Claude Code CLI

Official Anthropic terminal AI tool

1Install Claude Code CLI if you haven't: npm install -g @anthropic-ai/claude-code

2Set the environment variables in your terminal:

PowerShell

$env:ANTHROPIC_API_KEY="sk-cm-your-api-key"
$env:ANTHROPIC_BASE_URL="https://api.claudemax.pro/v1"
$env:ANTHROPIC_MODEL="claude-opus-4.6"

💡To make this permanent, add the export lines to your $PROFILE file. Or use our one-click script below.

Automatic Setup Recommended

One command configures Claude Code, MCP tools, env vars, and verifies your connection automatically.

Run one command to configure everything. You'll only need your API key.
Prerequisite: Make sure you have Node.js installed. Everything else is handled automatically.

PowerShell — One-liner setup

Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser
irm https://api.claudemax.pro/setup.ps1 | iex

Or download and run manually:

⬇ Download setup-claudemax.ps1powershell -ExecutionPolicy Bypass -File setup-claudemax.ps1

What the script does:

✓Validates your API key

✓Sets permanent environment variables

✓Configures Claude Code (~/.claude/settings.json)

✓Installs ClaudeMax MCP tools (web_search, understand_image)

✓Configures MCP server (~/.claude.json)

✓Installs Claude Code CLI

💡Re-run anytime to update your API key or reconfigure. The script is idempotent — it safely merges settings without losing your other configuration.

Manual MCP Configuration

If you prefer to configure manually instead of using the automatic script

1Install ClaudeMax MCP tools:

Terminal

npm install -g claudemax-mcp

2Configure environment — Create or edit %USERPROFILE%\.claude\settings.json:

%USERPROFILE%\.claude\settings.json

{
  "env": {
    "ANTHROPIC_AUTH_TOKEN": "sk-cm-your-api-key",
    "ANTHROPIC_BASE_URL": "https://api.claudemax.pro/v1",
    "ANTHROPIC_MODEL": "claude-opus-4.6",
    "ANTHROPIC_SMALL_FAST_MODEL": "claude-haiku-4.5",
    "ANTHROPIC_DEFAULT_SONNET_MODEL": "claude-sonnet-4.6",
    "ANTHROPIC_DEFAULT_OPUS_MODEL": "claude-opus-4.6",
    "ANTHROPIC_DEFAULT_HAIKU_MODEL": "claude-haiku-4.5",
    "CLAUDE_CODE_DISABLE_NONESSENTIAL_TRAFFIC": "1"
  },
  "hasCompletedOnboarding": true
}

3Configure MCP server — Create or edit %USERPROFILE%\.claude.json:

%USERPROFILE%\.claude.json

{
  "mcpServers": {
    "ClaudeMax": {
      "command": "npx",
      "args": ["-y", "claudemax-mcp"],
      "env": {
        "CLAUDEMAX_API_KEY": "sk-cm-your-api-key",
        "CLAUDEMAX_URL": "https://api.claudemax.pro"
      }
    }
  }
}

4Restart Claude Code or VS Code to apply the new settings.

💡Replace sk-cm-your-api-key with your actual API key in both files. The MCP server will automatically start when Claude Code launches.
