Tools: Code Is All You Need

I think the Playwright MCP is a really good example of the overall problem that the author brings up.

However, I couldn’t really understand if he’s saying that the Playwright MCP is good to use for your own app or whether he means for your own app just tell the LLM directly to export Playwright code.

it's the latter: "you can actually start telling it to write a Playwright Python script instead and run that".

and while running the code might faster, it's unclear whether that approach scales well. Sending an MCP tool command to click the button that says "X", is something a small local LLM can do. Writing complex code after parsing significant amount of HTML (for correct selectors for example) probably needs a managed model.
