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!

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
