Cursor Plugins (official)
Cursor Plugins (official) official site ↗Last checked against the official docs:
What it does
Cursor's plugin specification and its official plugins. A Cursor plugin packages rules, skills, subagents, commands, MCP servers and hooks into one install. The repo holds Cursor-made plugins (such as Create Plugin, Advisor and Orchestrate) plus Cursor-packaged integrations for tools like GitHub, Playwright, Gmail, Google Drive, HubSpot and Salesforce. Cursor says every plugin in its Marketplace is manually reviewed before it's listed and must be open source. Plugins in the repo are MIT licensed.
Who it's for
Cursor users who want a ready-made bundle of rules, skills and MCP servers for a tool or workflow, and teams who want to package their own setup.
How to set it up
Open Customize in Cursor's sidebar, find the plugin you want (or browse cursor.com/marketplace), select Install and choose a project or user scope.
Manage what's installed from the same Customize page: toggle MCP servers on or off, and switch rules between Always, Agent Decides and Manual.
To build your own, put a folder with a .cursor-plugin/plugin.json manifest (only name is required) in ~/.cursor/plugins/local/<your-plugin>, then restart Cursor or run Developer: Reload Window:
json{ "name": "my-plugin", "description": "Custom development tools", "version": "1.0.0", "author": { "name": "Your Name" } }Cursor also loads plugins that follow the open Agent Plugins standard (a root plugin.json packaging skills and MCP servers). Private team marketplaces need a Teams or Enterprise plan.
Check the official Cursor Plugins (official) docs for the latest steps.

More Rules & Prompts
- Anthropic
Agent Skills (Anthropic)
Anthropic's public repository of Agent Skills: folders with a SKILL.md file (plus optional scripts and resources) that Claude loads when a task needs them. It includes example skills, the document skills behind Claude's file creation, a skill template and a copy of the Agent Skills spec (the open standard lives at agentskills.io). Many skills are Apache-2.0; the document skills are source-available, not open source.
- Agentic AI Foundation (Linux Foundation)
AGENTS.md
A simple open format for giving coding agents project instructions: one AGENTS.md markdown file in your repo with setup commands, test steps and code style. It is now stewarded by the Agentic AI Foundation under the Linux Foundation, and the agents.md site lists many tools that read it, including Codex, Cursor, goose, OpenCode, Aider, Zed, Kilo Code and GitHub Copilot's coding agent. The site and repo are MIT licensed.
- Google (Android)
Android Skills
Google's official Agent Skills for Android development: SKILL.md instructions that ground coding agents in current Android guidance for tasks where Google's evaluations show LLMs underperform. Examples include migrating XML views to Jetpack Compose, upgrading to AGP 9, setting up Navigation 3, making an app edge-to-edge, auditing R8 configuration and fixing ANRs. They follow the open Agent Skills standard, so they work with Claude Code, Codex, Gemini/Antigravity and other agents that support skills. Apache-2.0.
- Anthropic
Claude Code Plugins (official marketplace)
Anthropic's official plugin marketplace for Claude Code. A plugin bundles skills, subagents, hooks and MCP or LSP servers so you install them in one step. It lists plugins Anthropic maintains (such as commit-commands, code-review, feature-dev and the language-server plugins) alongside plugins from partners and other authors. Claude Code adds this marketplace for you the first time you start an interactive terminal session. The repo is Apache-2.0; each plugin has its own license.
- Cursor
Cursor Rules
Cursor's rules feature gives the Agent persistent instructions. Project rules are .mdc files in .cursor/rules, and there are also User Rules, Team Rules and plain AGENTS.md files.
