Cursor SDK Public Beta: TypeScript API Turns Cursor's Coding Agent Into Programmable Infrastructure with Sandboxed Cloud VMs

Cursor Changelog·high signal

Cursor released a public beta SDK on April 29, 2026 — a TypeScript API letting developers programmatically create, run, and manage Cursor's coding agents from CI/CD pipelines, scripts, or products. Each cloud-configured agent gets a dedicated sandboxed VM with repo clone and dev environment that persists even if the initiating machine goes offline. Rippling, Notion, Faire, and C3 AI are confirmed early adopters wiring agents into automated build-failure triage.
