inspectr vs tunnel-client
inspectr: Inspectr is a lightweight and high-performance API Proxy designed for reviewing, analyzing, and debugging API requests, MCP tool calls, and webhook events. It also offers a built-in tunnel option for securely sharing local services publicly, streamlining integration testing, monitoring, and troubleshooting payload issues.; 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.

TL;DR
Choose inspectr if…Debugging During Development: Real-time monitoring and inspection of requests to identify malformed data or errors.
Choose tunnel-client if…Connecting a private or localhost MCP server to OpenAI-hosted products like ChatGPT when public internet access is restricted.
