• src/pydantic_mcp/tools.py:223-235 (handler)

  The handler function `compare_validation_modes` which executes the tool by resolving the target and building a validation comparison.

  def compare_validation_modes(
      target: str,
      data: object,
  ) -> ToolResponse:
      """Compare model, TypeAdapter, strict, and JSON-vs-Python validation behavior."""
      runtime_target = resolve_target(
          target,
          registry=REGISTRY,
          settings=SERVER_SETTINGS,
      )
      response = build_validation_comparison(runtime_target, data=data)
      _record_response_errors("compare_validation_modes", target, response)
      return response
