Chrome DevTools MCPがVSCodeで起動しない原因と解決法

Last updated at Posted at 2025-11-05

症状

VSCodeでchrome-devtools-mcpを使おうとしたところ、以下のエラーが発生:

ERROR: chrome-devtools-mcp does not support Node v20.11.0. Please upgrade to Node 20.19.0 LTS or a newer LTS.

wsl上で

$ node -v 
しても
$ v20.19.0 
と出る。謎だ・・・

原因

Windowsの方のnodeのバージョンがv20.11.0になっていました。

解決

WindowsのnodeをアップデートしたらMCPサーバーが起動!
VSCodeのMCPサーバーはWindowsの方で動くんすね。知らずに時間を浪費してしまった・・・

一応コマンド↓

nvm install 20.19.0
nvm use 20.19.0

この記事で解決できたら幸いです。
