registry vs tunnel-client

registry: The BioContextAI Registry maintains a curated list of Model Context Protocol (MCP) servers, enhancing their discoverability for biomedical research and clinical activities. It provides guidelines and a submission process for developers to add their compliant, open-source MCP servers to the official registry.; tunnel-client: `tunnel-client` is a customer-run agent that securely connects private or localhost Model Context Protocol (MCP) servers to OpenAI products like ChatGPT and Codex through an OpenAI-hosted tunnel. It enables secure access for AI models without exposing the MCP server to the public internet, simplifying deployments in restricted network environments.
