MSApps Claude Plugins

If you find these plugins useful, please ⭐ star this repo — it helps other developers discover the marketplace and motivates us to keep building!

The largest open-source plugin marketplace for Claude. 26 production-ready plugins for Claude Code (CLI) and Cowork (desktop app) — built on the SOSA™ security framework.

Upload to Google Drive. Track time in Toggl. Transcribe YouTube videos. Send WhatsApp messages. Manage WordPress. Prospect with Apollo. Clean your Mac. All from a single Claude conversation.

# Add the marketplace (one-time)
/plugin marketplace add MSApps-Mobile/claude-plugins

# Install any plugin
/plugin install google-drive-upload@msapps-plugins

That's it. No API wrappers. No config files (for most plugins). Just install and talk to Claude naturally.

Why This Exists

AI plugins today have a trust problem. Most are demos — not production tools. They hardcode credentials, skip confirmation on destructive actions, and have no concept of agent boundaries.

We built SOSA™ (Supervised Orchestrated Secured Agents) to fix that — a four-pillar methodology for production-grade autonomous AI operations. Every plugin in this marketplace declares its compliance level, impact classification, and security posture.

The four pillars:

Developer Tools

Notion Skills (from Anthropic)

Four official Claude skills from the Anthropic Notion team — announced by Claude on LinkedIn and distributed via notiondevs.notion.site/notion-skills-for-claude. Re-packaged here as installable plugins; skill content is © Anthropic.

Requires the Notion connector (Claude Code MCP or Cowork Settings).

Mobile devs: swift-lsp ships with Xcode — zero extra setup. kotlin-lsp installs via brew install kotlin-language-server.

Pro tip: Run sosa-compliance-checker on all your installed plugins — not just ours. It catches hardcoded API keys, missing confirmation gates, unpinned packages, and prompt injection vulnerabilities in any plugin.

Quick Start

Claude Code (CLI)

# 1. Add marketplace (one-time)
/plugin marketplace add MSApps-Mobile/claude-plugins

# 2. Install what you need
/plugin install mac-disk-cleaner@msapps-plugins
/plugin install youtube-transcriber@msapps-plugins

# 3. Just talk to Claude
# "Clean up my Mac" / "Transcribe this video: https://..."

Cowork (Desktop App)

1. Settings → Plugins → Marketplaces → Add → MSApps-Mobile/claude-plugins
2. Search for any plugin and click Install
3. Start talking — Claude uses the plugin automatically

Setup Guides

One-time Google Apps Script deployment. Save your config to ~/.cowork-gdrive-config.json:

{
  "url": "https://script.google.com/macros/s/YOUR_SCRIPT_ID/exec",
  "apiKey": "your-api-key"
}

Save your Toggl API token to ~/.toggl-config.json:

{
  "apiToken": "your-toggl-api-token",
  "workspaceId": 1234567
}

Get your token at track.toggl.com/profile.

No config needed — just requires the Claude in Chrome extension. Paste any YouTube URL and ask Claude to transcribe it.

Requires the WhatsApp MCP bridge:

brew install go uv ffmpeg
git clone https://github.com/lharries/whatsapp-mcp.git ~/whatsapp-mcp
cd ~/whatsapp-mcp/whatsapp-bridge && go build -o whatsapp-bridge && ./whatsapp-bridge

Scan the QR code with WhatsApp on first run. Set WHATSAPP_MCP_PATH="$HOME/whatsapp-mcp" in your shell profile.

Set environment variables after installing:

Requires WordPress MCP Adapter on WordPress 6.9+.

Set your token: APIFY_API_TOKEN=your_token_here

Get it at Apify Console → Settings → Integrations.

No manual setup — authenticates automatically on first use.

Requires a Notion connector:

• Claude Code: Add a Notion MCP server to .mcp.json
• Cowork: Settings → Connectors → Notion

No config needed. macOS Ventura+. Only touches auto-regenerated caches — never deletes personal files.

Most other plugins (RTL Chat Fixer, VM Disk Cleanup, Cowork Session Fixer, Fix Chrome Connection, GitHub CLI Health Check, GCloud CLI Health Check, SOSA Compliance Checker) require no configuration — just install and use.
