Yep. Most MCP servers are best repackaged as a cli tool, and telling the LLM to invoke `toolname --help` to learn how to use it at runtime. The primary downside is that they LLM will have a lower proclivity to invoke those tools unless explicitly reminded to.

If you do like rolling your own MCP servers, I've had great success recently refactoring a bunch of my own to consume fewer tokens by, instead of creating many different tools, consolidating the tools and passing through different arguments.
