What are your other primitives for orchestration?

> The part about tool count increasing coordination overhead is interesting too. I've been considering exposing just a single tool to address this, but I wonder how this plays out as people start stacking more MCP servers together.

It works really well. Whatever knowledge LLMs absorb about CLI commands seems to transfer to MCP use so a single tool with commands/subcommands works very well. It’s the pattern I default to when I’m forced to use an MCP server instead of providing a CLI tool (like when the MCP server needs to be in-memory with the host process).
