Editorial Team
The Authority AI Tools editorial team maintains this directory using vendor documentation, dated source checks, product changelogs, and clearly identified hands-on observations where available.
Cursor’s latest changelog entry (labeled 3.9) is about customizing Cursor — bringing plugins, skills, MCPs, and related configuration together and making team marketplaces more capable. (https://cursor.com/changelog)

One page to manage everything
Cursor 3.9 adds a single customization page to manage plugins, skills, MCPs, subagents, rules, commands, and hooks — and you can do it at the user, team, or workspace level. (https://cursor.com/changelog)
Instead of hunting through separate settings for each capability, this consolidates configuration in one place and makes it clearer what’s applied at which scope.
Bring your own custom MCPs
Cursor now supports custom MCPs, letting you bring your own Model Context Protocol servers into the customization workflow rather than relying only on prebuilt options. (https://cursor.com/changelog)
Marketplace leaderboard and plugin canvases
For teams, Cursor 3.9 adds:
- Marketplace leaderboard: team-wide visibility into the most popular plugins, skills, and MCPs, with one-click installation. (https://cursor.com/changelog)
- Plugin canvases: prebuilt, reusable setup templates for teams — for example, a Hex canvas for data visualizations and an Atlassian canvas for real-time views of issues, projects, and documents. (https://cursor.com/changelog)
Expanded team marketplace imports
Team marketplaces now support imports of plugin repositories from GitLab, BitBucket, or Azure DevOps, broadening where teams can source and share their customizations. (https://cursor.com/changelog)
