Connect Claude Code to Railway
One line gives Claude Code your Railway account as tools: 1 endpoint, projects, more, called with your own connection. No key in the prompt, a receipt for every call, revoke Claude Code's access alone any time.
Three steps
- Create a free 0n3 account and connect Railway. Paste a key or sign in; it lands in your vault, encrypted.
- Install 0n3 into Claude Code. The terminal agent. One command, then every connection you hold is a tool in your shell. The skill file teaches it how 0n3 works.
- Ask Claude Code: whoami. Then: "List customers in Railway".
Install (user scope — every project)
claude mcp add --transport http --scope user 0n3 https://0n3.app/mcp --header "Authorization: Bearer <your 0n token>"
The line above carries a placeholder; 0n3.app/install mints a real key named for Claude Code and fills it in.
