@daoluc Thanks for sharing your system info.
Could you try upgrading your Node.js installation to a newer version? We recommend an Active LTS release (Node.js v22). Node.js v18 reached End-of-life (EoL) earlier this year, so it's not something we aim to support currently. https://nodejs.org/en/about/previous-releases
I've tested that the latest MCP server runs successfully with Node.js v22.18.0—let us know if upgrading resolves the issue on your end too!
@mattrossman, thank you for your quick reply! Just added the absolute PATH to the MCP config. Seems to use active LTS now but still same issue.

@renierbleeker83 Maybe try uninstalling Node v18 so it's no longer present in paths? Also, could you share more details on your setup (what OS, what MCP client?) I see "claude-ai" listed as the client, not sure if that means Claude Code or Desktop.
Personally I use mise for Node version management and Cursor as an MCP client.
