This is awesome, thank you. What's missing now is an MCP for Wireshark.

Thanks! Actually, there is already an MCP for Wireshark, for example https://github.com/0xKoda/WireMCP

This is awesome. Your comparison make it easy. This approach makes perfect sense to give 100% visibility into the back and forth.

Is it possible to add a simple browser page to brows the data in a simple way?. Thank you.

Its really a great tool. The gap of visualization of calling the AI client is covered by your product!!

Thank you! Showing the data in a web page should definitely be possible. But I’m not sure if this matches the original idea I had, where the tool would run in the terminal only. Why do you feel the need to show the data in a web page? Is there anything missing in the CLI?

To be fair, it is really simple to build your own proxy. I built a custom authentication layer with logging and limits for Dify MCP with just 2 prompts in Kimi. Later built it out with database limts etc.
