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
