Cursor Plugins
Cursor's official plugin specification and plugin repository.
About
The official repository at github.com/cursor/plugins defines how Cursor plugins are packaged and ships the reference set of plugins. Each plugin is a standalone directory at the repository root with a .cursor-plugin/plugin.json manifest, plus conventional skills/, rules/, and mcp.json directories; a root .cursor-plugin/marketplace.json lists all plugins in the marketplace. The repo includes developer-tools plugins (continual-learning, thermos, orchestrate, pstack, ralph-loop, cli-for-agent, create-plugin, advisor, cursor-sdk) and roughly 90 integration plugins covering Gmail, Google Calendar, GitHub, Playwright, Salesforce, Shopify, Slack-adjacent services, and more. It is MIT licensed and also serves as the reference spec for third-party plugin builders.
What it can do
- Reference plugin manifest spec: `.cursor-plugin/plugin.json` per plugin, `.cursor-plugin/marketplace.json` for the marketplace
- Official plugins: skills/, rules/, and mcp.json components per plugin
- Developer-tools plugins: thermos (security audits with parallel subagents), orchestrate (fan-out to cloud agents), pstack (rigorous agent workflows), ralph-loop (iterative self-referential loops), continual-learning (transcript-driven AGENTS.md memory updates)
- Productivity plugins: Gmail, Google Drive, Google Calendar, Google Docs, Sheets, Slides, Teams, SharePoint
- ~90 integration plugins: GitHub, Playwright, Salesforce, Shopify, HubSpot, Intercom, Zoom, and more
- cursor-sdk for building apps, scripts, and automations with the TypeScript SDK
