THEN Install the MIT-licensed @apifold/transformer package. Use 'autoConvert' to handle Swagger 2.0→OpenAPI 3.x migration, then 'parseSpec' followed by 'transformSpec' to get an array of MCPToolDefinition objects that can be used with any MCP server runtime.

import { parseSpec, transformSpec, autoConvert } from '@apifold/transformer';
const { spec } = await autoConvert(rawSpec);
const parsed = parseSpec({ spec });
const { tools } = transformSpec({ spec: parsed.spec });
