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:

@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

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

Type Consistency

  • Required vs optional parameters correctly specified
  • Default values match Pydantic model Field defaults
  • Return types unchanged
  • No breaking changes to function behavior

Documentation

  • Refactoring summary created: /home/rpm/claude/mcrentcast/REFACTORING_SUMMARY.md
  • Comprehensive before/after comparisons documented
  • Benefits section explains the refactoring rationale
  • 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.
