Before installing an AI CLI, make sure you’ve completed Yellow.pro’s account setup first — connecting your wallet, creating a sub-account, and completing verification. See Agent Onboarding for the full walkthrough. The steps below assume your Yellow.pro account is already set up and you’re ready to pair an AI agent to it.
Claude Code and Claude Desktop are two separate applications from Anthropic. Claude Desktop is the chat app (Chat/Cowork tabs); Claude Code is a command-line tool that runs in a terminal. The Yellow.pro MCP server registers with Claude Code specifically — if you only have Claude Desktop installed, the steps on the Installation page will not find anywhere to register.
If claude --version already works in your terminal, skip ahead to Installation. Otherwise, follow the steps below first.
1

Install

Run the native installer for your platform:
This downloads the claude binary directly — no separate Node.js or npm setup needed for this step.
2

Verify

Open a new terminal window (a window that was already open won’t see the updated PATH), then run:
A working install prints something like 2.1.263 (Claude Code).
If you see command not found: claude, the installer likely finished without adding itself to your PATH. Fix it with:
(Use ~/.bash_profile instead of ~/.zshrc if your shell is bash, not zsh.) Then open a fresh terminal window and re-run claude --version.
If you see claude native binary not installed, the platform-specific binary failed to download. Re-run the installer above (not npm install) — this resolves it in almost all cases.

Log in

Run:
This opens an interactive session and prompts you to sign in through your browser on first run. If you land on pay-per-use API billing instead of your subscription plan, run /login inside the session to switch.
Claude Code requires a Pro, Max, Team, Enterprise, or Console account — the free Claude.ai plan does not include Claude Code access.
Once logged in, exit back to your normal shell prompt (type exit or press Ctrl+C) before continuing to Installation — the Yellow.pro setup commands are regular shell commands, not something you run inside an active Claude Code session.

Troubleshooting

Terminal appears frozen after pasting a multi-line command. This usually means a quote character was altered in transit (e.g. a straight ' became a curly '), and the shell is silently waiting for you to close it — check whether your prompt reads dquote> or quote> instead of the normal prompt. Press Ctrl+C to cancel, then re-enter the commands one line at a time instead of pasting a multi-line block.
Next: continue to Installation to install and register the Yellow.pro MCP server with Claude Code.
