Cursor SDK Now Available: Build Agents with TypeScript

TL;DR

• Cursor SDK is now in public beta — build agents programmatically with TypeScript
• Run agents locally or on Cursor's cloud infrastructure with any frontier model
• Cloud Agents API redesigned for better streaming, lifecycle control, and error handling

New

• Cursor SDK (TypeScript) — Access the same runtime and models powering Cursor's desktop, CLI, and web apps. Install with npm install @cursor/sdk and start building agents in minutes.
• Cloud Agents API v1 — Reworked around durable agents and per-prompt runs with first-class SSE streaming, reconnect support via Last-Event-ID, and explicit lifecycle controls (archive, unarchive, delete).
• Run-scoped operations — Follow-ups, status checks, streaming, and cancellation now operate at the run level for clearer state management.
• Standardized responses — v1 API now includes structured error codes, items list responses, and separate agent / run objects.

Getting Started

• Token-based consumption pricing applies. Check the SDK docs and announcement for details.
• Fork sample projects from the public cookbook repo to jumpstart your use case.
• Use the Cursor SDK plugin to get IDE assistance while building.

Update: Run npm install @cursor/sdk to get started.
