import {
    extractAndParseToolsToJson,
    extractAndParseToolsXmlToJson,
    extractAndParseToolsTextToJson,
} from 'mcp-bone';

const tools = extractAndParseToolsTextToJson(text);
const tools = extractAndParseToolsXmlToJson(text);
const tools = extractAndParseToolsToJson(text);

These tools are used after LLM completions whic does not support function calling to parse the text into tools JSON. If the result is an empty array, it means that the LLM did not generate any tools.
