I am a single person LLC so my "production" is just me using AI to build things. I use MCP for some things, like Playwright; for web UI development, but I also use CLIs, especially custom CLIs I create that have built-in help for the AI coding agent to use. I just to run my command (in the path) with --help and it figures out how to use. This seems more straightforward and efficient than MCP. I have written MCP servers for all sorts of things, like monitoring remote systems, operating a PvP game as PvAI, others but lately I just create a new CLI with help. I use this with Claude, Codex, Gemini, and opencode (z.ai GLM) instead of dealing with how each agent registers MCPs.
