Cursor 3 ships parallel AI agents. Here is the multi-agent workflow that actually works.
Cursor 3.0 introduces a unified Agents Window sidebar that lists all active agent sessions across repos, with local agents using the Composer 2 model for fast, workspace-aware edits and cloud agents running offline with persistence for long-running tasks and cross-repo workflows. The platform supports handoffs between local and cloud mid-task, and the Marketplace extends agent capabilities with plugins and MCPs, but manual coordination between parallel agents remains required.
