Your Question

Admittedly, long-time trier and lurcher. Yet, new-ish to code. But let's be honest—this is pretty straightforward.

So why am I hours into just these three, with both Git setups being the worst? The Git server—I’m not even sure how I got it working. Now the GitHub one? It connects, then disconnects.

I’ve created so many PATs, from full auth to minimal, both classic and fine-grained. I logged the env locally, ran it, and ran it through the terminal. Everything started fine. I close out Claude (a million times), and it just connects, then disconnects.

I can’t reason this out anymore. What am I missing?

Please and thanks,
Jason

Again not a coder, so bare with me.

To get it to work though, I uninstalled npm. Installed nvm, then installed and use node 22. It works now.

Anyone can explain why, that would be cool!

I can maybe help as I just set this up. By installing nvm it would of linked npx globally into your env, just run which npx from your terminal to verify. When Claude Desktop Agent boots it can then use the same cli command to start the MCP agent server. Why it felt like it magically just fixed itself. The great thing about this approach is that the other nodejs/npm packages will work the same such as the file-system mcp server.
