mcpmu vs tunnel-client

mcpmu: mcpmu acts as a multiplexing gateway for the Model Context Protocol (MCP), allowing AI coding agents to access multiple MCP servers through a single, unified endpoint. It simplifies configurations, manages various server profiles, and provides granular control over tool permissions, enhancing the interoperability and security of AI agent ecosystems.; 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.
