   npm install -g @ironclads/namecheap-mcp@1.4.4
   
   # Check installation
   which namecheap-mcp
   ```

2. **API Authentication Errors**
   - Verify your API credentials at [Namecheap API Settings](https://ap.www.namecheap.com/settings/tools/apiaccess/)
   - Ensure your IP address is whitelisted
   - Check that API access is enabled for your account

3. **MCP Connection Issues**
   - Verify Claude Desktop configuration file location
   - Check JSON syntax in configuration file
   - Try `/mcp reload` in Claude Desktop
   - Check environment variables are set correctly

4. **Sandbox vs Production**
   - Use `NAMECHEAP_SANDBOX=true` for testing
   - Set `NAMECHEAP_SANDBOX=false` for production operations
   - Sandbox and production have separate API endpoints
