Cursor 3.7 adds cloud agents management in the Agents Window
TL;DR
Cursor 3.7 adds fast cloud environment setup, /in-cloud subagents for isolated VM tasks, and seamless local-to-cloud session handoffs. Cloud subagents run in the background for long-running tasks such as fixing CI or managing PRs.
What changed
Cursor 3.7 introduces fast cloud environment setup for agents plus /in-cloud subagents that operate in isolated VMs with local-to-cloud session handoffs. Developers and Vibe Builders can now direct these subagents to run in the background on tasks such as fixing CI or babysitting PRs. Basic Users access the same controls directly through the Agents Window.
Why it matters
Developers gain reliable isolation for extended workflows when subagents manage CI fixes without tying up local machines. Vibe Builders keep project flow intact as background processes handle PR oversight in dedicated cloud VMs. This setup outperforms standard local agent runs by keeping sessions portable across environments.
What to watch for
Compare the new cloud subagents against local-only agent modes in Cursor when scaling task duration. Verify the updates by opening the Agents Window in version 3.7 and testing an /in-cloud command on a sample PR task.
Who this matters for
- Vibe Builders: Use /in-cloud subagents to handle long-running PR reviews and CI fixes while you stay in flow.
Amy’s take
Cursor is moving beyond the local IDE by turning the editor into a remote execution orchestrator. The introduction of isolated VMs for subagents solves the compute bottleneck for complex tasks like CI debugging. This is a massive shift for builders who want to delegate background work without slowing down their local machine.
By offloading these tasks to the cloud, Cursor is effectively building a managed infrastructure layer for AI agents. Operators should watch how this session handoff handles state: if it stays reliable, the local-only development model is officially dead. This is about compute portability and persistent task execution, making the IDE a command center for distributed work rather than just a text editor.
