Claude Code Setup

Claude Code is Anthropic's official coding assistant CLI. Through model-go, you can use Anthropic-compatible models directly.

Prerequisites

• You have created an API token in model-go
• You have installed Node.js 18+ Environment Check

Install

macOS / Linux

npm install -g @anthropic-ai/claude-code

Windows (run as Administrator)

npm install -g @anthropic-ai/claude-code

Verify the installation:

claude --version

Configuration

macOS / Linux (~/.claude/settings.json)

{
  "env": {
    "ANTHROPIC_BASE_URL": "https://model-go.com",
    "ANTHROPIC_AUTH_TOKEN": "your model-go token",
    "CLAUDE_CODE_ATTRIBUTION_HEADER": "0"
  }
}

Windows (%USERPROFILE%\.claude\settings.json)

{
  "env": {
    "ANTHROPIC_BASE_URL": "https://model-go.com",
    "ANTHROPIC_AUTH_TOKEN": "your model-go token",
    "CLAUDE_CODE_ATTRIBUTION_HEADER": "0"
  }
}

Creating the .claude folder on Windows

Windows File Explorer does not let you create folders that start with . directly. Use CMD instead:

mkdir "%USERPROFILE%\.claude"

Configuration Notes

Variable	Purpose
ANTHROPIC_BASE_URL	model-go API endpoint, fixed at https://model-go.com
ANTHROPIC_AUTH_TOKEN	The API token you created in model-go
CLAUDE_CODE_ATTRIBUTION_HEADER	Set to 0 to disable the attribution header

Launch

After saving the config, open a terminal in your project directory and start Claude Code:

cd your-project-folder
claude

On first launch, follow the prompts:

1. Choose a theme and press Enter
2. Confirm the security prompt and press Enter
3. Trust the working directory and press Enter
4. Start coding

Common Issues

If Claude Code still asks you to sign in or fails to connect, check the Claude Code FAQ.

WARNING

Make sure the token belongs to a group that includes Claude models. If the group does not include Claude models, requests will fail.
