Cursor Launches the Cursor SDK

2026-04-30 · cursor

Cursor is turning its agent stack into a developer platform with the new Cursor SDK. The SDK exposes the same runtime, harness, and models that power Cursor across desktop, CLI, and web.

Key Features or Updates

The SDK lets developers create agents with a few lines of TypeScript and run them locally or in Cursor's cloud. Cursor also published sample projects and a plugin to help users build with the SDK.

Impact on Developers

This is a meaningful move because it turns Cursor from a product into a platform for agent workflows. Teams can reuse the same execution model Cursor uses internally instead of stitching together their own orchestration layer.

How to use it

Install @cursor/sdk, set up a Cursor API key, and create an Agent with your local workspace or cloud target. Then stream events from the run and adapt the sample repo patterns to your own automation.
