+# MarioGPT - Bug Fixes & Improvements Summary
+
+## Issues Identified and Fixed
+
+### 1. **Missing Dependencies in requirements.txt**
+**Severity:** Critical
+**Issue:** The original requirements.txt only included 4 packages (torch, transformers, scipy, tqdm) but the code required many more.
+
+**Missing packages:**
+- gradio (>=5.48.0) - Required for web interface
+- fastapi - Required for API routes
+- uvicorn[standard] - Required for running the web server
+- spaces - Required for HuggingFace Spaces GPU decorator
+- pillow - Required for image processing
+- numpy - Required for array operations
+- mcp (>=0.9.0) - For MCP server support
+- pydantic (>=2.0.0) - For data validation
+
+**Fix:** Complete requirements.txt with all necessary dependencies
+
+### 2. **Incorrect Repository URL in setup.py**
+**Severity:** Medium
+**Issue:** setup.py URL pointed to "https://github.com/kragniz/cookiecutter-pypackage-minimal" (a cookiecutter template) instead of the actual MarioGPT repository.
+
+**Fix:** Updated URL to "https://github.com/shyamsn97/mario-gpt"
+
+### 3. **No Error Handling or Logging**
+**Severity:** High
+**Issue:** Original code had no error handling, making debugging difficult and crashes ungraceful.
+
+**Improvements:**
+- Added comprehensive logging with Python's logging module
+- Added try-catch blocks around critical operations
+- Added input validation for temperature and level_size
+- Added graceful error messages for users via gr.Error()
+- Added model initialization checks
+
+### 4. **Hardcoded CUDA Device**
+**Severity:** Medium
+**Issue:** Code assumed CUDA was available with `device = torch.device('cuda')`
+
+**Fix:** Added automatic device detection:
+```python
+device = torch.device('cuda' if torch.cuda.is_available() else 'cpu')
+```
+
+### 5. **UUID Privacy Concerns**
+**Severity:** Low
+**Issue:** Used uuid.uuid1() which can expose MAC address and timestamp
+
+**Fix:** Changed to uuid.uuid4() for better randomness and privacy
+
+### 6. **Missing Directory Creation**
+**Severity:** Medium
+**Issue:** Code assumed 'static' directory exists
+
+**Fix:** Added directory creation:
+```python
+Path("static").mkdir(exist_ok=True)
+```
+
+### 7. **Incomplete setup.py Metadata**
+**Severity:** Low
+**Issue:** Missing Python version requirements, extras_require, and proper classifiers
+
+**Improvements:**
+- Added python_requires='>=3.8'
+- Added extras_require for dev, gradio, and mcp installations
+- Added proper classifiers
+- Improved package metadata
+
+### 8. **No Input Validation**
+**Severity:** Medium
+**Issue:** User inputs weren't validated before processing
+
+**Fix:** Added validation:
+```python
+temperature = max(0.1, min(2.0, float(temperature)))
+level_size = max(100, min(2799, int(level_size)))
+```
+
+### 9. **Incomplete .gitignore**
+**Severity:** Low
+**Issue:** Only ignored .DS_Store
+
+**Fix:** Created comprehensive .gitignore for Python projects including:
+- Python artifacts (__pycache__, *.pyc, etc.)
+- Virtual environments
+- IDE files (.idea, .vscode)
+- Generated files
+- Test artifacts
+- Logs
+
+## New Features Added
+
+### 1. **MCP Server Support**

+- Validates all inputs
+- Provides detailed feedback
+
+**b) get_level_suggestions**
+- No parameters
+- Returns: Curated list of example prompts
+- Organized by theme (pipes, enemies, platforms, etc.)
+
+### 2. **MCP Configuration File**

+      "command": "python",
+      "args": ["/path/to/mario-gpt/mcp_server.py"],
+      "description": "Generate Super Mario levels from text",
+      "icon": "🍄",
+      "env": {
+        "PYTHONPATH": "/path/to/mario-gpt",
+        "CUDA_VISIBLE_DEVICES": "0"
+      }
+    }
+  }
+}
+```
+
+3. **Test MCP server:**
+```bash
+# Run server manually
+python mcp_server.py
+
+# Or via MCP CLI
+mcp run mariogpt
+```
+
+### For Claude Desktop:
+
+Create/edit `~/Library/Application Support/Claude/claude_desktop_config.json`:
+```json
+{
+  "mcpServers": {
+    "mariogpt": {
+      "command": "python",
+      "args": ["/path/to/mario-gpt/mcp_server.py"]
+    }
+  }
+}
+```
+
+## Environment Variables
+
+```bash
+# Optional: Force CPU mode
+export CUDA_VISIBLE_DEVICES=""
+
+# Optional: Set custom tile directory
+export TILE_DIR="/path/to/tiles"
+
+# Optional: Set logging level
+export LOG_LEVEL="DEBUG"
+```
+
+## Testing
+
+### Test Gradio Interface:
+```bash
+python app.py
+# Visit http://localhost:7860
+```
+
+### Test MCP Server:
+```bash
+# Run server
+python mcp_server.py
+
+# In another terminal, test with MCP CLI
+echo '{"jsonrpc":"2.0","id":1,"method":"tools/list"}' | mcp run mariogpt
+```
+
+### Generate Test Level:
+```python
+import torch
+from supermariogpt.lm import MarioLM
+
+mario_lm = MarioLM()
+device = torch.device('cuda' if torch.cuda.is_available() else 'cpu')
+mario_lm = mario_lm.to(device)
+
+prompts = ["many pipes, some enemies, low elevation"]
+level = mario_lm.sample(prompts=prompts, num_steps=1399, temperature=2.0)
+print("Level generated successfully!")
+```
+
+## Troubleshooting
+
+### Issue: CUDA out of memory
+**Solution:** Reduce level_size or use CPU mode
+
+### Issue: Static files not found
+**Solution:** Ensure `static/` directory exists and has write permissions
+
+### Issue: MCP server not connecting
+**Solution:** Check Python path and verify all dependencies installed
+
+### Issue: Tiles not rendering
+**Solution:** Verify `data/tiles/` directory exists with tile images
+
+## Performance Optimization
+
+### GPU Configuration:
+```python
+# Enable TF32 for better performance on Ampere GPUs
+torch.backends.cuda.matmul.allow_tf32 = True
+torch.backends.cudnn.allow_tf32 = True
+```
+
+### Memory Management:
+```python
+# Clear cache between generations
+torch.cuda.empty_cache()
+```
