Connect Apps

/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
- You ask Claude to do something
- Composio Tool Router finds the right tool
- First time? You'll authorize via OAuth (one-time)
- 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
