Yeah, there's a ton of great improvements in 7-28. I'm personally excited about what you posted about, but also with [tasks](https://blog.modelcontextprotocol.io/posts/2026-07-28-releas...) being officially adopted.

> I couldn’t find a great CLI tool for interactively probing an MCP server

What about mcp-inspector? It’s a nice tool, can be used interactively, can be used as a CLI.

I'm glad MCP is getting simpler

a few months ago I tried to implement an MCP server from scratch in python (instead of using the existing reference implementation) and I could not get it to work reliably across clients

Maybe someone could set up a CLI tool for agents such that you can give them a shell but they use this CLI tool instead of raw curl.

Like a tool where the AI can only call out to certain APIs based on a config file the agent cannot change.

That way you can leverage all the shell knowledge agents already have while still limiting what network calls they can make, and you wouldn't have to set up a server to use an agent.
