MCP is very much not dead. centralized remote MCP servers are incredibly useful. also bespoke CLIs still require guidance for models to use effectively, so it's clear that token efficiency is still an issue regardless.

I think cli’s are more token efficient- the help menu is loaded only when needed, and the output is trivially pipe able to grep or jq to filter out what the model actually wants

I use Playwright to intercept all requests and responses and have Claude Code navigate to a website like YouTube and click and interact with all the elements and inputs while recording all the requests and responses associated with each interaction. Then it creates a detailed strongly typed API to interact with any website using the underlying API. Yes, I know it likely breaks everybody's terms of service but at the…

Please publish!

MCPs cost nothing in CC now with Tool Search.

> MCPs cost nothing in CC now with Tool Search. This is incorrect. Plenty of people have run the numbers. Tool search does not fix all problems with MCP.

What are the numbers? Are there problems other than context usage you refer to?

Don’t know how this could be more stable than ytdlp. When issues come up they’re fixed really quickly.

yt-dlp was very recently broken for ~2 days for any Youtube videos that required cookies: https://github.com/yt-dlp/yt-dlp/issues/16212 Here is what actually fixed it: https://github.com/yt-dlp/ejs/pull/53/changes yt-dlp is relatively stable, but still occasionally breaks for long periods. I get the sense YouTube is becoming increasingly adversarial to yt-dlp as well. I don't know the details, but it doesn't seem lik…

I think having a hook to an LLM endpoint to enable yt-dlp to attempt to self resolve until an official fix is available would be a useful enhancement.

that sounds like a great tool

Why even use Playwright for this? I feel like Claude just needs agent-browser and it can generate deterministic code from it.

you mean this one? https://github.com/vercel-labs/agent-browser

As someone that does heavy agentic coding (using basically all the tools), this is so far from the truth. People claiming this have probably never worked in large enterprise environments where things like authentication, RBAC, rate limiting, abuse detection, centralized management/updates/ops, etc. are a huge part of the development and deployment workflow.

In these situations you can't just use skills and cli tools without a gigantic amount of retooling and increased operational and security complexity. MCP is really useful here, and allows centralized eng and ops teams to manage their services in a way that aligns with the organizations overall posture, policies, and infrastructure.

> Google is so far behind agentic cli coding. Gemini CLI is awful.

This part I totally agree. It's really hard to express how bad it is (and it's really disappointing.)

all you need is a simple skills.md and maybe a couple examples and codex picks up my custom toolkit and uses it.

whats your custom toolkit

It is 2 months old!

My excuse for not keeping up is that I'm in so deep that Claude Code can predict the stock market.

I'll still publish mine and see if has any value but agent browser looks very complete.

Thank you for sharing!
