My use cases are almost all 3rd party integrations.
Have you seen any improvements converting on MCPs that require persistency into CLI?
One important aspect of mcpshim which you might want to bring into clihub is the history idea. Imagine if the model wants to know what it did couple of days ago. It will be nice to have an answer for that if you record the tool calls in a file and then allow the agent to query the file.
