Plugins

composio-mcp

Connects Claude Code to the Composio Connect MCP server — gives Claude direct access to 1000+ apps with managed auth, intelligent tool routing, and programmatic tool calling. No API keys needed.

Skills:

• /composio-mcp:composio-mcp — how the Connect MCP works: tool discovery, execution, connections, remote workbench
• /composio-mcp:onboarding — interactive setup: pick your apps, connect them, see what you can do
• /composio-mcp:company-activity-summary — cross-app activity summary (Slack, GitHub, Notion, Linear, etc.)

composio-cli

Adds Composio CLI skills to Claude Code. The CLI lets you execute tools, connect accounts, script workflows, and more from the terminal.

Skills:

• /composio-cli:composio-cli — points to the auto-installed CLI skill (run composio --install-skill claude to get it)
• /composio-cli:onboarding — interactive setup: install CLI, sign in, connect apps
• /composio-cli:company-activity-summary — cross-app activity summary using the CLI

Team setup

Add this to .claude/settings.json in any project repo to auto-prompt team members:

{

    "composio": {
      "source": {
        "source": "github",
        "repo": "ComposioHQ/composio-plugin-cc"
      }
    }
  },
  "enabledPlugins": {
    "composio-mcp@composio": true,
    "composio-cli@composio": true
  }
}

Updating

Bump the version in the plugin's .claude-plugin/plugin.json, push to GitHub, and users will get updates automatically (if auto-update is enabled) or via:

/plugin marketplace update composio
/reload-plugins
