Ryan Malloy 12dc79f236 Refactor all MCP tool definitions to use individual parameters 
Replace Pydantic model classes with individual function parameters across all 9 tools:
- set_api_key: SetApiKeyRequest -> api_key parameter
- get_property: PropertyByIdRequest -> property_id, force_refresh parameters
- get_value_estimate: ValueEstimateRequest -> address, force_refresh parameters
- get_rent_estimate: RentEstimateRequest -> 6 individual parameters
- search_sale_listings: ListingSearchRequest -> 7 individual parameters
- search_rental_listings: ListingSearchRequest -> 7 individual parameters
- get_market_statistics: MarketStatsRequest -> 4 individual parameters
- expire_cache: ExpireCacheRequest -> 3 individual parameters
- set_api_limits: SetLimitsRequest -> 3 individual parameters

This improves FastMCP protocol compatibility and simplifies parameter handling.
All function logic remains unchanged, with comprehensive docstrings added.

# 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.
