Cursor’s March 2026 Updates: JetBrains Integration and Smarter Agents

I reckon we’ve all felt that tug when switching between tools gets in the way of the code. Cursor’s updates from early March 2026 sort that out, bringing agent smarts into JetBrains IDEs and adding interactive bits to chats. Devs, managers, and analysts can now keep their workflows tight without the faff.

✅ Cursor Now in JetBrains IDEs

Cursor plugs into IntelliJ, PyCharm, and WebStorm via the Agent Client Protocol. Pick models from OpenAI, Anthropic, Google, or Cursor for agent-driven coding right in your JetBrains setup. No extra JetBrains AI sub needed; just grab version 2025.3.2 or later, enable the AI Assistant plugin, and install from the ACP Registry.

For Java devs on big enterprise codebases, it indexes your lot securely and runs semantic search to grasp the whole project. Project managers sync Cursor agents with their team’s PyCharm flows for quicker reviews. Analysts generating campaign briefs in WebStorm use it to refactor scripts tied to Shopify inventory pulls without leaving the IDE.

✅ Version 2.6: Interactive UIs and Team Plugins

Agent chats now show interactive UIs, teams share private plugins, and Debug mode got tighter. MCP Apps add charts, diagrams, and whiteboards inside Cursor; admins run team marketplaces for plugin control.

Devs debug React components with live diagrams popping up in chats. Content writers auto-summarise call transcripts from monday.com plugins shared across the team. Marketers trigger automations last Tuesday to check Datadog metrics and tweak ad scripts on the fly.

✅ 30+ New Plugins from Partners

Added plugins from Atlassian, Datadog, GitLab, Glean, Hugging Face, monday.com, and PlanetScale. Cursor reads, writes, and acts across your stack; most pack MCPs for cloud agents in automations.

Researchers pull Hugging Face models to fine-tune on Glean data. Devs link GitLab for PR autofixes after tests. Managers set automations to flag Jira tickets from Slack pings, keeping inventory syncs with PlanetScale humming.

Head to cursor.com and try these in your setup. Chuck feedback on the forum or sub for the next round of changelogs.
