remains inaccessible from the public internet. Key features include embedded health checks, readiness protocols, and metrics endpoints, as well as compatibility with various deployment environments like Docker and Kubernetes.
