# MCP Tools Refactoring Checklist

## All 9 Tools Successfully Refactored

### Refactoring Pattern Reference
All tools now follow the pattern established by `search_properties`:

```python
@app.tool()
async def tool_name(
    param1: type1,
    param2: Optional[type2] = None,
    ...
) -> Dict[str, Any]:
    """Tool description.

    Args:
        param1: Description
        param2: Description
        ...
    """
    # Function implementation with individual parameters
    # No request.field references
```

## Quality Assurance

### Code Verification
- [x] Python syntax check passed
- [x] No remaining Pydantic request models in @app.tool() signatures
- [x] All function bodies properly updated for individual parameters
- [x] All docstrings include Args sections
- [x] Default values match original model definitions

### Type Consistency
- [x] Required vs optional parameters correctly specified
- [x] Default values match Pydantic model Field defaults
- [x] Return types unchanged
- [x] No breaking changes to function behavior

### Documentation
- [x] Refactoring summary created: `/home/rpm/claude/mcrentcast/REFACTORING_SUMMARY.md`
- [x] Comprehensive before/after comparisons documented
- [x] Benefits section explains the refactoring rationale
- [x] All changes are traceable and reversible

## Next Steps (Optional)

### Consider For Future Work
1. **Remove Unused Pydantic Models** - The following request model classes can be removed from lines 58-123 if no longer needed:
   - SetApiKeyRequest
   - PropertyByIdRequest
   - ValueEstimateRequest
   - RentEstimateRequest
   - ListingSearchRequest
   - ListingByIdRequest (never used)
   - MarketStatsRequest
   - ExpireCacheRequest
   - SetLimitsRequest

2. **Update Documentation** - Update any external API documentation or client libraries that reference these request models

3. **Version Release** - Tag this as a new version (using date-based versioning: YYYY-MM-DD) to reflect the API changes

## Status: COMPLETE

All 9 MCP tools have been successfully refactored to use individual parameters instead of Pydantic model classes. The refactoring improves FastMCP protocol compatibility, code clarity, and maintainability.
