composio-community/awesome-claude-plugins

A curated list of Plugins that let you extend Claude Code with custom commands, agents, hooks, and MCP servers through the plugin system.

What it is

This repo is a hand-picked list of plugins that extend what Claude Code can do — from sending emails and creating GitHub issues to generating front-end designs, writing tests, and managing cloud costs. The plugins live in folders, each following a standard structure so Claude Code can load them.

The flagship plugin: `connect-apps`

The repo's main focus is the connect-apps plugin. It gives Claude the ability to take real actions — not just generate text — across Gmail, Slack, GitHub, Notion, and 1,000+ other services. You can ask Claude to send you a test email, and if it arrives, you've confirmed the connection works.

How it works

Clone the repo and run Claude with a plugin:

git clone https://github.com/composiohq/awesome-claude-plugins.git
cd awesome-claude-plugins
claude --plugin-dir ./connect-apps

Run setup with /connect-apps:setup and paste a free API key (from dashboard.composio.dev).
Try it — e.g., ask Claude to send you a test email.

You can load multiple plugins at once by passing several --plugin-dir flags.

The plugin catalog

The README lists plugins in categories:

Each entry is either a local folder (included in this repo) or an external link.

Plugin structure

Every plugin follows a standard layout:

plugin-name/
├── .claude-plugin/plugin.json   # Metadata
├── skills/                      # Optional skill definitions
├── commands/                     # Optional slash commands
├── agents/                       # Optional agent definitions
└── hooks/                        # Optional event hooks

The MCP Gateway angle

The README highlights Composio's MCP Gateway — a single endpoint that gives Claude secure access to 1,000+ integrations with built-in authentication, team access controls, and audit logs. The connect-apps plugin is the hands-on example of this.

Contributing & license

Anyone can add a plugin: fork the repo, add a folder with the standard structure, update the README, and submit a pull request. Requirements: the plugin must solve a real use case, avoid duplicating existing functionality, follow the template, and be tested. The repo is MIT licensed (individual plugins may have their own licenses).

Bottom line

If you use Claude Code and want it to do things (send emails, open PRs, catch bugs, deploy code) instead of just answering questions, this repo is a one-stop catalog — with the connect-apps plugin as the main entry point for connecting Claude to your real-world tools.
