Function: response()

function response(data): ResponseBuilder;

Defined in: packages/core/src/presenter/ResponseBuilder.ts:389

Create a new response builder for composing multi-block MCP responses.

This is the recommended standalone function for building rich responses with UI blocks, LLM hints, and system rules. It keeps the handler's ctx pure — no framework methods injected.

For simple responses, continue using success and error. Use response() when you need JIT context, UI blocks, or domain rules.

Parameters

Parameter	Type	Description
data	string | object	A string message or any JSON-serializable object

Returns

ResponseBuilder

A new ResponseBuilder for chaining

Example

import { response, ui } from '@vinkius-core/mcp-fusion';

// Simple (equivalent to success())
return response('Task created').build();

// Rich multi-block response
return response(sprintData)
    .uiBlock(ui.echarts(burndownConfig))
    .llmHint('Summarize the sprint progress analytically.')
    .systemRules(['Use tables for task lists.'])
    .build();
