Install Node.js
Atlas MCP runs on Node.js. Most machines don't have it installed by default. This takes about 2 minutes.
Check if you already have it
Open Terminal (Mac) or Command Prompt (Windows) and run:
node --version
If you see a version number like v20.11.0 or higher, you're good. Skip to Connect Claude.
If you see "command not found" or an error, follow the steps below.
