  3. Run: nano ~/setup-claude-mac.sh

  4. Paste in the following script (which is also available on https://utexas.sharepoint.com/sites/AIStudio/SitePages/Getting-Started-with-Claude-Code.aspx?CT=1776970062846&OR=OWA-NT-Mail&CID=b7f143d3-d777-e9d0-87f3-fd195be59bb9):

 

#!/bin/bash

# setup-claude-mac.sh

 

CLAUDE_PATH=$(which claude 2>/dev/null)

if [ -z "$CLAUDE_PATH" ]; then

    echo "Error: Claude Code not found in PATH"

    echo ""

    echo "Please install Claude Code first:"

    echo "  curl -fsSL https://claude.ai/install.sh | bash"

    echo ""

    echo "Then close and reopen your terminal, and run this script again."

    exit 1

fi

 

echo "Found Claude Code at: $CLAUDE_PATH"

echo ""

 

if [ -f ~/.claude/settings.json ]; then

    BACKUP_FILE=~/.claude/settings.json.backup.$(date +%Y%m%d_%H%M%S)

    cp ~/.claude/settings.json "$BACKUP_FILE"

    echo "Backed up existing settings to: $BACKUP_FILE"

    echo ""

fi

 

mkdir -p ~/.claude

echo "Verified ~/.claude directory exists"

echo ""

 

echo "━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━"

echo "Configuration Setup"

echo "━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━"

echo ""

 

read -s -p "Enter your Portkey API key: " API_KEY

echo ""

if [ -z "$API_KEY" ]; then

    echo "Error: API key cannot be empty"

    exit 1

fi

 

read -p "Enter your integration slug (found in Model Catalog): " SLUG

echo ""

if [ -z "$SLUG" ]; then

    echo "Error: Slug cannot be empty"

    exit 1

fi

 

read -p "Enter the model that is enabled for your API key (e.g., haiku): " MODEL_INPUT

echo ""

if [ -z "$MODEL_INPUT" ]; then

    echo "Error: Model cannot be empty"

    exit 1

fi

 

cat > ~/.claude/settings.json << EOF

{

  "env": {

    "ANTHROPIC_BASE_URL": "https://api.portkey.ai",

    "ANTHROPIC_AUTH_TOKEN": "dummy",

    "ANTHROPIC_CUSTOM_HEADERS": "x-portkey-api-key: ${API_KEY}\\nx-portkey-provider: @${SLUG}"

  },

  "model": "${MODEL_INPUT}"

}

EOF

 

echo "Configuration saved to ~/.claude/settings.json"

 

cat << EOF > ~/.claude.json

{

  "hasCompletedOnboarding": true

}

EOF

 

echo "Created ~/.claude.json with onboarding settings"

echo ""

echo "Your Claude Code installation is now configured to use:"

echo "Portkey API at: https://api.portkey.ai"

echo ""

echo "You can now use 'claude' command normally."

echo ""

 

  1. Save this script by pressing Ctrl + O (letter O not zero), and then press Enter

  2. Exit by pressing Ctrl + X

  3. Run: ls -l ~/setup-claude-mac.sh

  4. Run: chmod +x ~/setup-claude-mac.sh

  5. Run: ~/setup-claude-mac.sh 

  6. Enter your Portkey API key, which can be found on PortKey under “API Keys” (Read here about how to get your UT Austin API Key: https://utexas.sharepoint.com/sites/AIStudio/SitePages/Getting-Started-with-Claude-Code.aspx?CT=1776970062846&OR=OWA-NT-Mail&CID=b7f143d3-d777-e9d0-87f3-fd195be59bb9#getting-your-ut-austin-api-key)

  1. Enter your integration slug (found in Model Catalog) [I entered csdi-madrlab-anthropic]

 

  1. Enter the model that is enabled for your API key (e.g., haiku) [I entered haiku]

Then it should be set up and you will be able to use Claude code by typing “claude” and hit enter in your terminal.
