## Integration with AI Assistants

When Claude or other AI assistants use MCP, they can:

1. **Search Knowledge Base** for command help
2. **Get Error Explanations** when commands fail
3. **Receive Best Practices** for optimization
4. **Link to Official Docs** for deeper learning

Example Claude conversation:
```
User: "How do I find duplicate records?"
Claude: (uses MCP tool duplicateDetection)
Claude: "I found these duplicates... Here's documentation 
         on preventing duplicates in SAP HANA:"
```
