Connect Apps

Connect Claude to 1000+ apps. Actually send emails, create issues, post messages - not just generate text about it.

Quick Start

Step 1: Install the Plugin

/plugin install composio-toolrouter

Step 2: Run Setup

/composio-toolrouter:setup

This will:

  • Ask for your free API key (get one at platform.composio.dev)
  • Configure Claude's connection to 1000+ apps
  • Take about 60 seconds

Step 3: Try It!

After setup, restart Claude Code and try:

Send me a test email at YOUR_EMAIL@example.com

If it works, you're connected!

What You Can Do

Ask Claude to...What happens
"Send email to sarah@acme.com about the launch"Actually sends the email
"Create GitHub issue: fix login bug"Creates the issue
"Post to Slack #general: deploy complete"Posts the message
"Add meeting notes to Notion"Adds to Notion

Supported Apps

Email: Gmail, Outlook, SendGrid Chat: Slack, Discord, Teams, Telegram Dev: GitHub, GitLab, Jira, Linear Docs: Notion, Google Docs, Confluence Data: Sheets, Airtable, PostgreSQL And 1000+ more...

How It Works

  1. You ask Claude to do something
  2. Composio Tool Router finds the right tool
  3. First time? You'll authorize via OAuth (one-time)
  4. Action executes and returns result

Troubleshooting

  • "Plugin not found" → Make sure you ran /plugin install composio-toolrouter
  • "Need to authorize" → Click the OAuth link Claude provides, then say "done"
  • Action failed → Check you have permissions in the target app
