Cursor agents can now control their own computers

Summary

Cursor describes cloud agents running in isolated virtual machines with full development environments, letting them use and test the software they create rather than stopping at code generation. Available through the web, mobile, desktop, Slack, and GitHub, the agents onboard onto codebases, produce merge-ready pull requests, and attach videos, screenshots, and logs as validation artifacts. Each agent receives an isolated VM for parallel work and can interact directly with browsers, desktop applications, and other tools; users can control its remote desktop and edit without checking out the branch locally. Examples include implementing and verifying Marketplace source links, reproducing a clipboard-exfiltration vulnerability, testing lint-label changes in Cursor, and walking through cursor.com/docs. Cursor reports that more than 30% of its merged PRs are created by autonomous cloud-sandbox agents, while its next goals include coordinating agents, learning from past runs, and eventually managing production changes end to end.

Takeaways

1. 1

   Isolated VMs let multiple cloud agents work in parallel without competing with each other or the developer for local computer resources.

2. 2

   Cloud agents can validate UI and application changes by operating browsers and desktop software, then provide recorded videos, screenshots, and logs as artifacts.

3. 3

   Cursor reports that more than 30% of its merged pull requests are now created by agents operating autonomously in cloud sandboxes.
