## Common Use Cases

### Use Case 1: Scene Creation from Claude Desktop
**Documentation:** UMCP_QUICK_REFERENCE.md → Workflow 1
**Steps:**
1. Spawn actors with positions
2. Apply transformations
3. Organize with level-organizer skill
4. Capture screenshot for validation

---

### Use Case 2: Asset Discovery and Management
**Documentation:** UMCP_ANALYSIS_SUMMARY.md → Asset Management
**Steps:**
1. List assets in /Game folder
2. Query specific asset info
3. Create materials or import new assets
4. Save changes

---

### Use Case 3: Python-Driven Automation
**Documentation:** UMCP_QUICK_REFERENCE.md → Python Execution
**Steps:**
1. Write Python code using Unreal API
2. Execute via execute_python command
3. Batch operations for efficiency
4. Error handling and logging

---

### Use Case 4: Blueprint Automation
**Documentation:** UMCP_ANALYSIS_SUMMARY.md → Blueprint Operations
**Steps:**
1. Create blueprint via tool
2. Add components
3. Use auto_wire_blueprint for connections
4. Compile and test

---

## Architecture Highlights

### Multi-Instance Support
- Automatic port allocation
- Instance discovery mechanism
- Token-based authentication per instance
- Current instance: kariana-11025-1764507256524-29acaf30

### Progressive Disclosure
- Core tools for atomic operations
- Skills for complex workflows
- Lazy loading of advanced features
- Modular architecture (46 handlers, 29 exposed)

### Thread Safety
- Thread-safe commands: ping, list_*, get_server_info
- Main-thread commands: All Unreal API calls
- Queue-based execution for thread safety
- 15-second timeout for main thread operations

---

## Integration Patterns

### Pattern 1: Direct Socket Communication
```python
import socket, json

sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sock.connect(('localhost', 9877))
request = {'type': 'spawn_actor', 'pin': '4336', 'actor_class': 'Cube', 'name': 'Test'}
sock.sendall(json.dumps(request).encode() + b'\n')
response = sock.recv(4096)
```

### Pattern 2: Claude Desktop MCP
```
User: "Create 10 cubes in a circle pattern"

Claude uses:
1. execute_python with math for circle calculations
2. Multiple spawn_actor calls
3. set_actor_location for positioning
4. execute_skill('level-organizer') for cleanup
```

### Pattern 3: Python-Driven Batch Operations
```python
code = """
import unreal
for i in range(10):
    location = [i*100, 0, 0]
    actor = unreal.EditorLevelLibrary.spawn_actor_from_class(
        unreal.Cube.static_class(), location
    )
"""

umcp_command('execute_python', code=code)
```

## Troubleshooting Guide

### Issue: Connection Refused
**Symptoms:** Cannot connect to localhost:9877
**Solutions:**
1. Verify Unreal Engine is running
2. Check KarianaUMCP plugin is enabled
3. Look for "KarianaUMCP: Listening on port 9877" in UE log
4. Restart socket server via Python: `unreal.PythonScriptPlugin.execute_script(...)`

### Issue: Authentication Failed
**Symptoms:** "Authentication required" error
**Solutions:**
1. Include PIN in request: `{"pin": "4336", ...}`
2. Get current PIN: `{"type": "get_pin"}`
3. Check Unreal log for PIN display

### Issue: Actor Not Found
**Symptoms:** "Actor not found" or similar
**Solutions:**
1. List actors first: `{"type": "list_actors"}`
2. Use exact name (case-sensitive)
3. Verify actor exists in World Outliner
4. Use full path if needed: `/Game/Level.Level:PersistentLevel.ActorName`

### Issue: Command Timeout
**Symptoms:** No response after 15 seconds
**Solutions:**
1. Check Unreal is not frozen
2. Simplify operation (break into smaller commands)
3. Use Python execution for long operations
4. Check Unreal log for Python errors

---

## Performance Considerations

### Response Times
- **Fast (<100ms):** ping, list_functions, list_actors
- **Medium (100-500ms):** spawn_actor, set_actor_*, list_assets
- **Slow (500ms+):** execute_python (depends on code), skills, screenshots

### Best Practices
1. **Batch operations via Python** instead of multiple tool calls
2. **Use skills for workflows** rather than manual orchestration
3. **Cache actor lists** instead of querying repeatedly
4. **Test with ping** before complex operations

### Limits
- **Max timeout:** 15 seconds for main thread operations
- **Concurrent requests:** Single-threaded, queued execution
- **Screenshot size:** Default 800x600 (configurable)

---

## Security Notes

### Current Configuration
- Authentication: PIN-based (4336)
- Public exposure: ngrok tunnel active
- Token system: Available but not required

### Recommendations
1. Rotate PIN when using ngrok
2. Enable token auth for production
3. Restrict network access in sensitive environments
4. Audit Python execution requests
5. Monitor for unusual activity
