• src/pydantic_mcp/tools.py:129-150 (handler)

  The core implementation of the `validate_data` tool, which handles the validation logic by resolving the target and calling `validate_with_adapter`.

  def validate_data(
      target: str,
      data: object,
      mode: str = "python",
      strict: bool = False,
      context: dict[str, object] | None = None,
  ) -> ToolResponse:
      """Validate input against a model name or Python type expression."""
      runtime_target = resolve_target(
          target,
          registry=REGISTRY,
          settings=SERVER_SETTINGS,
      )
      response = validate_with_adapter(
          runtime_target,
          data=data,
          mode=mode,
          strict=strict,
          context=context,
      )
      _record_response_errors("validate_data", target, response)
      return response
