JavaScript SDK

Install the JavaScript client:

npm install @dust-tt/client

Point the client at Counso and provide the workspace ID and an API key or OAuth access token:

import { DustAPI } from "@dust-tt/client";

const client = new DustAPI(
  { baseUrl: "https://app.counso.ai", workspaceId, apiKey }
);

Keep credentials in your application’s secret store or a secure server-side configuration. Do not embed a workspace API key in public browser code. Use an OAuth access token when an operation must act as a signed-in user; client-side MCP routes specifically require the user’s OAuth identity. The SDK follows a Result-based response pattern. Check isErr() before reading value, and handle API errors before continuing. The Conversations API reference lists request fields and available operations.
