tunnel-client vs agent-harness-generator

Q: Which is better, tunnel-client or agent-harness-generator?

By GitHub stars, agent-harness-generator has more community adoption, but the best choice depends on your specific use case.

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.; agent-harness-generator: MetaHarness is a unique tool that acts as a factory for AI agent frameworks, generating custom, repo-aware agent harnesses from any GitHub repository or a blank slate. It provides a branded, npm-publishable package with a CLI, scoped memory, governance policy, and integration with various agent hosts like Claude Code and OpenAI Codex, all designed to run locally without external servers.
