Update your Node.js version

The MCP installer requires Node.js 18 or higher. Follow the path that matches how you installed Node.

First — check what version you have

Open a terminal and run:

node --version

If it prints v18 or higher — you're good. Close this page and continue the setup.

Installed via nvm

Update with nvm (most common on Mac)

Copy and paste this into your terminal. It installs the latest LTS, sets it as default, and activates it immediately:

nvm install --lts && nvm alias default node && nvm use default

Then run node --version to confirm it now shows v18+.

Installed via Homebrew

Update with Homebrew

brew upgrade node
Fresh install

Don't have Node yet?

Download the LTS version from nodejs.org and run the installer. Then close and reopen your terminal before continuing.

After updating

Close your terminal, open a new one, and verify:

node --version

Once it shows v18 or higher, close this page and continue Step 3 of the MCP setup.
