Hi, Boris.

Thanks for contributing!

As discussed internally, at the moment, we're trying to minimize the number of tools the MCP server exposes to avoid problems with smaller models or taking up too much of the token context window budget.

In this PR you're introducing multiple CRUD tools that the LLM should not need since it should be able to leverage the generic resource tools.
Similarly, for events, there is specific tooling for event retrieval that should not be necessary. In case there is a specific prompt+model combination that doesn't work with the current tooling, but works with the one proposed, we should evaluate how to deal with the specific case.

IMHO the only tool that brings something new and would be impossible to replace with current tooling is the one to retrieve the node logs. We should only keep this one.

@Cali0707 @matzew @mrunalp thoughts?

@blublinsky thanks for the PR and addressing our comments
I will test it before I merged

I tested w/ the kind-control-plane node on my machine, and changed the log-path to alternatives.log, and got results
