mcp_kit.targets.mocked

Mocked target implementation that generates fake responses.

MockConfig

@dataclass
class MockConfig()

Configuration for mocked target behavior.

Arguments:

• tool_response_generator: The generator to use for creating mock responses
• prompt_engine: The engine to use for creating mock prompt responses

MockedTarget

class MockedTarget(Target)

Target that wraps another target and generates mock responses.

This target implementation intercepts tool calls and generates synthetic responses instead of calling the actual target. Useful for testing and development scenarios.

__init__

def __init__(target: Target, mock_config: MockConfig) -> None

Initialize the mocked target.

Arguments:

• target: The base target to wrap
• mock_config: Configuration for mock behavior

name

@property
def name() -> str

Get the target name with '_mocked' suffix.

Returns:

The target name with mocked indicator

from_config

@classmethod
def from_config(cls, config: DictConfig) -> Self

Create MockedTarget from configuration.

Arguments:

• config: Target configuration from OmegaConf

Returns:

MockedTarget instance

initialize

async def initialize() -> None

Initialize the base target.

list_tools

async def list_tools() -> list[Tool]

List tools from the base target.

Returns:

List of available tools from the base target

call_tool

async def call_tool(name: str,
                    arguments: dict[str, Any] | None = None) -> list[Content]

Generate a mock response for the specified tool.

If a tool_response_generator is configured, generates a synthetic response. Otherwise, delegates to the base target.

Arguments:

• name: Name of the tool to mock
• arguments: Arguments that would be passed to the tool

Raises:

• ValueError: If the specified tool is not found
• LlmAuthenticationError: If LLM authentication fails (exits program)

Returns:

Generated mock content response or response from base target

close

async def close() -> None

Close the base target.

list_prompts

async def list_prompts() -> list[Prompt]

List prompts from the base target.

Returns:

List of available prompts from the base target

get_prompt

async def get_prompt(name: str,
                     arguments: dict[str, str] | None = None
                     ) -> GetPromptResult

Generate a mock response for the specified prompt.

If a prompt_engine is configured, generates a synthetic response. Otherwise, delegates to the base target.

Arguments:

• name: Name of the prompt to get
• arguments: Arguments to pass to the prompt

Returns:

Prompt result (generated or from base target)
