mcp_kit.factory

Factory for creating instances from configuration using reflection. This module provides a central registry to avoid circular imports and supports both Target and ResponseGenerator creation.

create_object_from_config​

def create_object_from_config(config: DictConfig,
                              get_class_name: Callable[[str], str],
                              get_module_name: Callable[[str], str],
                              object_type_name: str = "object") -> Any

Generic factory function to create any object instance from configuration using reflection.

Arguments:

  • config: Configuration from OmegaConf with a 'type' field
  • get_class_name: Function that converts type string to class name
  • get_module_name: Function that converts type string to module name
  • object_type_name: Name of object type for error messages (e.g., "target", "generator")

Raises:

  • ValueError: If type is unknown or cannot be instantiated

Returns:

Object instance

create_target_from_config​

def create_target_from_config(config: DictConfig) -> Target

Factory function to create any Target instance from configuration using reflection.

Arguments:

  • ValueError: If target type is unknown or cannot be instantiated

Returns:

Target instance

create_response_generator_from_config​

def create_response_generator_from_config(
        config: DictConfig) -> ResponseGenerator

Factory function to create any ResponseGenerator instance from configuration using reflection.

Arguments:

  • config: ResponseGenerator configuration from OmegaConf

Raises:

  • ValueError: If generator type is unknown or cannot be instantiated

Returns:

ResponseGenerator instance

create_tools_from_config​

def create_tools_from_config(config: DictConfig) -> list[Tool] | None

Factory function to create any Tool instance from configuration using reflection.

Arguments:

  • config: Tool configuration from OmegaConf

Returns:

List of Tool instances or None if no tools are defined
