Yes. It works well if you can keep it connected. there are issues with authentication. You need to authenticate with the cli first, then reconnect the mcp server. It drops authentications and fails from time to time too. They need to add authentication to the mcp setup.

I do it via vscode, not directly through claude's CLI and it works fine

What are ya'll doing to get this to work? It never can connect no matter how I try it.

I have been trying to deploy an MCP server to Railway from GitHub for hours and I am almost at the point of shooting myself. The CLI is abominable. The docs are abominable. I am almost ready to go give Render or Replit my hard earned money, or AWS my sanity.

It seems that railway authenticates to the terminal session so that whenever you auth in a terminal window it auths...but then your claude is in vscode or something and it loses authentication. I've only gotten claude to work with it if I open terminal, then railway login, then claude will work with it because they are the same terminal session. Railway needs to fix this on their end I think.

Do you mean using the mcp or is claude using the railway vscode extension or IDE extension somehow? I haven't had any success with claude code using railway mcp on VScode really.
