MCPs are diminishing in value a bit, because AI Agents are getting smarter about using API/CLIs. For example, I use gh cli via Claude instead of their MCP, because I already had cli setup, so no need to use MCP. MCPs can potentially have great value if they cross multiple sources and combine results. For example at work we use an in-house MCP for log/metrics search across five different (legacy) systems. It finds cor…

Agree with this.

MCP and RAG feel like the usual pattern of running a daemon 24/7 that balloons infrastructure spend. So uncivilized.

Any given REST API is a small model. A frontier or local model and modern harness can parse the already existing documentation for that REST API and invoke or generate a tool to use it.

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.

Earlier quoted context omitted.

Can I hear more? I suspect you’re being downvoted because 500m a day (for that many days) is a bit much, but there’s definitely plausibility, here. If we all can’t hear more here, can I hear more by being your Executive Assistant?

I'm addicted. This is the most fun I've had coding in decades. I feel like I've got superpowers and the limit is just how quickly I can prompt out my ideas. Those 500m are for coding. Started with $20 and now I'm on the $200/mo codex plan. Resets are crazy... free tokens, why not take advantage of all that VC money? Using omp helps a lot too, the fact that it uses an LSP under the covers is a game changer. I'm buildi…

Second-to-last paragraph has me non-jokingly interested in talking about working on something together.

Interested in chatting about a bigger swing, following the same user-first design mentality?

I have a great niche staked out, have operated in it previously for somebody else, personally elicited most if not all of the pain points of the underserved users in mind.

I saw ridecontrol a day or so ago - very sleek UX, and sharp UI; I sent it to all relevant contacts!
