Domain Migration Guide

Phoenix is migrating to a new domain: phoenix.hginsights.com

What's Changing​

  • Old Domain: phoenix-af.vercel.app
  • New Domain: phoenix.hginsights.com
  • Transition Period: 1 month (both domains will work)
  • Deprecation Date: [DATE + 1 month]

Action Required​

If You Use MCP (Claude Desktop, Cline, etc.)​

Update your MCP configuration file:

Before:

{
  "mcpServers": {
    "phoenix": {
      "url": "https://phoenix-af.vercel.app/api/ai/YOUR_API_KEY/mcp"
    }
  }
}

After:

{
  "mcpServers": {
    "phoenix": {
      "url": "https://phoenix.hginsights.com/api/ai/YOUR_API_KEY/mcp"
    }
  }
}

Locations:

  • Claude Desktop (macOS): ~/Library/Application Support/Claude/claude_desktop_config.json
  • Claude Desktop (Windows): %APPDATA%\Claude\claude_desktop_config.json
  • Cline (VS Code): Settings → Cline MCP → Edit settings.json

If You Use Direct API Calls​

Update your base URL:

  • Old: https://phoenix-af.vercel.app/api/...
  • New: https://phoenix.hginsights.com/api/...

If You Use OAuth (Google/Microsoft Login)​

✅ No action required - OAuth redirects work with both domains during transition.

Timeline​

DateEvent

Verification​

After updating your configuration:

  1. Test MCP Connection: Ask your AI assistant: "What Phoenix tools are available?"

  2. Test API Access: Make a request to: https://phoenix.hginsights.com/api/health

  3. Check OAuth: Sign out and sign back in to verify authentication works

Troubleshooting​

MCP Connection Fails​

  • Verify you updated the URL in the correct config file
  • Restart your MCP client (Claude Desktop, VS Code, etc.)
  • Check that your API key is still valid

API Authentication Errors​

  • Regenerate your API key in Phoenix settings
  • Update your configuration with the new key

Old Domain Still Works​

✅ This is expected during the 1-month transition period
